Structural steel including:alloy structural steel, carbon structural steel, low carbon alloy structural steel, heat resistant structural steel, etc.
Good quality carbon structural steel compared with normal carbon structural steel, P,S and other unmetal chemical is little.This kind of steel including three series based on Carbon content and application:
