Product Introduction
Application: Used for the welding of atmosphere corrosion resistance materials e.g.locomotive,truck body etc.Such as TSC materials or stainless steel used for the transportation trucks,dissimilar metals e.g.low-carbon steel etc.welding.
Characteristics: This welding wire is 24%Cr-13%Ni type stainless steel welding wire with an excellent corrosion resistance duet to the low carbon content.Its molten iron has a good fluidity due to adding Si so as to realize a more beautiful formation of weld and stable electric arc,available for the all-positioning welding.

Note On Usage:
1.MIG welding shield gas flow should be between 18-25L/min;The shield gas should apply Ar+2%O₂;If the wind speed is greater than 0.5m/s,it is required to take the wind-proof measures.
2.TIG welding shield gas flow requirement:If the welding current is between(15-200)A, the gas flow should be(5-14)L/min;If the welding current is between(200-320)A,the gas flow should be(14-24)L/min.The shield gas should apply pure Ar,and please take the wind-proof measures is the wind speed is greater than 1.0m/s;It is required to remove the impurities e.g. rust,oil contaminant,water etc.on welding workpiece prior to MIG/TIG welding;The above- mentioned welding parameters should be for reference only,users should develop the welding standards appropriate for the production according to their own specific conditions.
Used for high eficiency welding in all positions with excellent welding performance such as warming electric arc,little spatters,beautiful seam forming and easily moved slag.Suitable for welding of 590 MPA high strength steel,steel structure,bridge,steel pipes,railway vehicle,and construction equipment etc.
