Equivalent Materials
Alternative grades comparable to SS490 include ASTM A36, ASTM A283 Grade D, EN S275JO, ISO E275B, DIN 1.0044, and UNS K02401. ASTM A572 Grade 50 represents another viable option with higher strength characteristics. EN S355JR provides superior weldability and machinability as a substitute.
Characteristics
- High tensile strength for superior load-bearing capabilities
- Excellent ductility, allowing formation without compromising structural integrity
- Good weldability, facilitating easy joining and assembly
- Resilience in different weather conditions
- Compliance with strict quality control measures
SS490 demonstrates a better balance of strength, ductility, and weldability compared to other structural steel grades. Its high thermal conductivity allows effective heat dissipation, and its magnetic properties make it suitable for specific applications. The material is valued for its recyclability and energy-efficient production processes.
