Stainless martensitic, precipitation hardening steel, stainless ferritic - Our answer to your needs

Martensitic stainless steels
are characterized by high strength and hardness in the heat-treated condition.
Martensitic grades are magnetic in both the annealed and hardened (heat treated) condition. 
The downstream manufacturer performs final heat treatment to meet the mechanical properties required.
Applications for the martensitic stainless steels include cutlery, knives, scissors, industrial blades, food processing blades, specialty blades, 
surgical and dental instruments, measuring tools, molds, electronics, automotive, mechanical engineering parts, valves, pump parts and components for energy and power generation.

Precipitation hardening stainless steel grades have higher alloying contents than martensitic grades. 
They contain nickel, and in order to achieve hardening by aging additions of copper, aluminum, titanium, niobium and molybdenum. 
Depending on chemical composition their microstructure after final heat treatment is austenitic,semi-austenitic or martensitic. 
Typical applications e.g. oil field equipment, chemical processing equipment, pump shafts, gears, flanges, valves, springs, aircraft parts.

Ferritic stainless steels are nickel free
, usually with 10% to 30% chromium content, and are often chosen for their excellent corrosion 
resistance and elevated temperature oxidation resistance. They are nonhardenable by heat treating and are always magnetic. 
Typical applications for ferritic stainless steels include petrochemical, automotive exhaust systems and trim, heat exchangers, furnaces, architectural building, appliances.
