TUFALOY 4500X
High strength, high ductility anti-wear low heat input electrode with stainless steel core wire, ideal for base layer on manganese steels and railway track components.
PRODUCT DESCRIPTION:
Specially developed anti-wear electrode with stainless steel core wire, designed to deliver optimum chemistry for high toughness and ductility. Its advanced core wire and coating formulation provide a crack-resistant, fully austenitic weld deposit free from intergranular carbides. The electrode is ideal for heavy impact, rolling friction, and abrasion for manganese steels and railway points & crossings.
