Stainless steel type for every application

Stainless steels have traditionally been divided into categories since the microstructure has a decisive effect on the properties. The categories are made depending on the chemical composition and secondly the manufacturing steps and parameters that determine the microstructure at room temperature.

FERRITIC: The standard ferritic grades are alloyed with chromium (11.2–19%), but with no, or a very small, addition of nickel.

MARTENSITIC AND PH GRADES: For improved strength and hardenability they have a higher carbon content compared to other grades, and nitrogen is sometimes added to further improve strength.

DUPLEX: The duplex grades contribute to high strength and high resistance to stress corrosion cracking. These grades also have a ferritic-austenitic microstructure, with a phase balance of approximately 50/50.

AUSTENITIC: The austenitic grades have good to excellent corrosion resistance, as well as good formability and weldability. This is also the largest group and it is further divided into five sub-groups. These sub-groups are Cr-Mn grades, Cr-Ni grades, Cr-Ni-Mo grades, high performance austenitic grades and high temperature austenitic grades.
