Buy a sheet, a wire, a strip of heat-resistant relaxation resistant steel 25KH1MF, as well as foreign counterparts of this material — steel 21CrMoV5−7 and 21hmf, the company offers Electrocentury-steel. Prices — from the manufacturer of the products. The supplier must deliver the goods to any address specified by the customer.
Alloy structural steel 25KH1MF belongs to the group of heat-resistant relaxation resistant. In Russia and the CIS countries, its production is carried out according to technical requirements GOST 20072. In the case of individual production the composition of the steel is governed by THAT of the manufacturer, the name steel — ЭИ10.
The chemical composition of steel 25KH1MF must match what is specified in the table below:
|Content, %||0,22 0,29…||0,4…0,7||0,17…0,37||To 0.3||1,5…1,8||0,25…0,35||0,15 0,30…||0.2|
The composition of the steel as a metallurgical impurities are also available — phosphorus (not more than 0.03%) and sulfur (not more than 0,03%). The closest in composition to foreign analogues of steel 25KH1MF are: in Germany, 21CrMoV5−7 (manufactured according to standards EN and DIN), Poland — steel 21hmf (produced under Polish standard PN). The chemical composition of the analogues are shown in table:
|Content, %||0,17 0,25…||0,4…0,8||To 0.4||To 0.6||1,2…1,5||0,65…0,8||0,25…0,35||0.03|
The percentage of phosphorus and sulfur not more than 0.03%.

Properties and applications
Steel 25KH1MF, 21CrMoV5−7 and 21hmf belong to the group of heat-resistant relaxation resistant steels pearlitic class, and can be used for production of flat parts operated at elevated up to 500…5100 C temperatures Typical components made from these grades of steel are flat spring, parts of the measuring instrument of energy and steam power plants and heat-resistant fasteners. Steel can be tempered, annealing and tempering after which acquire the selling fragility. Sensitive to the formation of placenow, weldability of steels — limited.
Mechanical characteristics of steels after quenching correspond to the following values:
- Tensile strength is 880 MPa;
- The plastic limit is 735 MPa;
- Elongation — 14%;
- The relative narrowing of the cross section — 60%;
- Impact strength is at least 590 kJ/m2 .
