321 stainless steel triangle bar

The 321 stainless steel triangle bar (UNS S32100) represents advanced stabilized stainless steel technology, offering exceptional resistance to intergranular corrosion, particularly after exposure to temperatures ranging from 800°F to 1500°F. What sets our 321 stainless steel triangle bar apart is its titanium stabilization, specifically engineered to prevent chromium carbide formation. This unique composition makes it an ideal choice for demanding high-temperature applications.

Advanced Performance Characteristics

Our premium stainless steel triangle bars in grade 321 demonstrate superior mechanical properties at elevated temperatures. The 321 stainless steel triangle bar exhibits enhanced creep and stress rupture properties compared to both 304 and 304L alternatives. Key features include:

• Temperature Resistance: Excellent oxidation resistance up to 1500°F (816°C)
• Corrosion Protection: Superior resistance to intergranular corrosion in the critical 427-816°C range
• Low-Temperature Performance: Outstanding toughness at reduced temperatures

Manufacturing Specifications and Applications

The 321H variant of our stainless steel triangle bar, designated as UNS S32109, features a higher carbon content (0.04-0.10), specifically developed for:

• Enhanced creep resistance
• Improved strength at temperatures above 537°C
• Dual certification capabilities

While these 321 stainless steel triangle bars cannot be hardened through heat treatment, they excel in cold working applications and offer exceptional weldability with standard fabrication practices.
