TUFALOY 4500X

TUFALOY 4500X

High strength, high ductility anti-wear low temperature electrode with stainless steel core wire, ideal for base layer on manganese steels and railway track components.

PRODUCT DESCRIPTION:

TUFALOY 4500X is a 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 conditions, particularly as a base layer for manganese steels and railway points & crossings.

Product Specification

• Stainless steel core wire ensures balanced weld chemistry
• High ductility and strength with excellent impact resistance
• Crack-resistant, fully austenitic weld matrix
• Free from intergranular carbides
• Ideal base layer electrode for manganese steels and railway track components

• Austenitic stainless steel matrix
• Special alloying elements for toughness and ductility
• Carbide-free micro structure with high crack resistance

• Gouge out and grind fatigued base metal before welding.
• Use short and stringer beads to control heat input.
• Maintain base metal temperature below 200 °C; chill welds immediately after deposition if possible.
• Hot peening of weld bead recommended to convert tensile stresses into compressive stresses.
• Electrode runs on both AC and DC+ power sources.

• Very heavy impact applications
• Crusher and excavator equipment
• Railway points, crossings, and switches
• Mill hammers and blow bars
