Corrosion Stainless Steel

HEAT RESISTANT STAINLESS STEEL

SH 310 grade is a fully austenitic stainless steel containing 25% Cr, 0.6% Si and
20% Ni additions. The alloy is well known for its multi-purpose high temperature
corrosion resistance behaviour.

Carbon additions are optimized in order to provide improved creep resistance
properties. Alloy SH 310 can be easily welded.

The alloy is designed for high temperature applications up to 1100°C (2012°F) in
oxidizing atmospheres. The alloy can be also used in slightly oxidizing
atmospheres,, nitriding, cementing, sulphurising conditions as well as with thermal
cyclings, but the maximum temperature of use will be reduced.
