Torsid Bars:
TORSID bars are produced from low carbon steel by a special heat treatment process during rolling giving the bar an exceptional combination of strength, toughness, ductility and weldability and has the exact properties of TEMPCORE bars. It complies with all the test requirement of BS 4449 : 1997, MS 146 : 2000, SS2 PART 1 & 2 : 1999 and AS/NZS 4671 : 2001 pertaining to yield stress, tensile strength, elongation, bending, rebending and weldability
