204 or 304 Stainless Steel: which type is better? The honest answer is that 304 is not automatically better than 204.
They are two different types of stainless steel with different compositions. Both can be strong, durable, rust-resistant, and suitable for food contact. Which type is most suitable primarily depends on the product and the conditions in which it is used.
For a stainless steel lunchbox, snack box, plate, or bowl, quality 204 stainless steel is an excellent choice. At Talli, we use both 204 and 304 stainless steel. Our products are independently tested for food safety by SGS and are made for years of daily use.
Our 204 stainless steel products should not rust under normal use. If they do, you will receive a new product free of charge or a full refund.
204 and 304 Stainless Steel in brief
The main differences and similarities:
- 204 and 304 are both types of stainless steel.
- The number is not a quality score.
- 304 stainless steel generally contains more nickel.
- 204 stainless steel generally contains more manganese and less nickel.
- Both types can be suitable for food contact.
- Both types are rust-resistant.
- The end product, its finish, and the food safety tests carried out are at least as important as the material number.
- Talli's 204 and 304 stainless steel products are independently tested by SGS.
For daily use as a lunchbox or tableware, you therefore don't automatically need to choose 304 stainless steel.
What is 204 Stainless Steel?
204 stainless steel is a type of stainless steel in which part of the nickel has been replaced by other alloying elements, including manganese.
This gives the material different properties than 304 stainless steel but does not automatically make it inferior. Quality 204 stainless steel is strong, durable, and resistant to rust and corrosion.
It is used for kitchen products, food processing products, and other applications where the material must be sturdy, hygienic, and rust-resistant.
What is 304 Stainless Steel?
304 stainless steel is one of the most well-known types of stainless steel. It generally contains more nickel than 204 stainless steel and is used worldwide for a variety of products.
Examples include kitchen products, machinery, pipes, and industrial installations.
Because 304 is so well-known, it is often presented online as the only good choice for food contact. This is too simplistic. Other types of stainless steel can also be perfectly suitable for food and beverages, as long as the composition, production, and finish are in order and the end product has been properly tested.
Is 204 Stainless Steel inferior to 304 Stainless Steel?
No. 204 stainless steel is not automatically inferior to 304 stainless steel.
304 stainless steel is often chosen for applications where a material is exposed to demanding chemical, saline, or industrial conditions for extended periods. A lunchbox or plate is used in a completely different way.
For normal use at home, at school, at work, or on the go, quality 204 stainless steel is a suitable and durable choice.
We do not claim that every arbitrary quality of 204 stainless steel is the same as every quality of 304 stainless steel. There are significant differences between suppliers, compositions, production methods, and finishes.
That is why at Talli, we do not only look at the material number. We examine the actual end product and have it independently tested by SGS.
Is 204 Stainless Steel food-safe?
Yes, the 204 stainless steel that Talli uses for its products is suitable for contact with food and beverages.
The term "food-grade stainless steel" alone is not enough for us. A material may seem suitable on paper, but ultimately, you want to know what happens when the finished product actually comes into contact with food.
That is why we had our stainless steel products tested by SGS, a globally recognized and independent testing institute.
During a migration test, it is investigated whether metals from the stainless steel can be released when the product comes into contact with food. For this purpose, conditions that may be more severe than normal daily use are simulated.
Our tested products have been positively evaluated and found suitable for contact with food according to the applicable European guidelines.
Read more about the test method and view our results in the article about the food safety and SGS test of our stainless steel products.
Is Manganese in 204 Stainless Steel safe?
Manganese occurs naturally in rocks, soil, water, and various foods. It is also an essential trace element that the human body needs in small quantities.
In 204 stainless steel, manganese is used as part of the solid metal alloy. The mere presence of an element in the material does not automatically mean that it will be released into food during use.
That is why a migration test is so important. This not only examines which elements are in the stainless steel but, more importantly, how much can be released from the finished product during contact with food.
