The company says the new B3 SC filler metals feature modernised 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.
