Thick rutile-covered electrode for depositing tough and wear resisting hardfacing overlays. It is particularly resistant to high metal-to-metal wear, moderate impact and abrasion. The weld metal has sufficient red hardness up to +600°C. It is machinable only by grinding. In case of crack sensitive base metals, a tough buffer layer made by ESB 42 or EI 307B electrodes, is required and a further one after every third hardfacing layer. The as-welded hardness of 59 HRc can be increased to 60-65 HRc by single or double tempering. Possible to use equally well both with AC and DC.
Typical Applications: Suitable hardfacing applications where wear resistance at higher temperatures is a prime concern, as in hot cut offs, dies for pressure castings, rolls, crushers excavator parts, bucket edges and bucket teeth, drilling bits, coal planes, conveyor screws.
