The weld deposit has a hardness comparable to that of the original rail. TRI S 370L-O is an over-alloyed austenitic stainless steel that produces a corrosion-resistant deposit in a single layer. It is designed to provide good electrical contact with the rail. HARDFACE 350-S provides resistance to metal-to-metal contact and fretting, making it suitable for the repair of railway wheels. ROBODUR K 600 is a martensitic steel offering good resistance to impact and abrasion, making it well suited to the repair of tamping tines. For more severe abrasive conditions, HARDFACE TIC-O provides a solution with greater wear resistance. 8 7 Wheel Tamping tine Flat-Bottom Rail 5 6 Back to contents page
