Why Choose ASME SA240/ASTM A240 UNS S44626 Stainless Steel Sheet?

 

ASME SA240/ASTM A240 UNS S44626, a super-ferritic stainless steel, features 25.0-27.0% chromium, 0.75-1.50% molybdenum, and titanium stabilization (0.20-0.50%), offering exceptional corrosion resistance, good weldability, and moderate strength. Designed for applications requiring durability in highly corrosive and high-temperature environments, such as chemical processing equipment and heat exchangers, it benefits from titanium stabilization and low carbon content (≤ 0.02%) to prevent carbide precipitation during welding, outperforming non-stabilized grades like sa240/a240 uns s43000. Its ferritic structure ensures excellent scaling resistance up to 1050°C (1922°F).

Gangsteel notes that UNS S44626 provides superior corrosion resistance compared to sa240/a240 uns s41008 due to higher chromium and molybdenum content, and it is more cost-effective than super-ferritic grades like sa240/a240 uns s44700. While less ductile than lower-alloy grades, its corrosion resistance makes it ideal for harsh environments.

Key benefits include:

• Exceptional Corrosion Resistance: High chromium (25.0-27.0%) and molybdenum (0.75-1.50%) ensure superior performance in corrosive environments, surpassing sa240/a240 uns s42900.
• Good Weldability: Titanium stabilization enhances weldability compared to sa240/a240 uns s44400.
• High Heat Resistance: Suitable for temperatures up to 1050°C (1922°F), outperforming sa240/a240 uns s43035.
• Cost-Effectiveness: More affordable than sa240/a240 uns s44660.

Case Study: An Indian chemical plant used UNS S44626 sheets for heat exchanger components, achieving a 25% cost reduction compared to sa240/a240 uns s44700 while maintaining excellent corrosion resistance.
