520 s520 steel tension bar

520 S520 steel tension bar      S520 steel tension bar is produced by carbon or alloy steel round bar with threads by rolling rather than turning, which save the cost. S520 steel tension bar is a kind of high tensile steel rod with yield strength of above 520MPa. It is a kind of structural tension rods used For Construction. Steel materials which can be used to produce s520 tension bar include carbon steel materials s520n and alloy steel materials include: GB AISI/SAE/ASTM JIS DIN 40Cr 5140 SCr440 41Cr4 30CrMo 4130 SCM430 34CrMo4 35CrMo 4135 SCM435 34CrMo4 42CrMo 4140 SCM440 42CrMo4  S520 steel tension bar mechanical properties: Yield strength Tensile strength Elongation Impact (-20.C) 520MPa min 700MPa min 16% min 34J min We can also produce We can also produce polished steel bar, turned steel bar and peeled steel bar and centreless ground bar.
