What is the hardness of high speed steel HRC?
HSS DM06 hardness HRC6266. HSS DM06 tools can be used to cut steel at a speed of 30 meters per second, which is several times more efficient than the carbon and alloy tool steels used in the past. By the speed and quality of high-speed steel can be calculated high-speed steel DM06 hardness HRC6266.
Hardness HRC: 64-6 flexural strength / GPa: about impact toughness / (MJm²): about 3600 ℃ when the hardness of HRC: 5 main purpose: cutting performance is comparable to W18Cr4V, suitable for the production of hot-rolled cutting tools. 5, ① general high-speed steel: mainly used in the manufacture of cutting hardness HB ≤ 300, the commonly used steel number W18Cr4V, W6Mo5Cr4V2, etc., ② Special-purpose high-speed steel: including cobalt high-speed steel and super-hard high-speed steel (hardness, mainly used in the manufacture of cutting metals (such as high-temperature alloys, titanium alloys and highly) W12Cr4V 5CoW2Mo9C, HRC can be above 60.
M2 high-speed steel hardness is usually between 60 ~ 65HRC, belongs to the very hard material, can be used for processing hard materials, such as steel, stainless steel, alloys. M2 HSS has excellent mechanical properties. Its tensile strength is about 1830MPa and yield strength is about 1620MPa. meanwhile, its elongation is high, about 12%.
