| Cr12 |
Widely used in cold die, with high strength, its quench-hardening ability and wear resistance, quenching deformation is small; But the impact toughness is poorer, brittle crack, easy to form uneven eutectic carbide, thermal conductivity and temperature plastic also is bad |
Often used in the manufacture of bear impact load small and wear resistance of high cold die, punch, cold, cold rolling, the shear knife drilling sheath and drawing die, and gauge, sample, CAM pin, eccentric wheel etc |
| Cr12M01V1 |
International widely applied to the cold die, belong to ledebrite steel. Its quench-hardening ability, quenching with high rigidity and wear resistance; Heat treatment deformation small, high temperature oxidation resistance, quenching and polishing corrosion resistance performance |
Used in the manufacture of all kinds of high precision, long life of cold mould, cutting tools and measuring tools, such as complex shape of punching concave die, cold extrusion die, cold shear knife, rub silk plate, roll silk wheel etc |
| Crl2MoV |
Its quench-hardening ability is high, the section for 300 ~ 400 mm the following workpiece can completely quenching through. The quenching after tempering of hardness and strength, toughness are better than Crl2 high, wear resistance and the plastic is better also, deformation is small, but high temperature plastic poor |
Used in the manufacture of bigger, complicated shape section, undergo large impact load of work of the mould, such as all kinds of punching concave die, trimming mold, steel mold, tensile modulus, roll a die, die drawing seam, thread rub silk plate, cold extrusion mold, cool cutting scissors, circular saw blades, standard tools, measuring tools, etc |
| Cr5M01V |
A2 corresponds to the American steel, has the good empty quenching performance, empty quenching deformation and small size, toughness Mn2V, Crl2 than 9 are good, even small carbide, good abrasion resistance |
Used in the manufacture of toughness, good wearability high cold mould, such as forming dies, filling mold, the punch, cold punch die, etc |
| 9Mn2V |
Economical cold work tool steels, the price is not high and comprehensive mechanical performance than the carbon steel with high hardness and resistance to wear, its quench-hardening ability is good, hardened little deformation, the less sensitive overheating |
Used for production of precision measuring tools, sample, KuaiGui, BanYa; Also used for high wear resistance of the distortion and precision ball screw, grinder spindle, and smaller, cold stamping mould, carving mode, blanking mould and so on |
| CrWMn |
Extensive use of micro deformation steel, its quench-hardening ability is good, little deformation, quenching temperature after tempering high hardness, wear resistance and dimension stability, and good toughness, shortcoming is easy to form the mesh carbide |
Used for manufacturing gauges and complicated shape, high precision of the cold die; Also used to make request distortion and long and complex shape of cutting tools, such as broach, long taps, long reamer, special milling cutters, etc |
| 9CrWMn |
Performance and CrWMn close, but because the carbon content is a bit low, carbide segregation CrWMn better than, and mechanical performance is better, but after heat treatment is a bit low hardness |
Used to make complex shape, high precision of the cold die, and all sorts of measuring gauges etc |
| Cr4W2MoV |
In the new alloy cold modulus steel, eutectic compounds tiny particles, uniform distribution, and have higher its quench-hardening ability and quenching rigid, and better comprehensive mechanical properties and wear resistance and dimensional stability |
Used to make cold die, cold extrusion concave die, blanking mode, rub silk plate, etc |
| 7CrSiMnMoV |
The flame hardening cold die, and has good its quench-hardening ability, quenching temperature range wide, overheating sensitivity small, hardened to gain higher surface hardness, wear resistance and good toughness, heat treatment deformation small |
Used in large set piece of mould, filling mold, the punch, forming mold, tensile modulus, cold die, glue, pottery clay model, block shear blade, paper cutter, roll and machine slideway article set |
