APPLICATION
1.2714 steel is mainly used in the manufacturing of die-casting molds (aluminum/magnesium alloys), heavy-duty forging dies (such as automotive crankshafts, connecting rods, and other components that withstand large tonnage impacts), hot extrusion tools, and high-precision plastic injection molds; 1.2714 steel can maintain stable high hardness, excellent thermal fatigue resistance, and impact toughness under high temperature conditions (such as 300-600 ℃) through optimized alloy ratios and heat treatment processes. 1.2714 steel is particularly suitable for harsh environments that can withstand severe thermal cycles and high-pressure loads, significantly extending the service life of molds.
1.2714 Steel Characteristics
1.2714 steel is an alloy hot work die steel with the core advantage of maintaining balanced strength, toughness, and thermal fatigue resistance at high temperatures. It is specifically designed for molds that can withstand severe thermal cycling loads.
1.2714 steel, as a nickel chromium molybdenum vanadium alloy hot work die steel, is designed to withstand severe thermal cycling conditions. Its core advantage lies in maintaining balanced strength, toughness, and thermal fatigue resistance at high temperatures. The chemical composition of 1.2714 steel is optimized through multi-element synergy, with nickel significantly improving toughness, chromium enhancing corrosion resistance, molybdenum and vanadium jointly strengthening high-temperature stability, and impurity elements strictly limited to extremely low levels.
1.2714 steel requires step preheating (400 ℃/800 ℃) followed by oil quenching (830-870 ℃), and then tempering twice at 300-600 ℃ to achieve a final hardness of 52-58 HRC; The slow cooling process can effectively control the risk of deformation.
In terms of mechanical properties of 1.2714 steel, it maintains a hardness of 45 HRC or above and a tensile strength of 800-1000 MPa at a high temperature of 600 ℃. Its impact toughness is superior to similar steel grades, and its moderate thermal expansion coefficient is suitable for precision molds.
1.2714 steel has excellent processing characteristics: soft annealed hardness ≤ 248 HB, good cutting performance; Polishing can achieve a mirror effect and is suitable for surface strengthening treatments such as nitriding (surface hardness exceeding 1000 HV).
1.2714 steel core is used in die-casting molds (aluminum/magnesium alloys), heavy-duty forging dies (such as automotive crankshafts), and hot extrusion tools, especially suitable for impact force scenarios of over 2000 tons.
The nickel content in 1.2714 steel endows it with higher toughness and increases its resistance to softening by 30-50%, thereby extending the lifespan of the mold; Compared with L6 steel, high temperature stability is more prominent.
