Description
11kp steel is used: for the manufacture of parts with high ductility, the stress and the relatively weak action of aggressive media (precipitation, wet steam, aqueous solutions of salts, organic acids at room temperature); hot-rolled bars intended for the manufacture of clad strips by hot rolling; cold-rolled strip thickness of 1.37 mm and a width of 122−160 mm, intended for manufacturing parts by the method of deep drawing.
Note
Martensite steel-ferritic class. The degree of deoxidation — KP.
