Hot Worked Mold Steel
Hongxin - 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.
Hongxin - Hot Worked Mold Steel for High-Temperature Tooling and Engineering
JIS SKD6 is a versatile hot work tool steel with 5% chromium, known for its superior impact toughness. Suitable for various industrial applications, including hot work tooling, aluminum and non-ferrous metal processing, plastic molding, and high-pressure die casting, this material excels in high-temperature environments. The steel is categorized under group H in the AISI classification system and conforms to ASTM A681 standards. It is a deep-hardening, air-hardening steel that demonstrates minimal size change during heat treatment. Additionally, JIS SKD6 offers excellent resistance to thermal fatigue cracking and thermal shock, making it robust under both normal and water-cooled operating conditions. With mechanical properties influenced by different heat treatments—such as normalization, quenching, and tempering—the steel's performance can be finely tuned for specific needs. Tests for its mechanical properties include tensile strength, yield strength, impact value, hardness, and grain size. Available in various forms and sizes, the product is delivered based on customer requirements, following rigorous quality assurance protocols.
Hongxin - Hot Work Tool Steel for Plastic Molding
DIN 1.2343, also known as X37CrMoV5-1, is a versatile chromium-based hot work tool steel widely used in tooling and high-temperature industrial applications. It exhibits excellent impact toughness and resistance to thermal fatigue cracking, making it ideal for applications such as hot work tooling, plastic molding, aluminum and non-ferrous metal processing, and high-pressure die casting. This steel can be deep-hardened by heat treatment and air quenching, which minimizes size alteration during heat processing and enhances its stability during repetitive thermal cycles. Featuring a chemical composition that includes chromium, molybdenum, and vanadium, it can withstand stresses and thermal shocks effectively. Its typical mechanical properties, influenced by different heat treatments, include high tensile and yield strength, hardness, and impact values. The typical processes like Electro-Slag Remelting (ESR) enhance its cleanliness and uniformity. Delivery conditions range from hot rolled, annealed to rough turned, depending on the product specifications and customer requirements.Plastic Mould Steel
Hongxin - Plastic Mold Steel
JIS SUS420J2 is a stainless martensitic steel specifically designed for plastic molds and various tooling components. It is favored for its high corrosion resistance, ease of polishing, and superior wear resistance. Commonly used in the manufacture of injection molds and extrusion dies, SUS420J2 exhibits high hardenability and resistance to hot oxidation. The steel grade equivalents include 1.2083, X40Cr14, and 4Cr13. The material’s heat treatment involves annealing at 750-800°C, stress relieving at 600-650°C, preheating at 600-700°C, and austenitizing at 990-1040°C. Quenching involves cooling in oil or a thermal bath. Tempering must be done at 170-270°C to balance hardness and corrosion resistance and repeated at least twice. The material maintains a quenched hardness of HRC 52-56. SUS420J2 can be processed through various stages like normalization, annealing, quenching, and tempering. Its surface conditions can include black, peeled, polished, machined, ground, turned, or milled, and it undergoes extensive testing for properties like tensile strength, yield strength, impact value, and hardness.
Hongxin - Stainless Plastic Mold Steel for Tooling Applications
DIN 1.2083 is a martensitic stainless steel widely used in plastic mold manufacturing and other tooling applications. It offers high corrosion resistance, excellent polishability, and superior wear resistance, making it suitable for precision components like injection molds and extrusion dies. The steel grade can be identified as 1.2083, X40Cr14, SUS420J2, or 4Cr13. It is characterized by good polishability and resistance to both corrosion and hot oxidation. The heat treatment process includes annealing at 750-800°C followed by furnace cooling, stress relieving after machining and before final heat treatment, hardening with preheating to 600-700°C, and austenitizing at 990-1040°C. The steel is then quenched and tempered, typically achieving a hardness of HRC 52-56. The material is available in various forms such as rounds with diameters from 12-500mm and plates/blocks with thicknesses from 8-300mm and widths from 210-710mm. Testing includes tensile strength, yield strength, elongation, hardness, and ultrasonic inspection. Delivery terms are flexible, offering various international trade options.
