Growth Steel Round Bars are all 'hot rolled' and produced using both direct rolling from the continuous casting line (for mild steel deformed bar) and by tempering and reheating to rolling temperatures (high tensile grades). The Growth Steel Round Bars Production is on three dedicated rolling lines and are manufactured under strict quality controls to ensure consistancy and conformity to regional and international standards. Growth Steel Round Bars are manufactured to, and conform to the major world standards for round bar. The standards and grades of Growth Steel steel round bars available are:- BS 4449: 1997, Grade 250 Yield Point – 250 N/mm2 Tensile Str'th – Min. 15% > Yield Str'th Elongation – Min. 22% C: 0.24 – 0.28% max S: 0.060 – 0.068% max P: 0.060 – 0.068% max C+Mn/6: 0.42 – 0.45% max JIS G3101: 2004, Grade SS330 Yield Point – 195 - 205 N/mm2 (depending on diameter) Tensile Str'th – 330 - 430 N/mm2 Elongation – Min. 21 - 28% (depending on diameter) C: N/A Mn: N/A S: 0.050% max P: 0.050% max JIS G3101: 2004, Grade SS400 Yield Point – 235 - 245 N/mm2 (depending on diameter) Tensile Str'th – 400 - 510 N/mm2 Elongation – Min. 17 - 22% (depending on diameter) C: N/A Mn: N/A S: 0.050% max P: 0.050% max SNI 07-2052: 2002, Grade BjTP 24 Yield Point – Min. 235 N/mm2 Tensile Str'th – Min. 380 N/mm2 Elongation – 20 - 24% C: 0.22 – 0.28% Si: 0.15 – 0.35% Mn: 0.30 – 0.60% S: 0.030% max P: 0.030% max SNI 07-2052: 2002, Grade BjTP 30 Yield Point – Min. 295 N/mm2 Tensile Str'th – Min. 440 N/mm2 Elongation – 18 - 20% C: 0.27 – 0.33% Si: 0.15 – 0.35% Mn: 0.60 – 0.90% S: 0.030% max P: 0.030% max
