Applications:
Alloy 330 is extensively used in high temperature environments where resistance to the combined effects of thermal cycling and carburization is necessary. Applications include:
Chemical and Petrochemical Processing: cracked ammonia components, petrochemical furnace parts, heat exchangers, flares, etc
Thermal Processing: heat-treat furnace containers & compartments, high temperature fans, salt pots, etc
Ore Processing: perlite system and equipment
Power Generation: boiler fixtures, gas turbine components, etc

Corrosion Resistance:
Provides high level of corrosion resistance especially with regards to oxidation, carburization, and nitridation
Has great oxidation resistance and resists scale formation up to about 2000°F due to its chromium and nickel content
Excellent resistance to carburization due to its 34 to 37% nickel and silicon content
Exhibits resistance to nitrogen containing atmospheres where the oxygen content is low
High nickel content also makes it highly resistant to chloride stress corrosion cracking and sigma phase embrittlement
Hardening:
Alloy 330 will not respond to heat treatment; will only harden upon cold work
Machinability
Rigid mounts, sulfurized lubricants, positive feeds and slow speeds are recommended for machining grade 330 stainless steel.
Grade 330 stainless steel can be welded using GAW techniques.
Hot working of grade 330 stainless steel can be performed at 1149 to 1177°C (2100 to 2150°F).
It is difficult to perform cold working in grade 330 stainless steel as the steel has high strength and work hardening rate. However, this steel can be cold worked using strong forces.
Grade 330 stainless steel can be annealed at 1121 to 1204°C (2050 to 2200°F).
