Hongxin - Model GB/T 4Cr5MoSiV1 -Hot Worked Mold Steel for Industrial Applications
GB/T 4Cr5MoSiV1 is a versatile chromium-molybdenum-vanadium hot work tool steel known for its excellent balance of properties, making it suitable for various industrial applications. This steel exhibits high resistance to abrasion at both low and high temperatures, combined with excellent toughness, ductility, and machinability. Due to its superior through-hardening properties and minimal distortion during hardening, GB/T 4Cr5MoSiV1 is highly effective in maintaining high-temperature strength and resisting thermal fatigue. It withstands rapid cooling and offers enhanced protection against premature heat checking. The chromium content helps the steel resist softening at elevated temperatures, while the molybdenum and vanadium act as strengthening agents. This material is ideal for hot work tooling, plastic molding, aluminum die casting, metal forming, and extrusion applications. It can be easily welded and formed by traditional methods. Mechanical properties vary with heat treatment processes like normalization, tempering, and quenching to optimize performance for specific uses.GB/T 4Cr5MoSiV1 is a versatile and reliable tool steel that is valued for its excellent combination of properties, making it a preferred choice for a wide range of industrial applications. Hot Work Tooling, Plastic Molding,Aluminum Die Casting,Metal Forming and Extrusion Tooling are all its application.

- GB/T 4Cr5MoSiV1 steel introduction
GB/T 4Cr5MoSiV1Tool Steel is chromium hot work tool steels which are widely used in hot and cold work tooling applications. GB/T 4Cr5MoSiV1 tool steel is characterized by good resistance to abrasion at both low and high temperatures, high level of toughness and ductility, uniform and high level of machinability and polishability, good high-temperature strength and resistance to thermal fatigue, excellent through-hardening properties, very limited distortion during hardening.
GB/T 4Cr5MoSiV1, the molybdenum and vanadium act as strengthening agents. The chromium content assists die steel GB/T 4Cr5MoSiV1 to resist softening when used at high temperatures. GB/T 4Cr5MoSiV1 die steels offers an excellent combination of shock and abrasion resistance, and possesses good red hardness. It is capable of withstanding rapid cooling and resists premature heat checking. Tool Steel GB/T 4Cr5MoSiV1 has good machinability, good weldability, good ductility, and can be formed by conventional means.
- GB/T 4Cr5MoSiV1 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
- Heat Treatment
Annealing
Heat slowly to 1550°-1650°F, hold until entire mass is heated through, and cool slowly in the furnace (40F per hour) to about 1000°F, after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
Stress Relieving
When desirable to relieve the strains of machining, heat slowly to 1050°-1250°F, allow to equalize, and then cool in still air (Strain Relieving). Â
Preheat Prior to Hardening
Warm slightly before charging into the preheat furnace, which should be operating at 1400°-1500°F.
Hardening
GB/T 4Cr5MoSiV1 tool steel is a steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested. The temperature employed is usually 1800°-1850°F, depending on size section.
Quenching
Quench in still air or dry air blast. If complicated forms are to be hardened, an interrupted oil quench can be used. Quench part in oil and remove from bath when it just loses its color (1000°-1100°F). Finish cooling to below 150°-125°F in air, then temper immediately.
Tempering
Tempering practice may vary with size and application, but is usually performed in the range of maximum secondary hardness or higher. Double tempering is recommended. The results below is GB/T 4Cr5MoSiV1 that was air quenched from 1800°F and tempered for 4 hours at various temperatures. The results may be used as a guide, keeping in mind that parts of heavy section or mass may be several points lower in hardness.
- Delivery condition
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
