SS410 SS420 Stainless Steel Pipes And Tubes 440C Small Diameter Steel Tube

SS410, SS420 stainless steel pipes and tubes, and 440C small diameter steel tubes offer a cost-effective alternative to 300 series stainless steels with specific mechanical advantages for industrial applications.

• Cost Advantage: Significantly lower price than 300 series stainless steels like 304, with less price fluctuation due to nickel market volatility
• Mechanical Properties: Martensitic 400 series stainless steels (410 and 420) achieve high strength and hardness through heat treatment with excellent wear resistance
• Oxidation and Sulfation Resistance: Superior performance in high-temperature oxidizing and sulfur-containing atmospheres compared to 300 series
• Thermal Conductivity: Better heat transfer capabilities than 300 series, ideal for heat exchange applications
• Magnetic Properties: All are magnetic, suitable for electronic or special separation applications
• Resistance to Stress Corrosion Cracking: Superior performance in chloride environments compared to austenitic stainless steels

• Corrosion Resistance: Generally lower than 304 and significantly lower than 316, particularly for acid and pitting resistance
• Formability and Weldability: Inferior to 300 series austenitic steels, with reduced ductility and toughness
• Low-Temperature Toughness: Poor performance in ultra-low temperature environments
