Technical standards and specifications for tool steels according to EN ISO 4957
The international standard EN ISO 4957 sets strict requirements for general-purpose tool steels, defining their classification, chemical composition, and the nomenclature of supplied metal product forms. Products supplied by EV Group China fully comply with these regulatory criteria, ensuring precision when manufacturing complex technological tooling.
Tool steels regulated by this standard demonstrate optimal machinability, high dimensional stability during quenching, and a balanced ratio of surface hardness to impact toughness. EV Group China’s engineering solutions guarantee the durability of tools, which significantly reduces operational costs on production lines.
Application of tool steels
In accordance with the technical annex to EN ISO 4957, these steel grades are recommended for the production of a wide range of metal-cutting and deforming tools. Key areas of application include:
- Manufacturing of tooling for cold blanking, punching, and precision broaching.
- Production of knives for industrial metal cutting and trimming.
- Creation of forming elements for bending and rolling processes.
- Manufacturing of precision measuring instruments, guide bushings, and ejector pins.
- Production of critical mechanical components: cam pairs, pistons, nozzles, and compact gears.
EV Group China specialists provide expert selection of steel grades depending on the required operational loads, ensuring that each batch meets established international quality standards.
