production
The base of a steel circle marks 20H23N18 (ЭИ417) are iron, Nickel and chromium. Thanks to the latest elements, the surface of the material when in contact with atmospheric air is covered by a solid film of oxide nature, which protects the product from harmful influence of aggressive environment. Nickel gives the composition ductility. 20H23N18 alloy contains additives of silicon and manganese, which enhance the useful qualities of the material.
