Overview: 440B of martensitic stainless steel. 440B 440A stainless steel hardness higher than 440C high steel toughness. 440B stainless steel for cutting tools, measuring tools and bearings, valves. Suitable for bayonet blade material. Chemical composition: Carbon C: 0.75 ~ 0.95 Mn Mn: ≤1.00 silicon Si: ≤1.00 chromium Cr: 16.0 ~ 18.0 Nickel Ni②: - P P: ≤0.04 sulfur S: ≤0.03 Mo Mo: ≤0.75 Mechanical Properties: Annealing / ℃ : 800 ~ 920 slow cooling quenching / ℃: 1010 ~ 1070 oil cooling tempering / ℃: 100 ~ 180 rapid cooling after annealing hardness HBS≤255; range HBR≥56 Features and application: 440B stainless steel high hardness compared SUS440A, relatively high toughness steel SUS440C. SUS440B for cutting tools, measuring tools and bearings. High hardness and good wear resistance, when polished, its drawback is that relatively large viscosity, and the temperature quickly, but it is more likely than any steel polished, hand sawing material is also much easier.