Our products have been tested by SGS for this release and found suitable for food contact.
Does 204 Stainless Steel rust?
Under normal daily use, quality 204 stainless steel should not rust.
Our 204 stainless steel lunchboxes, snack boxes, plates, cups, and bowls can be used for food and beverages and are dishwasher safe.
Stainless steel officially means "rust-resistant steel." No type of stainless steel is completely impervious under every conceivable circumstance. This applies to 204, but also to 304 stainless steel.
Aggressive chlorine-containing cleaning agents, bleach, steel wool, and metal scouring pads can damage the protective surface of stainless steel. These are not normal cleaning agents for a lunchbox or plate, and we therefore advise against them.
For normal household use, you do not need to worry about rust with our 204 stainless steel products.
Full warranty against rust
We stand behind the quality of our stainless steel and do not want you to have to take our word for it.
That is why we offer a full warranty against rust formation for our 204 and 304 stainless steel products under normal use.
If rust still occurs, please send us a message via the contact page.
After assessment, you will receive:
- A new product free of charge
- Or a full refund of the purchase price
Is 204 Stainless Steel stronger than 304 Stainless Steel?
204 stainless steel can have higher strength than 304 stainless steel in certain versions and material conditions. However, this does not automatically apply to every product.
The ultimate sturdiness of a lunchbox or plate depends not only on the type of stainless steel. The thickness, shape, construction, and way the material is processed also play an important role.
Therefore, we do not simply say that 204 is always stronger than 304. However, we can say that the 204 stainless steel in our products is strong and suitable for intensive daily use.
Why does Talli use both 204 and 304 Stainless Steel?
Not every product has exactly the same shape, thickness, or function. That is why we choose a suitable stainless steel composition for each product.
For us, every product must meet the same important requirements:
- Safe for contact with food and beverages
- Rust-resistant under normal use
- Sturdy enough for daily use
- Dishwasher safe
- Odorless and tasteless
- Made to last for years
Both our 204 and our 304 stainless steel products meet these practical requirements.
The type of stainless steel used for a specific product can be found in the specifications on the product page. More general information can also be found in our frequently asked questions about stainless steel.
What to look for when buying a stainless steel product?
Only the designation 204, 304, or "food-grade" does not tell the whole story.
When comparing stainless steel products, also pay attention to the following points:
- Is the finished product independently tested?
- Are the test results public?
- Is the product dishwasher safe?
- Is a warranty given for material problems?
At Talli, we make our test results public and offer a warranty if a 204 or 304 stainless steel product rusts under normal use.
Frequently Asked Questions about 204 and 304 Stainless Steel
What is the main difference between 204 and 304 Stainless Steel?
The main difference is the composition. 304 stainless steel generally contains more nickel. 204 stainless steel generally contains more manganese and less nickel. The type number is not a quality score.
Is 204 Stainless Steel safe for a lunchbox?
Yes. Quality 204 stainless steel can be suitable for lunchboxes and tableware. Talli's 204 stainless steel products have been independently tested by SGS and found suitable for contact with food and beverages.
Is manganese a natural material?
Manganese is an element found naturally in rocks, soil, water, and food, among other things. In stainless steel, it is incorporated as part of the metal alloy. For food safety, the results of a migration test are particularly important.
Does 204 Stainless Steel contain less nickel than 304 Stainless Steel?
Yes, 204 stainless steel generally contains less nickel than 304 stainless steel. Part of the nickel is replaced by other alloying elements, including manganese.
Is 304 Stainless Steel safer for food than 204 Stainless Steel?
Not automatically. Food safety depends on the precise composition, production, finish, and release of metals from the end product. Both 204 and 304 stainless steel can be suitable for food contact.
Does 204 Stainless Steel rust faster than 304 Stainless Steel?
Our 204 stainless steel products should not rust under normal use. 304 stainless steel may offer more leeway in certain heavy industrial or chemical conditions, but that does not make 204 unsuitable for a lunchbox or plate.
