304 stainless steel flat bar
304 stainless steel definition
304 stainless steel is a common material in stainless steel with a density of 7.93 g/cm3, also known as 18/8 stainless steel.
With high temperature resistance of 800 °C, it has good processing performance and high toughness. It is widely used in industrial and furniture decoration industry and food medical industry.
Among the commonly used marking methods on the market are 06Cr19Ni10, SUS304. 304 generally indicates ASTM standard production, and SUS 304 indicates Japanese standard production.
304 is a versatile stainless steel that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium and more than 8% nickel.
304 stainless steel is a grade of stainless steel produced in accordance with American ASTM standards.
304 stainless steel product standard
For 304 stainless steel, the Ni element in its composition is very important, which directly determines the corrosion resistance of 304 stainless steel and its value.
The most important elements in 304 are Ni, Cr, but are not limited to these two elements.
The specific requirements are stipulated by the product standard.
Common judgments in the industry consider that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel.
This is why the industry calls this type of stainless steel 18/8 stainless steel.
In fact, the relevant product standards have very clear regulations for 304, and these product standards have some differences for different shapes of stainless steel. Below are some common product standards and tests.
To determine if a material is 304 stainless steel, it must meet the requirements of each element in the product standard. As long as there is a non-conformity, it cannot be called 304 stainless steel.
1、ASTM A276
| 304 | C | Mn | P | S | Si | Cr | Ni |
| % | ≤0.08 | ≤2.00 | ≤0.045 | ≤0.030 | ≤1.00 | 18.0–20.0 | 8.0-11.0 |
2、ASTM A240
| 304 | C | Mn | P | S | Si | Cr | Ni | N |
| % | ≤0.07 | ≤2.00 | ≤0.045 | ≤0.030 | ≤0.75 | 17.5–19.5 | 8.0–10.5 | ≤0.10 |
3、JIS G4305
| SUS 304 | C | Mn | P | S | Si | Cr | Ni |
| % | ≤0.08 | ≤2.00 | ≤0.045 | ≤0.030 | ≤1.00 | 18.0–20.0 | 8.0-10.5 |
4、JIS G4303
| SUS 304 | C | Mn | P | S | Si | Cr | Ni |
| % | ≤0.08 | ≤2.00 | ≤0.045 | ≤0.030 | ≤1.00 | 18.0–20.0 | 8.0-10.5 |
The above four standards are just a few common standards.
