Technical specifications

This steel grade is a nickel-molybdenum stainless alloy with a martensitic precipitation, it exhibits high ductility and toughness. Analogue X5CrNiCuNb16−4… As a rule, this alloy is used when high strength, viscosity, corrosion resistance and resistance to stress-corrosion cracking are required.

The steel is produced in an open arc furnace. This melting reduces contamination and minimizes segregation. Rent passes 100% ultrasonic control:

Heat treatment

It lasts for 4 hours at 620/620 ° C (or 1150/1150 ° F)… This is the most common standard of supply. Technically, during aging, two processes take place: the precipitation of copper and the formation of reversible martensite. The second aging on H1150 + 1150 is used to reduce the hardness values. It has been found that resistance to sulphide stress cracking is given at a maximum hardness of 33 HRC.
