T5 High Speed Tool Steel Bar

T5 High Speed Tool Steel (T5, 1.3265, S18-1-2-10, SKH4) High speed steel with cobalt The implementation standard is ASTM A600-1992a, ASTM T5 for tungsten series of general cobalt type high speed steel, red hard and high temperature hardness and wear resistance is higher than W18Cr4VCo5 steel, but the toughness is low, after quenching, surface hardness can reach 64 ~ 66HRC. Used for processing materials hardness in more than 400HB complex conditions (heavy load) under the working tool, milling cutter, hob, etc.

Production

T5 High Speed Tool Steel BarW18cr4v is tungsten high speed steel. W18cr4v alloy steel grade means: tungsten high-speed tool steel containing vanadium with an average tungsten content of 18 percent and chromium content of 4 percent. The steel grade of high-speed tool steel is generally not marked with carbon content, only a few percent of the average content of various alloying elements. W18cr4v is widely used in cutting tools, such as turning tool, planer, milling cutter, reamer, tap, drill, etc. The steel is hard at 500℃ and 600℃, and has good cutting performance for a large number of general processed materials.
