SAF Steelcored 51 description: STEELCORED 51 is a seamless copper coated basic flux cored wire for hardfacing of wearing parts subjected to heavy impact such as pulleys, railway crossings and switch points, rollers, caterpillar track, sprockets, track links
The weld metal is of medium hardness and is machinable by chip-forming. Flame and inductive hardening are possible. Before depositing the final pass, the interpass temperature should not exceed 250C. Due to the very tough and crack-resistant weld metal, a buffer layer is not required.
