Easy slag removal. Applications: build-up of rail heads, rail ends, switch points and pearlitic steel crossings. 0.1 6.0 0.5 19.0 9.0 - Crack-resistant type 307 austenitic stainless steel weld deposit that work hardens depending on the level of impact. Good impact and corrosion resistance. Applications: gauge corners, rail heads, grooves and crossings. 0.06 6.0 1.0 23.5 - - Crack-resistant stainless steel weld deposit specifically designed to restore the rail’s magnetic properties where non-magnetic 307type consumables have previously been used in unsuitable locations. Restores up to 70% of the original rail magnetic response. Applications: gauge corners, rail heads, grooves, crossings. 0.1 6.5 1.0 19.0 9.0 - Special type 307 austenitic stainless steel wire developed for joining grooved rails. The weld shows excellent soundness, meets side-bend test requirements and provides good tensile properties: Rm = 710 MPa and A₅ = 40%. The slag is designed to reduce the risk of entrapment and is easy to remove. Application: grooved rail butt welding. 0.02 6.5 0.7 27.0 9.5 - Over-alloyed wire designed to compensate for dilution with a carbon steel substrate and produce an austenitic stainless steel deposit in a single layer. Good corrosion resistance helps maintain electrical conductivity. Easy slag removal. Application: rail heads. 0.4 16.0 0.6 14.0 1.4 - Non-magnetic austenitic deposit with high resistance to impact and pressure. High work hardening rate. Designed for components exposed to high impact or heavy loads. Applications: repair work on railway frogs and crossings. 1.0 14.0 1.0 0.5 - - Manganese austenitic steel deposit similar to Hadfield steel. Resistant to heavy loads and high impact. Designed for rebuilding 14% manganese steel castings, with a colour similar to the base material. Applications: repair of cast crossings made of manganese steel.
