High standard 403 stainless plate steel service is provided by our industry along with maintaining the quality of the 403 stainless plate steel with enhanced features. By providing appropriate heat treatment this alloy can provide a wide range of mechanical properties. 403 stainless plate steel have a lot more to offer such as high mechanical strength, high corrosion resistance, and heat resistance. High degree of resistance can be obtained but this grade cannot withstand severely corrosive environments.

CORROSION RESISTANCE
High degree of resistance to atmospheric corrosion because of its ability to form a tightly adherent oxide film
Maximum corrosion resistance is obtained by hardening and polishing.
Not recommended for use in severely corrosive environments.
OXIDATION RESISTANCE
Resists oxidation up to 1400°F (760°C).
Temperature should not exceed 1200-1300°F (649-704°C) in continuous service.
