Search for Equivalents of Valid Grades According to TDP from Various Regions: You can select from American, Russian, Japanese, and European international standards to obtain precise information about equivalent and matching steel grades according to these current standards.
Goto HEGONG SPRING to know more.
Search for Equivalents of Obsolete Grades According to TDP: These are no longer valid but are important for historical comparison or specific technical requirements. These outdated standards (e.g., DIN replaced by EN -1) may still be relevant for the analysis of older projects, the conversion of specifications, or the maintenance of existing equipment.
Search by Character String: If you cannot find the required grade in the previous steps, use the character string search. The application will display steel grades that match the entered character string.
Before selecting a steel grade in the &#;Steel Grade&#; menu, you can narrow the options by selecting a national standard (in the &#;Standard&#; column) and, optionally (though not required), the technical delivery conditions (in the &#;TDP&#; column).
The output list will include matching steel grades according to available national standards, possibly highlighting the steel grade according to the selected national standard (based on selection in the &#;Compare with Standard&#; column).

Want more information on steel grade 50crv4 vs 51crv4? Feel free to contact us.
50HF and DIN / EN equivalent alloys are structural alloys used in the engineering industry for heavy-duty spring components and oil hardened springs.
The steel, unlike other carbon and alloy grades, is characterized by high hardness, low vulnerability to tempering, resistance for variable and heavy loads, and the ability to operate at elevated temperatures up to 300 &#;. Surface-hardened, retains excellent strength properties of the core while maintaining sufficient surface hardness.
58CrV4 / 1. and 59CrV4 / 1. are related grades with the same range of alloying additives. It is distinguished by the higher carbon content, which makes it possible to achieve even higher hardness after heat treatment.
51CrV4 / 50CrV4 / 58CrV4 / 59CrV4 grades are supplied as hot-rolled bars, drawn bars, wires, spring stripes, forgings are used for the production of heavy-duty springs, axles, crankshafts, connecting rods, compression springs, valve springs, springs, shock absorbers or spring washers.
It is mainly supplied in an annealed, softened, heat-treated and raw conditions. Steel does not exhibit corrosion resistance, so products should be protected with greases or coatings.
