British Standard BS4449:2005. Low Carbon Prime Steel Billets are carefully selected for their designated chemistry (Carbon 0.14%-0.22%, Manganese 0.65%-0.9%, Silicon 0.15%-0.25%, Phosphorus 0.05% MAX, Sulphur 0.05% MAX). This material has a high yield strength of 712 MPa and above with an elongation above 14%. Their main application is in the construction of dams, bridges, high-rise buildings, mega structures, etc. cutting tolerance is ±50mm.
