A Ferritic Stainless Steel OA wire for Surfacing & Buffer Layer
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.
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.
Weld Metal Hardness: 30 - 35 RC
|Current Range (Amps)||200-300||250-350|
