Stainless steel tube Vickers hardness test is also an indentation test method for the determination of thin metal material and a surface layer hardness. It has a Brinell, Rockwell method main advantages, seamless stainless steel pipe, and overcome their fundamental shortcomings, but not as good as Rockwell method is simple, Vickers method is rarely used in the steel standards. Stainless steel tube Vickers hardness test is also an indentation test method, decorative stainless steel tube for the determination of thin metal material and a surface layer hardness. It has a Brinell, Rockwell main advantages law, stainless steel, and overcome their fundamental shortcomings, but not as simple Rockwell method, Vickers method is rarely used in the steel standards. 440 - high strength cutting tool steel, stainless steel tube manufacturer, carbon is slightly higher, after appropriate heat treatment to obtain a higher yield strength and hardness up to 58HRC, are among the most hard stainless steel. The most common application example is the "razor blades." There are three common models: 440A, 440B, 440C, in addition 440F (and easy processing). 500 series - heat-resistant chromium alloy steel. 600 Series - martensitic precipitation hardening stainless steel tube.
