Used to make tools with cutting edges that do not heat up during work, tools with sharp edges and a little toughness that do not withstand impact loads, such as tools for processing wood, hand saws, hand wood tools, machine fines Wood tools, twist drills, drawing dies, punching dies, cold heading dies, screw cones, reamer tools, thread rolling plates, cnc turning tools, planers, milling cutters, currency stamping dies, cold cut edges and punching dies with uniform small cross-sections , Low-precision and simple-shaped pallets, fitter scrapers, hard rock drills, tools for making rivets and nails, screwdrivers, files, chisels for carving, cutters for cutting paper and tobacco leaves, etc.
Tool steel
T11, T11A hypereutectoid steel: it has good comprehensive mechanical properties (such as hardness, wear resistance and toughness, etc.), the grains are finer, and it is less sensitive to the growth of grains and the formation of carbide networks when heated. Used to make tools whose cutting edges do not become hot during work, such as saws, chisel knives, taps, files, scrapers, springs, gauges, reamers, die cutting tools, tobacco cutting tools, small size and no sharp cross-section Varying cold dies and woodworking tools. T12, T12A hypereutectoid steel. Due to the high carbon content. After quenching, there are still many excess carbides, so the hardness and wear resistance are high, but the toughness is low, and the quenching deformation is large. Not suitable for manufacturing tools with high cutting speed and impact load. Used to manufacture tools that are not subject to impact load, the cutting speed is not high, and the cutting edge is not hot, such as turning tools, milling cutters, drill bits, reamers, reamers, taps, dies, scrapers, gauges, blades, small punches Heads, steel files, saws, clockwork, knives for cutting tobacco leaves, and cold-cutting dies and punching dies with small cross-sectional dimensions.
It is used to manufacture metal cutting tools that are not subject to impact loads but require extremely high hardness, such as razors, scrapers, wire drawing tools, files, carving tools, drills, and tools for hard rock processing and carving.
