Devasco’s YS75-S is recommended for use in joining of AISI 4130, 8630, 8630 modified steels and others with similar mechanical properties. This wire was developed for applications where CVN’s, hardness level, and strength are of utmost importance after a variety of PWHT cycles.
This wire has been specifically designed for welding of quenched and tempered steels that will undergo post weld heat treatment. The chemical composition of this wire combined with the appropriate flux will yield high strength with low temperature fracture toughness while adhering to NACE MR0175 for hardness less than 23 HRc
