SAITRON HF 635 is low heat input "Anti-Wear" Cr-Mo alloyed steel electrode. It is used for high build-up as cushioning layers before hardfacing with harder abrasion-resistant weld alloys. Weld deposits is tough and machinable with high compressive strength. Resist severe impact condition when used on Low and Medium carbon steels, Low and Medium alloy steels. High resistance to rolling and sliding friction. Easy welding with self removal slag. Weld deposit is dense and crack free.
