E9018-B3H4R is preferred for 10 CrMo9 10, it has an advantage for items operating under temperature up to 600 °C , ideal for high creep resistance of boilers and pipe lines of the ancillaries of furnaces and heat exchangers. Crack resistance, tough weld metal, high creep strength, weld metal can be nitrided, quenching and tempering.
