德國soudokay SK A45-G氣體保護(hù)藥芯焊絲
SK A45-G high alloyed steels
Classifications gas shielded bl cored wire
DIN 8555
MF 10-GF-65-GT
Characteristics
Chromium-Niobium-Molybdenum alloy with addition of Tungsten and Vanadium designed to
resist high stress grinding abrasion with low impact and solid erosion at service temperatures
up to 650 °C. The deposits will readily show stress relief cracks.
Microstructure: Austenitic matrix with hexagonal primary and eutectic carbides
and nodular Nb carbides with complex combined carbides
Machinability: Grinding only
Oxy-acetylene cutting: Cannot be flame cut
Deposit thickness: 8 to 12 mm in 2 or 3 layers
Shielding gas: Argon + 2 % Oxygen
Field of use
Wear plates, sinter finger crushers, exhaust fan blades in pellet plants, perlite crushers,
bucket teeth and lips on bucketwheel excavators, boiler fan blades, burden area in blast
furnace bells, etc.
