FCS 421

Standards

EN 14700 ~T Fe7
TS EN 14700 ~T Fe7
DIN 8555 UP 6-GF-50 (55)-C

Properties and Applications

Flux cored wire for submerged arc hardfacing of parts subjected to metal-to-metal wear (adhesion), moderate impact, thermal fatigue and corrosion at high temperatures. Especially designed for hardfacing and renovation of rolling rolls. SHF 604 flux is used together with this wire for hardfacing applications. Has higher level of hardness with respect to FCS 420. Provides smooth and easily machinable surface on stringer weld bead or weaving technique.

Typical Applications : Suitable for hardfacing of rolling rolls which are subjected to high operating temparatures and corrosion and rolls working on similar conditions in iron and steel works. Steel mill rollers, continuous casting rollers.
