Evek GmbH offers to buy steel strip and strip of steel grades 50KhFA, 50CrV4 or 50hf at economically advantageous prices from the manufacturer. Timeliness of delivery, compliance with the ordered range is guaranteed, as well as delivery to any destination point marked by the customer.

Composition and properties

Rolled sheets of medium-alloy structural steel grade 50KhFA are produced in a wide range of thicknesses and lengths. The chemical composition of this steel of domestic production is defined by GOST 14959. The chemical composition of steel is as follows:

Sulphur (in an amount not exceeding 0.025%) and phosphorus (in an amount not exceeding 0.020%) are present as metallurgical impurities in the composition of this steel.

Poland produces steel 50hf with the same characteristics, and in Germany the analogue of HFA steel 50 according to DIN standard is 50CrV4. The composition of these steels, unlike 50hFA, differs by the expanded tolerances of carbon and manganese content, and vice versa by the reduced silicon content.

The physical and mechanical parameters of this steel grade:

• Ultimate tensile strength, MPa - 940;
• ultimate ductility, MPa - 820;
• Elongation index, % - 20...22 (smaller value corresponds to thin sheet rolling);
• Impact strength at temperatures up to 150...²⁰⁰⁰ С, ^kJ/m2 - 37.
• Brinell hardness, HB - 265...310.

All steel grades under consideration are successfully subjected to various types of heat treatment - annealing, hardening, tempering. Steels of 50XFA type are supplied to consumers in a wide range of thicknesses, lengths and widths of sheets, strips and bands.

Application

Steel 50KhFA (and its listed analogues) is used in the manufacture of critical springs, the working conditions of which require increased durability of products. Steels are resistant to high temperatures (not higher than³⁰⁰⁰ C) and constantly changing sign operating loads. The ability to weld - low, forging must be carried out with low relative strain.

It is economically advantageous to buy rolled sheets - strips, sheets, strips - of spring-grade steels from Evek GmbH. When selling, the prices of the product manufacturer apply, and all purchased batches are accompanied by a certificate of quality.
