| 9SiCr |
Is the extensive use of low alloy steel, the higher its quench-hardening ability, quenching rigid, tempering stability is good, better than carbon steel and chromium tool steel. Apply to grading quenching, isothermal quenching, heat treatment deformation when small; Because it contains Si, decarburization larger tendency is extensive use of low alloy steel, the higher its quench-hardening ability, quenching rigid, tempering stability is good, better than carbon steel and chromium tool steel. Apply to grading quenching, isothermal quenching, heat treatment deformation when small; Because it contains Si, larger decarburization tendency |
Often used to make complex shape, distortion and wear resistance of high speed cutting tools, such as drills, taps, BanYa, reamer, gear milling cutter, pull the sword, etc.; Also used for cold mould, such as cold die, print mode, is also used for cold roll, correction roll, etc |
| 8MnSi |
Its quench-hardening ability, its toughness and wear resistance are better than carbon steel. |
Commonly used woodworking tools such as chisel, saw, and small size hot forging die and the punch, hot pressing forging die, bolt, stamping, wire drawing die, l-blot cold die; Also used as a perforation sensor and expansion for the tools and cutting tools. |
| Cr06 |
And Cr2 and 9 Cr2 than its highest carbon content, Cr content minimum, hardened hardness &abrasion resistance are very high, the blade sharp, but brittle |
Most of the cold rolled into BoGang take after use, often used to make razor piece, surgical tools, also can be used as scraper, file, kedao, etc |
| Cr2 |
Hardened hardness &abrasion resistance are very high, quenching deformation is not big, but high temperature plastic poor |
Often used in low speed, small amount of sword, go materials hardness is not high cutting tools, such as turning, milling cutter, inserted knife, reamer, etc.; Also used in the cold mould, drawing die, cold roll, and measuring tools, gauge, sample, eccentric wheel, drilling sheath, etc |
| 9Cr2 |
Performance and Cr2 basic similar, because carbon content is a bit low, its toughness is a good Cr2 |
Mainly used as the cold roll, cold die and the punch, steel cut punching, woodworking tools |
| W |
Hardened hardness and wearability are carbon steel, heat treatment deformation small, water quenching not easy craze, tempering stability is good. |
Often used to working temperature is not high, the cutting speed is cutting tools, such as small manual twist drill, taps, BanYa, reamer, roller of cutting tools, etc |
| 4CrW2Si |
High temperature is good strength and hardness, after the tempering of higher toughness |
Used for high impact load operation of the tools, such as pneumatic tools, cutting composite modulus, such as punching machine shearing tools, as well as part of the small ReZuo mould, such as stress in hot forging die, low heat of the die casting die, etc |
| 5CrW2Si |
Performance and 4 CrW2Si close, after the tempering of higher toughness, has the certain its quench-hardening ability and high mechanical strength, heat treatment on deformation and cracking decarburization, the sensitivity is not big |
Used for manual and pneumatic chisel, caused tools, rivets tools, revive dynamic cutter, cold cutting and trimming with concave die; Also used to ReZuo tools, such as hot punching and perforation tools, hot shear module, hot forging die, the fusion of the gold to die casting die, etc |
| 6CrW2Si |
And four CrW2Si and 5 compared CrW2Si, has high hardness and high temperature quenching certain strength |
Often used to withstand impact load and high wear resistance requirements of tools, such as pneumatic tools, chisel, impact moulds, casting finishing tools, etc.; Also used to ReZuo tools, such as production screws and hot rivet the punch, high temperature alloy die casting light immediate, hot forging die, etc |
