Stainless Steel MIG welding wire have how many types?
ER304,ER307Si,ER308,ER308L,ER308LSi,ER309,ER309L,ER309LSi,ER310,ER316,ER316L,ER316LSi,ER321,ER347,ER410,
ER430,ER2209,317l
How to choose a suitable gasless mig welding stainless steel wire?or what type of filler wire is best for wire feed welding stainless steel?
The first two designators may be“ER”for solid wires that may be used as electrodes or rodsor they may be“EC’for composite cored or stranded wires;or they may be“EQ”for strip electrodes.
The three- or four-digit number,such as 308 in ER308,designates the nominal chemical composition of the filler metal.
ER307.The nominal composition(wt.%)of this classification is 21 Cr.9.5Ni.4 Mn.1 Mo.Filler metals .
ER308The nominal composition(wt.%)of this classification is 21 Cr10 Ni.Commercial specifications is most often used to weld base metals of similar composition, in particular, Type 304.
ER308Si.This classification is the same asER308except for the higher silicon content.
ER308H.This classification is the same as ER308.except that the allowable carbon content is used for welding 304H base metal.
ER308L.This classification is the same as ER308,except for the carbon content.Low carbon,is less than that of the niobium-stabilized alloys or Type 308H at elevated temperatures.
ER308LMo.This classification is used for welding ASTM CF3M stainless steel castings and matches the base metal with ER316L is desired.
ER309.The nominal composition(wt.%)of this classification is 24 Cr13 Ni.Filler metals.
304 and similar base metals where severe corrosion conditions exist requiring higher alloy weld metal.
ER309Si.This classification is the same as ER309,except for higher silicon content.
ER309L.This classification is the same as ER39,except for the carbon content.
ER309LS.This classification is the same as ER309Lexcent for higher sillicon content.
ER309Mo.This classification is the same as ER309except for the addition of 2.0 percent to 3.0 percent.
ER310.The nominal composition(wt.%)of this classification is 26.5 Cr,21 Ni.Filler metal of this classification is most often used to weld base metals of similar composition
ER312.The nominal composition(wt.%) of this classification is 30 Cr, 9 Ni.Filler metal of this classification was originally designed to weld cast alloys of similar composition.
ER316 weld metal may occur when the following three factors co-exist:
The presence of a continuous or semicontinuous network of ferrite in the weld metal microstructurel
ER316Si.This classification is the same as ER316,except for the higher silicon content.
ER316H.This filler metal is the same as ER316,except that the allowable carbon .
ER316L.This classification is the same as ER316.except for the carbon content.
ER316LSi.This classification is the same as ER316L except for the higher silicon content.
ER317.The nominal composition(wt.%) of this classification is 19.5 Cr14 Ni3.5 Mo, higher than ER316.
ER317LThis classification is the same as ER317except for the carbon content.
ER318This composition is identical to ER316,except for the addition of niobium.
ER321Thenominal composition(wt.%)of this classification is 19.5 Cr.9.5 Niwith titanium added.The titanium acts in the same way as niobium in Type 347.
ER347.The nominalcomposition(wt.%) of this classification is 20 Cr,10 Ni,with Nb added as a stabilizer.
ER347Si.This classification is the same as ER347,except for the higher silicon content.
ER409.This 12 Cr alloy(wt.%) differs from Tvpe 410 material because it has a ferritic microstructure.
ER410.This 12 Cralloy(wt.%) is an air-hardening steel.
ER410NiMo.The nominal composition(wt.%)of this classification is 12 Cr4.5 Ni.0.55 Mo.
ER430.This is a 16 Cr(wt.%) alloy.The composition is balanced by providing sufficient chromium to give adequate corrosion resistance for the usual applications.
ER439.This is an 18 Cr(wt.%) alloy that is stabilized with titanium.
