A5.28 ER80S-D2, A5.28 ER90S-D2
MIG/GMAW wire for welding of high strength steels, used predominantly after stress relieving. Predominantly used for welding high strength steels, providing a good combination of strength and toughness. May find use for joining creep resistance steels up to about 500°C but the ED-SG Mo wire would be the more usual choice.
For a wide range of engineering steels with a yield strength up to 540MPa (78ksi) and tensile stregth up to 620MPa (90ksi).
