4130

General purpose pipe manufactured to ASTM Specification 519

Available in mechanical tube dimensions of 134.37 mm (5.29") od to 457.2 mm (18") od / 18.11 mm (0.71") wall to 55.25 mm (2.18") wall

Length range up to 10.67 m (35')

4130 has improved weldability compared to 4140 (which has a higher carbon level) though this is achieved at the expense of through thickness strength.

Available in bar dimensions of 50.8 mm (2") to 762 mm (30")

Length range up to 9.14 m (30')
