UP-101 Mo (S3Mo)

SAW (submerged arc welding) wires for mild and low alloyed steel

Quality UP-101 Mo (S3Mo)
Classification DIN EN ISO 14171-A S3Mo, 24598-A S S MnMo
Material No. 1.5426
Classification AWS A5.23 EA4
Approvals TÜV 03275, CE, DB 52.045.08
Characteristics and application Submerged arc welding wire for 0.5%Mo steels, i.e. P1. These steels are commonly used at service temperatures up to 500°C and for some sub-zero structural applications. The 0.5% alloying improves creep performance compared to CMn steels and sees the alloy being used for boiler, pressure vessel and piping construction. The good general mechanical properties also ensures use in general structural engineering applications.
Base materials For similar alloyed high temperature steels and cast steels, ageing resistant and steels resistant to caustic cracking.
