SAIL TMT Fe 500S has very high ductility (UTS/YS ratio), high elongation and high uniform elongation, all required for high earthquake-prone areas. The brochure recommends it for high earthquake-prone zones, particularly Zone IV and V.

Key features

• Very high ductility (UTS/YS ratio)
• High elongation
• High uniform elongation

Applications

• High earthquake-prone zones, particularly Zone IV and V
