SN Steel (Structural Steels for Buildings)

Japan Iron and Steel Federation – Japan

SN steels are recommended to apply to the structural members in which inelastic deformations are anticipated.
Deformation index, which represents the seismic performance of steel materials, is introduced to SN steels along with weldability & toughness indexes.

Characteristics

Optimized Mechanical and Weldability Performance
– Controlled yield characteristics and limited carbon equivalent (Ceq) ensure sufficient plastic deformation and improved weldability for structural applications.
Versatile and High-Performance Steel Options
– Three steel types (A, B, C) offer application-specific flexibility, with C-type providing enhanced mechanical reliability through strict control of impurities and thickness properties.
