Date: 2022-12-15Read: 10
Classification of Stainless Steel
1. According to chemical composition, it can be divided into:Chromium stainless steel, chromium nickel stainless steel, chromium manganese stainless steel, chromium nickel molybdenum stainless steel, as well as ultra-low carbon stainless steel, high molybdenum stainless steel, high-purity stainless steel, etc.
2. According to the metallographic structure, it can be divided into:Martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, austenitic ferritic stainless steel, etc.
3. According to the performance characteristics and applications of steel:Such as nitric acid resistant stainless steel, sulfuric acid resistant stainless steel, pitting resistant stainless steel, stress resistant stainless steel, high-strength stainless steel, etc.
4. According to the functional characteristics of steel:Such as low-temperature stainless steel, non-magnetic stainless steel, easy cutting stainless steel, superplasticity stainless steel, etc.
There are various hardness scores:
1. Rockwell hardness tester - purpose
By using the Rockwell hardness measurement principle, direct Rockwell and surface Rockwell hardness measurements can be performed, and Rockwell hardness values can be converted into HB, HV, HLD, HK, and σ b values.
Suitable for hardness testing of materials such as carbon steel, alloy steel, cast iron, non-ferrous metals, and engineering plastics, it has the characteristics of high testing accuracy, wide measurement range, automatic loading and unloading of main test force, digital display and automatic printing of measurement results, or communication with external computers.
It can be widely used for testing, scientific research, and production in industries such as metrology, mechanical manufacturing, metallurgy, chemical engineering, and building materials.
2. Brinell hardness tester, Leeb hardness tester, Vickers hardness tester, ultrasonic hardness tester, microhardness tester, portable hardness tester, Babbitt hardness tester, Shore hardness tester, etc. Please determine which one is suitable for testing related materials according to specific needs.
