Blog Brazing & Soldering Manufacturer Lucas-Milhaupt Torch Brazing Stainless Steel Stainless steels encompass a variety of iron-based alloys, having more than 10% chromium, which offer corrosion resistance through a transparent chromium oxide layer. The AWS Handbook lists five categories of stainless steels:Austenitic (nonhardenable) steels (i.e.
The INFERNO and Safety-Silv 56, a brazing filler metal, are used by George in this demonstration. Harris Safety-Silv 56 offers good joint strength and ductility on nickel alloys, which will avoid the possibility of stress corrosion cracking. Safety-Silv 56 is a good color match on stainless steel and it has excellent fluidity that promotes penetration for good strength and elongation. Brazing Fundamentals Lucas MilhauptThe following chart is based on brazing butt joints of stainless steel, using Easy-Flo® filler metal. It shows how the tensile strength of the brazed joint varies with the amount of clearance between the parts being joined. Note that the strongest joint (135,000 psi/930.8 MPa) is achieved when the joint clearance is .0015 (.038mm.) Brazing-stainless perfect for delicate assembliesBrazing-stainless steel is considered easy to perform if a basic understanding of the materials is obtained and if the applicable processes are mastered.. In particular it is advantageous for joining dissimilar materials that cannot be welded together.. When properly applied Brazing-stainless permits to build strong and leak tight joints in thin wall items with minimum deformation.
One thng about stainless is it's trickier to braze because of the oxides which can form. You need to find the correct flux and alloy. I think there is a site called HandyHarmon which gives extensive info on many braze and solder types/uses. Stainless needs to be fluxed and heated just right to braze properly. Can I braze Stainless ? - Weld Talk Message BoardsSoldering means low melting temperatures, usually around 400F or less. Brazing being anything higher than 400F, but not high enough to melt the base metals being joined. One thng about stainless is it's trickier to braze because of the oxides which can form. You need to find the correct flux and alloy. How to Braze with a TIG Welder Welding MastermindThere are several steps you need to undertake to assemble a TIG welding torch to begin a brazing operation. Here is the process of assembling a TIG welding torch:Put the tungsten in the collet. Be sure during this process not to over-tighten or strip the soft, fine copper alloy threads within the welding torch.
For some applications a colour match between the brazing filler metals and the parent metals is clearly desirable. The following SILVER-FLO alloys should be considered.. SILVER-FLO 60, 56 and 55 are silvery in colour and are suitable for use on nickel silver or stainless steel provided that there is no danger of interfacial corrosion ; SILVER-FLO 20, 18 and 16 are more yellow or brass coloured. Metal brazing tips and advice Johnson MattheyFor some applications a colour match between the brazing filler metals and the parent metals is clearly desirable.

Procedures for Brazing Pipe and Tubing The Harris Surfaces may be properly cleaned for brazing by brushing with a stainless steel wire brush or by a stiff rubbing with emery cloth or Scotch Brite®. If oil or grease is present, clean with a commercial solvent. Remember to remove small foreign particles such as emery dust, by wiping with a clean dry cloth. The joint surface MUST be clean.
