321 Titanium Stabilized Stainless Steel Plate No.1 Finish 3mm-40mm for Welded Boiler Components

321 Titanium Stabilized Stainless Steel Plate for Welded Boiler Components

Our 321 Stainless Steel Plate is titanium-stabilized to prevent intergranular corrosion after welding, making it the ideal choice for boiler components, heat exchangers, and high-temperature welded assemblies. The No.1 hot rolled finish is suitable for heavy industrial fabrication where post-weld heat treatment is impractical. Available from 3mm to 40mm thickness.

Key Features

• Titanium Stabilized: Ti addition (5xC min) eliminates chromium carbide precipitation in weld zones
• No Post-Weld Annealing Required: Reduces fabrication costs and processing time significantly
• High Temperature Strength: Excellent creep and stress rupture properties up to 900°C
• Good Oxidation Resistance: Suitable for intermittent service up to 870°C

Applications

• Boiler and superheater components
• Heat exchanger tube sheets and baffles
• Expansion joints and bellows
• Furnace parts and radiant tubes
• Petrochemical refinery equipment
• Aircraft exhaust systems and components
