S3103 302 stainless steel

S3103 302 stainless steel has good plastic, toughness and strength, as well as a certain hardness, can withstand vibration and shock loading, but poor cutting ability. For the manufacture of shock loading is not, and is required to have appropriate hardness and wear resistance, and good toughness tools, such as forging dies, chisels, hammers, punches, metal shearing blade, reamer, symbol, woodworking tools, pneumatic tools, machine top, fitter tools, drilling tools, blunt surgical appliances. T8, T8A eutectoid steel. When quenching prone to overheating, deformation large, relatively low ductility and strength, not manufactured to withstand greater impact tool, but after heat treatment with high hardness and wear resistance. Tools used to manufacture cutting edge constant heat at work, such as carpentry tools, pneumatic tools, bench tools, simple mold, rivets die, the center hole gun and die, cutting steel tools, bearings, tools, aluminum tin alloy die-cast plate and core, and a variety of spring. T8Mn, T8MnA eutectoid steel. It has high hardenability and hardness, but lower ductility and strength. For the manufacture of a large section of woodworking tools, Hack-saws, engraving tools, rivet dies, the mainspring, band saw blades, circular saw blades, coal chisel, masonry chisel and other. T9, T9A hypereutectoid steel. It has high hardness, but low ductility and strength. For the manufacture of high hardness and toughness of a certain variety of tools, such as engraving tools, rivet dies, press die, punch, woodworking tools, agricultural cutting parts, drilling tools and molds split nails.
