BATOX-HP40Nb
AWS: SFA
EN ISO CODE: 3581-A EZ 25 35 Nb B 6 2
Batox-HP40Nb is a basic coated electrode, specially designed to match heat resistant cast alloys. It is also suitable for the Nb free alloys and leaner high carbon Cr-Ni alloys such as HK40, HT40 and IN519. Weld metal is not prone to sigma phase embrittlement and the presence of eutectic and secondary carbides provide excellent hot strength and creep resistance in the typical service temperature up to 1150 C. Typical applications include pyrolysis coils and reformer tubes for ethylene production in the petrochemical industry.
