Hardfacing Electrodes
ES 400 / EN 14700: EZ Fe 1
Description
ES 400 is An all position rutile/basic coated electrode that produces a machinable martensitic deposit if weld metal is not quenched, Designed for rolling, sliding and metal to metal wear resistance. Good restriking and low spatter. The electrode can be used with the drag or contact welding technique as well as out of position. It gives a weld metal that is resistant to deformations of high rolling forces including metal -to-metal friction. Weld metal is air hard enable and can be machined with carbide cutting tools. Hardness varies with respect to the number of passes and cooling rate. It has about % 115 metal recovery. Re-drying is 300°C min. 2 h.
