Some uses for |
| W18Cr4V |
Tungsten versatile high-speed steel with high hardness, hot hardness and high temperature hardness, quenching is not easy overheat, easy grinding; drawback is that thermoplastic low toughness somewhat less. The steel had the largest amount, but 20th century reduced |
Turning tools, drills, milling cutters, reamers and other cutting tools for the production of high-speed cutting, also used as a die, taps, reamers, wire drawing dies, saw blades |
| W18Cr4VC05 |
Tungsten cobalt high speed steel , for W18Cr4V high-performance grade, high hot hardness and high temperature hardness, but the toughnesscompared W18Cr4V |
For the production of high-speed machine tools and requirements for heat and to withstand a certain dynamic load tool |
| W18Cr4V2C08 |
Tungsten cobalt high speed steel , the hot hardness, high temperature hardness and wear resistance than W18Cr4VC05 high, but lower toughness |
Suitable for the production of complex conditions in turning, milling, hob tool for against cutting higher strength materials |
| W12Cr4V5C05 |
Tungsten vanadium containing cobalt high speed steel, as quoted in from the United States , once known as the "ace steel with high hardness, especially ultra-high wear resistance, but the grinding performance is poor, poor strength and toughness, not production of complex tool for high-speed cutting |
Suitable for the production require special wear-resistant cutting tools, such as thread chasers, turning, milling cutter, scraper, hob and forming tools, gear cutting tools, etc.; can also be used for cold-working die |
| W6M05Cr4V2 |
W - Mo universal high-speed steel, the world largest amount of high-speed steel steel (M2 ), with higher hardness, hot hardness and high temperature hardness, and thermoplastics, excellent strength and toughness; shortcomings of steel overheating and decarburization sensitivity |
For the production requirements of the wear resistance and toughness with good and withstand the impact of large tools and general tools, such as shaper cutters, bevel gear planer, milling, turning, tap, drill, etc.; for high-load good wear resistance tools, such as cold-working die |
| CW6M05Cr4V2 |
High-carbon the W - Mo general-purpose high-speed steel, due to the carbon content increased, the surface hardness after quenching also increased, and high-temperature hardness, wear resistance and heat resistance are W6M05Cr4V2 high strength and toughness decreased |
Suitable for production of requirement excellent cutting performance of cutting tools |
W6M05Cr4V3
CW6M05Cr4V3 |
High-carbon high-vanadium high-speed steel , the wear resistance thanW6M05Cr4V2 , but the grinding performance is also worse, decarburization sensitivity |
For the production requirements of particularly wear-resistant tools and general tools, such as broaches, hobs, thread chasers, turning, planing tool, tap, drill, etc.Steel grinding poor, creating complex tools, which require special wheel processing |
| W2M09Cr4V2 |
Low tungsten molybdenum steel, which is equivalent to the United States,M7 , with higher hot hardness and toughness, good wear resistance, but decarburization sensitivity |
Mainly used for making thread tools, such as tap, die, etc.; also used for drills, routers, and a variety of cutting tools, a variety of Die |
| W6M05Cr4V2C05 |
W - Mo generally cobalt high speed steel and its thermal rigid and wear resistance thanW6M05Cr4V2 , so good cutting performance, but poor toughness and strength of steel decarburization sensitivity |
Used for the production of high-speed cutting machine tools, cutting tools and high temperature requirements and have a certain vibration loading tool |
| W2M09Cr4VC08 |
W - Mo high carbon containing cobalt super-hard steel, which is equivalent to the U.S. M42 , is a maximum amount of super-hard high speed steel steel, its hardness up to 66 to 70HRC , high hot hardness and high temperature hardness. easy grinding, but poor toughness |
For the production of a variety of complex precision tool, such as precision broaches, forming cutters, special turning tools, drills, and a variety of high hardness tool can be used for difficult to machine materials such as titanium, high temperature alloys, ultra high strength steel machining |
| W9M03Cr4V |
China developed a new type of W - Mo universal high-speed steel, the use of performance and the W1 8Cr4V ( T1 ) and W6MTo 05Cr4V2 ( M2 ), but the process performance is better than T1 and M2 , lower the cost of steel alloy |
To instead W18Cr4V and W6M05Cr4V2 production of a variety of tools |
| W6M05Cr4V2Al |
China's development of the W - Mo (to referred M2Al or 501 ), with high hardness, hot hardness and high temperature hardness, cutting performance and excellent wear resistance and thermoplastic better toughness than containing cobalt high speed steel, but can be somewhat less of the grinding performance of the overheating of the steel and decarburization sensitivity |
For the production of a variety of broaches, shaper cutters, gear hobs, milling, planing, boring knife, turning tools, drill bits and other cutting tools. Long tool life, cutting the general material, its life for W18Cr4V twice, cutting difficult to machine materials, close to the life of cobalt-bearing high-speed steel |
