2CR13 stainless steel round bar Hardness

2CR13 stainless steel round bar should be part of stainless steel from the category, a more accurate classification should be attributed to the martensitic stainless iron, 2CR13 stainless steel round bar is mainly for machining of stainless steel has a better than normal price.

Therefore, less demanding corrosion resistance in the case, 2Cr13 stainless steel round bar has been more widely used. 2Cr13 after quenching can be better mechanical properties, and having good processability, martensite morphology type.
