Heat-resistant alloy EN 1.4713 / 15Х6СЮ

Steel 1.4713 / 15KH6SJU 


Brand metal 1.4713 refers to low alloy high-temperature alloys of the martensitic type. The basis of steel – iron as alloying elements are manganese, chromium and aluminum. The latter provides great flexibility, minimum weight and ease of processing of workpieces of alloy on the machines of any type.


High-quality heat-resistant steel of grade 1.4713 has high strength, resistance to corrosion of all types (surface, crevice, pitting). The alloy can be used without restriction at temperatures up to 600 degrees Celsius. When this number is exceeded, begins the process of slag formation, which increases the brittleness of steel this brand.

Domestic marking stainless steel of this type 15kh6sju. In the presence of any volume of products in our warehouses. To buy steel you will always help experienced consultants.

The application and use

Stainless steel heat-resistant steel of grade 1.4713 in demand in the manufacture of pipes, fittings, valves. Alloy manufactured parts and elements of boiler equipment, internal combustion engines, turbines. Is produced in the form of billets, the steel sheet that allows you to find broad application, including in construction.
