Alloy 330 (NiCr 40/20) is austenitic alloy dope with entity of titanium nitride has a high level of corrosion resistance, particularly to oxidation, carburization and nitridation. It has a solid solution composition and is not hardenable by heat treatment. Its oxidation resistance is enhanced by the silicon content. Can be carry out at temperatures up to 1100°C in neutral atmospheres. It is readily fabricated using standard procedures for stainless steels and nickel alloys.

Applications

Alloy 330 is used extensively in elevated temperatures where resistance to the combined effects of thermal cycling and carburization is required. It is using for industrial heating furnaces; for muffles, retorts, conveyor systems, baskets and boxes, and various fixtures:

• chemical and petrochemical processing
• ore processing
• power generation
1. boiler fixtures
2. gas turbine components
• thermal processing
1. heat-treat furnace containers
2. heat-treat furnace components
3. high temperature fans
4. salt pots
