AWS A5.36 E71T1-C1A4-Ni1, JIS Z3313 T493T1-1CA-N2
ISO 17632-B-T493T1-1CA-N2
Specification:
E71T1-C1A4-Ni1 is an all-position, flux cored welding wire intended for single and multiple pass welding of low-alloy and carbon steel where a minimum 70 kpsi tensile strength and good notch toughness is required. It is an excellent general purpose welding wire
Purpose:
Most widely used for welding some key structures like shipbuilding, mechanical manufacture, pressure vessels, boilers, petroleum machinery, chemical machinery, hoisting machinery etc.
