Instruction of Stainless Steel 330 Coils

Alloy 330 is an austenitic, nickel-chromium-iron-silicon alloy that has outstanding resistance to oxidation and carburization up to 2200°F with high strength. The excellent resistance to oxidation and carburization is provided by the high nickel and chromium content of the alloy, further enhanced by its silicon content. Alloy 330’s ultra high nickel content of 34 to 37% also provides high resistance to chloride stress corrosion cracking and embrittlement from the precipitation of sigma phase in most furnace atmospheres. Alloy 330 also has a low coefficient of expansion, excellent ductility, and high strength.

Features of Stainless Steel 330 Coils

1. Stainless Steel 330 Coil 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

2. Stainless Steel 330 Coil Hardening:

  • Alloy 330 will not respond to heat treatment; will only harden upon cold work

3. Stainless Steel 330 Coil Machinability:

  • Rigid mounts, sulfurized lubricants, positive feeds and slow speeds are recommended for machining grade 330 stainless steel.

4. Stainless Steel 330 Coil Cold Working:

  • 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.

5. Stainless Steel Coil Anealing:

  • Grade 330 stainless steel can be annealed at 1121 to 1204°C (2050 to 2200°F).

Marking and packaging of Stainless Steel 330 Coils

The packaging of our products (eg. weathered corrugated steel, weathering corrugated steel,corten steel columnl,hot rolled stainless steel plate) ensures that they will not be damaged during transport. For export purposes, the usual export packaging is done in wooden crates or crates. All hr sheet metal, plates and coils are marked with a logo (company mark), grade, size and batch number. On request, we can customise the marking on the product,such as spcc cold rolled steel.

The Applications of Stainless Steel 330 Coils

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
