DescriptionIndustries and ApplicationsResistance to CorrosionFabrication and Heat TreatmentCommon Trade NamesAlloy 20 is a nickel-iron-chromium based, austenitic alloy with excellent corrosion resistance in chemical environments containing sulfuric acid and many other aggressive media. This alloy is stabilized with niobium to resist intergranular corrosion. Alloy 20 may provide potential cost savings when carefully compared to higher nickel-based alloys, while out performing standard stainless steels.See more on corrosionmaterialsFiller Metals for Welding Dissimilar Steels ILMO Acceptable filler for alloy 20 Stainless Steel Welding (steel) Base alloy, type 201, 202 301, 302 302B, 303 304, 305, 308 304L 309 309S 310 310S 314 316 316L 317 317L 321 347 348 330 403, 405 410, 412 414, 420 430 Acceptable filler for alloy 20 Stainless Steel Welding (plate) Alloy 20 FABRICATION - Rolled Alloys(steel) Alloy 20 FABRICATION Technology Department January, 2001 .

Dec 18, 2014The suggestions for filler on this are thus far fine. Really, stop and think. Corrosion is not an issue for a nickel weldment or the Alloy 20 since you are welding to carbon steel. All you need do is really stay away from SS's that could cause embrittlement. By J.W.

I originally googled alloy 20 and found what I needed as far as what wire to use.
The filler metals for welded stainless steel with stainless steel, or welding stainless steel with duplex stainless steel, welding stainless steel with nickel alloys steel, welding stainless steel with mild steel. When welding stainless steel to mild steel, LDX309L, S32304, S32205, 309L, P5,P10,P16,904L are frequently be used. When welding Stainless Steel to Nickel base alloy steel (plate) People also askWhich is the best filler metal for stainless steel?Which is the best filler metal for stainless steel?Welding stainless steels and nickel alloys is all about cleanliness and choosing the right filler metal. These guidelines are intended as a step-by-step aid to the successful welding of stainless steels and nickel alloys. When both base metals are the same, use the base metal alloy as a guide.Welding Guidelines for Stainless Steel and Nickel Alloys

Acceptable filler for alloy 20 Stainless Steel Welding Selecting Filler Metals for Dissimilar Alloy Welding.(plate) Selecting Filler Metals for Stainless Steel Welding(steel) For welding 304 to itself, use a 308/308L filler metal that offers a matching chemistry. Additionally, 309/309L is recommended for welding 304 to carbon steel or for the barrier layer for overlays on carbon steel. The 316/316L types of stainless steels contain molybdenum (Mo) and are commonly used in more corrosive applications than the 304 type.
Apr 01, 2001Some filler metals weld too hard as compared with the base metal. P-20 is one such material, with an as-welded hardness of 50-55 RC. P-20 should only be used in conjunction with a post-weld heat treatment of 900°F for one hour per inch of thickness. This treatment draws the weld metal back down to the base metal hardness.(plate) Stainless Steel - Grade 316 (UNS S31600)(steel) Chemical FormulaKey PropertiesMechanical PropertiesGrade Specification ComparisonCorrosion ResistanceHeat ResistanceHeat TreatmentWeldingMachiningDual CertificationFe, <0.03% C, 16-18.5% Cr, 10-14% Ni, 2-3% Mo, <2% Mn, <1% Si, <0.045% P, <0.03% S Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels.

If you are welding alloy 20 pipes less than 1/8-inch thick, then use argon gas as your shielding gas. The flow rate should be set at 10 to 20 cubic feet per hour. If you're working with nickel alloy pipes more than 1/8-inch thick, then add helium to your gas because it allows for faster travel speeds.
Step 1 Selection of Filler Metal Alloy for Welding Process. When both base metals are the same, use the base metal alloy as a guide. For example, if joining 316L to 316L, use 316L filler metal. Past experience may show preferential corrosion in the weld, in which case, moving up in alloy content may be required.(plate) WELDING OF STAINLESS STEELS AND OTHER JOINING (steel) properties depends upon alloy content, thickness, filler metal, joint design, weld method, and welder skill. Regardless of the changes that take place, the principal objective in welding stainless steels is to provide a sound joint with qualities equal to or better than those of the base metal, allowing for any
