The new B3 SC filler metals feature modernized formulations designed for applications that require high toughness also in the post-weld heat treated as well as after-step cooling treatment. The weld metal is also designed for increased rupture resistance at high service temperatures. Filler metal chemistry is carefully controlled so that weldments have a maximum X-bar (Bruscato Factor) of 10, resulting from a very low level of impurity elements to reduce susceptibility to temper embrittlement.
“ESAB offers a complete product solution of B3 alloys for all welding processes to meet industry standards, classifications, chemistries and stringent customers´ mechanical and chemical property requirements,” says Markus Gustafsson, R&D Filler Metal Manager ESAB.
“Further, our hermetically sealed VacPac and BlockPac packaging guarantees additional moisture protection for SMAW electrodes and SAW fluxes, thus eliminating the need for redrying on the customer site.”
