S7 cold working tool steel characteristics
(1) Excellent corrosion resistance, strong ductility, mold cutting edge damage resistance is good, good toughness
(2) Good hardenability, uniform carbide distribution, a certain impact load and good wear resistance and air quenching performance,
(3) The size deformation after air quenching is small, the carbide is uniform and fine, so the wear resistance is very good.
S7 tool steel supply status
Generally between 52HRC-58HRC, heat treatment can achieve ultra-high strength of HRC55-57
S7 cold used as tool steel
It is used in stamping die, precision stamping die, cold working forming die, cold drawing die, forming roll, punch, drawing die, crimping die, embossing die, wire cutting precision punching die and stamping die for various purposes, plastic deformation tools of difficult materials, cold forging die, deep drawing die and rolling die.
It is used in stamping die, cutting die, cutting die, decoration die, pneumatic tool, hand tool, cutter, knife, decoration tool, cold drill, scissors, stamping die and other hardware die and plastic die. Its easy heat treatment and non-deformation characteristics are very suitable for manufacturing in cold and hot molds, correct.
