This 403 plate stainless sheet straight chromium stainless steel offers reasonable corrosion resistance and high mechanical characteristics. 403 plate stainless sheet is a corrosion and heat resistant 12% Cr martensitic stainless steel. This 403 plate stainless sheet offers a wide range of mechanical properties that are obtainable by appropriate heat treatments. 403 plate stainless sheet is easily hardened by oil, fan or air cooling and may be tempered at temperatures of up to 1350°F (732°C) to improve fracture toughness. Oil or fan cooling is required in thicker sections.

OXIDATION RESISTANCE
Resists oxidation up to 1400°F (760°C).
Temperature should not exceed 1200-1300°F (649-704°C) in continuous service.
TEMPERING
May be done at a temperature between 400°F -1400°F
Advisable to avoid the 800°F – 1100°F range due to a decrease in impact properties and corrosion resistance.
Strength and hardness decrease in the 800°F – 1100°F while ductility and toughness increase as the tempering temperature is raised.
