Some uses for |
| 6Cr4W3M02VNb |
High strength and toughness of the substrate steel type cold work die steel, high strength, high hardness, good toughness, have a higher fatigue strength |
For the manufacture of impact load and the shape of a cold mold, cold extrusion mold, mold for cold heading, screw punch, Die, cold shear modulus |
| 6W6M05Cr4V |
Low-carbon high speed steel type cold work die steel, good hardenability, and has high hardness, high wear resistance, high strength and good red hardness and toughness |
Used for the manufacture of high impact loads, abrasion resistance of the mold, cold extrusion dies, drawing die, cold heading die, forming die, Die, red top |
| 5CrMnMo |
Nickel-free hot work die steel, performance and 5CrNiMo the hardenability less; This steel has excellent toughness, strength and high wear resistance is not sensitive to temper brittleness |
For small, simple shapes forging mold forging hammerwith the module (side length ≤ 300 to400mm) |
| 5CrNiMo |
With good toughness, strength and high wear resistance, and good hardenability, toughness and thermal fatigue resistance at high temperatures above 5CrMnMo |
The country has been widely used for a variety of large forging die, but in recent years that should not be used in the manufacture of large, complex, and higher operating temperature, heavy loads mold |
| 3Cr2W8V |
Is a ledeburite, high hardness at elevated temperatures, but its toughness and ductility poor hardenability middle section thickness ≤80mmCan hardenability; this steel, a higher transition temperature , good thermal fatigue resistance |
Used as high temperature, high stress but from the impact load of the punch, concave die, such as flat on forging die and punch, set pieces, copper alloy extrusion die, die casting with mould; Also for high temperature hot shear knife, etc |
| 5Cr4Mo3SiMnVAl |
Matrix of cold hot amphibious steel type new work steel mold, its quench-hardening ability and quenching rigid were well, as ReZuo steel mold, has the high temperature strength and has high heat resistance, cold hot fatigue sex; As cold die, with high toughness |
Used for industry and bearing industry standard of the hot extrusion die, and cold heading mold, punching concave die etc, can instead of 3 Cr2W8V, Crl2MoV use |
| 3Cr3M03W2V |
With good cold heat processing performance, high thermal strong sex, thermal fatigue performance, good wear resistance and resistance to tempering stability, and a certain impact resistance resistance, quenching rigid is better |
Used for dui forging die, fine forging die, roll forming die have been introduced with mould etc, press ReZuo mold |
| 5Cr4W5M02V |
The new ReZuo steel mold, high thermal, rigid, high strength and high wear resistance, resistance of tempering stability and certain impact toughness, but general heat treatment or heat treatment and chemical isothermal heat treatment |
Often used in the manufacture of hot extrusion dies, can substitute 3 Cr2W8V, also used to make fine forging die, hot stamping, etc |
| 8Cr3 |
Has good its quench-hardening ability, a certain amount of room temperature and high temperature strength, the formation of small carbon and evenly distributed, wear-resisting performance is good |
Often used to shock vibration of smaller, working temperature is below 500 ° C wear resistance of the mold, such as hot, hot stamping die mould, hot side top forging die, forming dies, hot bending die, etc |
| 4CrMnSiMoV |
It has higher temperature mechanical properties, heat-resistant fatigue performance is good, can replace 5 CrNiMo use |
Used to make hammer forging die, press forging die, correction mode, hot bending die, etc
