LoTherme OA-430S

A Ferritic Stainless Steel OA wire for Surfacing & Buffer Layer

Characteristics

LoTherme OA-430S deposits ferritic stainless steel weld metal. The weld metal displays good resistance to corrosion and heat. Used commonly as a buffer layer on low alloy steel jobs prior to high alloy hard surfacing applications. The buffer layer takes care of dilution and prevents formation of hard & crack-sensitive martensite microstructure during hard surfacing.

Applications

LoTherme OA-430S is suitable for reclamation of steam & gas turbine components, valve & valve seats and used as buffer layer during re-building of continuous casting rolls.
