AISI 420B Stainless Steel Strip Coil

AISI 420B - a martensitic stainless steel that is corrosion resistant in water and steam.

Martensitic special points:

• High mechanical properities at room temperature, higher than those of austenitics, ferritics and duplex, similar to engineering steels.
• High hardness and wear resistance of the high carbon grades
• Good creep resistance of the Co/V/Nb/W/B grades
• Moderate to good corrosion resistance ( austenitics being good to excellent )
• Magnetic ( both in the annealed and QT state )
• Thermal conductivity up to twice that of austenitic stainless steels
• Thermal expansion coefficient about 2/3 of that of austenitic stainless steels
• Improved machinability grades are available, besides free machining grades e.g. 416, 420F, 440F

Typical applications

• Cutting utensils
• Surgical instruments
• Measuring tools
• Flanges and valves
• Wear-resistant mechanical parts
