Welcome to Shandong Tengyi Metal Materials Co., Ltd.
ER316LSi
Application: Used for the welding of materials e.g.022Cr19Ni12Mo2(S316L)etc.for petrochemical equipment etc.
Characteristics: This welding wire is ultra-low carbon 19%Cr-12%Ni-2%Mo type stainless steel welding wire with a good corrosion resistance to acetic acid,sulphurous acid, phosphoric acid and salts due to no Mo.Its molten iron has a good fluidity due to adding Si with a beautiful formation,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.
