If you are in the market for stainless steel strips and have no idea which ones to buy, stainless steel strips expert is here to help.
Today we will be looking at the difference between 201 stainless steel strips and 202 stainless steel strips.
Let’s keep reading.
What is 201 Stainless Steel Strip?
Grade 201 stainless steel strip is a lower-cost alternative to the conventional Cr-Ni austenitic stainless steels, such as 304 strips.
About half of the nickel content of 304 is replaced with alloy additions of manganese and nitrogen. This results in a higher strength than 304.
201 stainless steel strip has relatively lower ductility and formability compared to 301 stainless steel strip.
Grade 201 also has good welding characteristics and low temperature properties.
What is 202 Stainless Steel Strip?
202 stainless steel strip is one of the 200 series stainless steel strips, and China standard grade is 1Cr18Mn8Ni5N.
The 202 grade stainless steel strip is the low nickel and high manganese stainless steel material.
The manganese content is around 8%, and it is also a nickel-saving stainless steel.
But 202 stainless steel strip has higher nickel content (4%-6%) compared with 201 stainless steel strip.
Differences Between 201 Stainless Steel Strips and 202 Stainless Steel Strips
Chemical Composition
The chemical components of grade 201 stainless steel strip is summarized in the following table:
| Grade | Standard | C | Si | Mn | P | S | Cr | Ni | Mo |
| 201 | ASTM A240 | ≤0.15 | ≤1.00 | ≤7.50 | ≤0.060 | ≤0.030 | 16.00-18.00 | 3.50-5.50 | – |
The chemical components of grade 202 stainless steel strip is summarized in the following table:
| Grade | Standard | C | Si | Mn | P | S | Cr | Ni | Mo |
| 202 | ASTM A240 | ≤0.15 | ≤1.00 | 7.50-10.0 | ≤0.060 | ≤0.030 | 17.00-19.00 | 4.00-6.00 | – |

Applications
What Is 201 Stainless Steel Strip Used For?
Grade 201 stainless steel strip has good formability and corrosion resistance and this makes it suitable for below applications such as kitchen equipment and catering equipment.
The good strength ensures suitability in applications such as stainless steel banding straps, clamps, brackets and cable ties.
What Is 202 Stainless Steel Strip Used For?
202 stainless steel strip is widely used in building decoration, hotel facilities, shopping malls, glass handrails parts and others.
