Annealing:440B stainless steel is annealed at 843-871°C (1550-1600°F) and then cooled very slowly in a furnace. Hardening:440B stainless steel is heated at 760°C (1400°F), soaked at 1010°C (1850°F) and finally cooled in oil or air. Tempering:440B stainless steel is tempered at 148°C (300°F) to obtain maximum properties and the 440A Steel :Full Details and Review - Blade ProtectionJul 10, 2020 · 440A steel has decent amounts of Carbon, which can raise its hardness to 55-58 HRC when properly heat-treated. This gives the steel considerable edge retention. However, its not comparable to higher 440 steel grades (440B and 440C), which contain higher amounts of Carbon. Hardness. 440A is a fairly hard steel.

440A/B/C stainless steel sheet and plate - Chanson Metals

440B stainless steel has higher hardness and toughness than 440C steel. 440B stainless steel is used for cutting tools, measuring tools, bearings and valves. Suitable for bayonet blade. 440C is a martensitic stainless steel with higher carbon content than 3Cr13 steel, so its strength and hardness are higher than 3Cr13 steel. 440B Stainless - Special SteelWest Yorkshire Steel are suppliers of 440B stainless steel round bar, diameters. A high carbon high chromium type combining stainless steel properties with excellent hardness after heat treatment. 440B is very similar to the 440C grade but with a slightly lower carbon content, it attains a lower hardness than 440C but has slightly better 440B Steel, Datasheet, Properties, Cross-Reference Table Heat Treatment of steel grade 440B.

Jan 12, 2018 · For 440B, we have 8Cr17, 8Cr17Mo and 8Cr17MoV grades. 440A, we have 7Cr17MoV and 7Cr17. Like Taylor, they use 7Cr17MoV to produce folders. In china, as a saying goes, steel grade is not very important. The good performance is also related to its heat treatment. Everybody who need other info, contact me.
