What is the hardness of stainless steel pipe

The hardness is 281. Different types of stainless steel have different hardnesses. Taking 304 stainless steel as an example, the Brinell hardness is less than or equal to 201, the Rockwell hardness is less than or equal to 92, and the Vickers hardness is less than or equal to 210. Stainless steel hardness Stainless steel hardness HB≤187, HRB≤90, HV≤200. Stainless steel is a high alloy steel that can resist corrosion in air or chemically corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as color plating, but can utilize the inherent surface properties of stainless steel.

Factors related to the Rockwell hardness of stainless steel:

1. After the product is rolled, folded, etc., there will be stress, which will have an impact on the hardness, and solution treatment will also have an impact.

2. The most important thing is the material of the product itself.

3. At the same time, the products of different manufacturers will also be different.

4. The grain size is related to the structure.

5. The control of annealing directly affects the hardness.

Hardness indicates a material's ability to resist hard objects pressing into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance. Commonly used hardness indicators include Brinell hardness, Rockwell hardness and Vickers hardness.
