HRC Hot Rolled Carbon Steel Coils Cold Rolled Galvanized Steel Plate/GI Slit Coil/Metal Strip price
304 stainless steel does not generally use HRC (there is no standard for 304 stainless steel HRC), only high hardness steel HRC, but 304 is soft.
Stainless steel is generally expressed by vickers hardness, 304 vickers hardness is about 220.

304 stainless steel is a universal stainless steel material with better rust resistance than 200 series stainless steel. High temperature resistance is also better, can be high to 1000-1200 degrees.
304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance.
For oxidizing acid, in the experiment: concentration ≤65% of the boiling temperature of nitric acid, 304 stainless steel has a strong corrosion resistance.
It also has good corrosion resistance to alkali solution and most organic and inorganic acids.
Hardness test is the most simple and feasible test method in mechanical property test. In order to replace some mechanical properties tests with hardness tests, a more accurate conversion relationship between hardness and strength is needed in production.
It has been proved by practice that there are approximately corresponding relations between hardness values and strength values of metal materials. Because the hardness value is determined by the initial plastic deformation resistance and the continued plastic deformation resistance, the higher the strength of the material, the higher the plastic deformation resistance, the higher the hardness value.
