1.2714 Hot Work Mould Steel / GB 5CrNiMoV / GOST 5ХНМ2

Leveraging its comprehensive performance advantages, 1.2714 mould steel has become the material of choice in the following critical sectors:

Hot Forging Dies: Forging hammer dies, press forging dies, and forging machine dies, such as those producing critical automotive forgings including crankshafts, connecting rods, and gears.

Die Casting Dies: Core components (e.g., cores, cavities, slides) for non-ferrous metal die casting moulds, including aluminium, magnesium, and copper alloys.

Hot extrusion dies: Die sleeves and die pads for hot extrusion moulds forming aluminium profiles, copper tubes, and similar products.

Plastic moulds (special requirements): A reliable choice for specialised engineering plastic moulds requiring resistance to high injection pressures, high wear, or demanding high surface finish.

Our advantages in Processing 1.2714 Tool Steel

Selecting 1.2714 tool steel is merely the first step. To ensure it realises its full potential, we thoroughly understand and rigorously control both production and quality inspection processes:

Pure Smelting and Uniform Microstructure: Employing advanced smelting techniques (such as Electro-Slag Remelting, ESR), we rigorously control molten steel purity (reducing harmful elements like S and P) and optimise forging processes to achieve a uniform, dense internal structure. This forms the foundation for high toughness and thermal fatigue resistance.

Precision Heat Treatment: Strict adherence to optimised heat treatment curves is paramount. Precise control of austenitising temperatures, holding times, and quenching rates ensures ideal microstructures (e.g., tempered sorbite or bainite). Particular attention is paid to the tempering process, which must be thorough and complete to fully eliminate quenching stresses, stabilise the microstructure, and achieve optimal comprehensive mechanical properties (strength, toughness, and thermal stability). Any deviation in heat treatment may result in significant performance degradation.

Rigorous Non-Destructive Testing: Both mould blanks and finished products undergo stringent non-destructive testing (e.g., ultrasonic testing, UT) to ensure the absence of critical internal defects such as cracks, inclusions, or shrinkage cavities, thereby eliminating safety hazards. For critical components or large moulds, magnetic particle testing (MT) or penetrant testing (PT) are also essential methods for detecting surface defects.
