Martensitic grade EN 1.4122, DIN X39CrMo17-1 most corrosion-resistant martensitic stainless steel.

Martensitic chromium steel with a carbon content permitting to obtain high tensile strength levels by

heat treatment. Increased chromium content molybdenum addition account for good resistance to

the action of seawater, organic acids and nitric acid, and also for excellent re sistance to crevice corrosion.

The steel presents satisfactory high temperature strength, excellent wear resistance and good antifriction properties.

Typical applications: 

Components for mechanical, marine and plant engineering, pump and compressor parts, sucker rods,

cutting surgical instruments.
