Solderability - Wikipedia
Stainless steel and high alloy steel have a low solderability because the chromium alloying element creates oxides that require aggressive fluxes. The only way that the final category of metals can be soldered is by pre-plating them in a metal that is solderable. ... Read Article
Surface Preparation Of Metals Prior To Plating - NMFRC
Metal with heat or welding scale requires much more processing than non-oxidized cold rolled steel. High carbon steels require a different cleaning process than low carbon types, etc. The cleaning medium must be designed to be compatible with the metal being processed. ... Get Doc
Fully Soldered Metal Roofing: More Complicated Than You Think
Stainless steel sheets are stiffer and more dificult to form and work than copper of similar thickness. Soldering stainless steel also typically requires higher heat due to the material’s lower thermal conductivity. Overheating the metal can result in warp ing and buckling, so the soldering process for stainless steel typically requires a ... Read Document

• Metals and alloys of dissimilar compositions can be hard-soldered (brazed or silver-soldered) together, for example: copper to brass; copper to steel; brass to steel; cast iron to mild steel; and mild steel to stainless steel. ... Content Retrieval
Metal Clay Soldering
Little more porous than other metals. It can be joined by using the same flux, solder and torches as silver and gold but, because of its porosity, PMC will "soak up"solder. We recommend that you use hard solder and, when possible, prepare the areas to be soldered by burnishing to close the pores and reduce the tendency to absorb solder. ... Fetch Content
Brazing Copper Tubing Better And Faster - Sperko Engineering
1) 410 stainless steel furnace brazed using BNi-1 2) Mild steel furnace brazed with copper 3) Copper torch brazed with BAg-1 4) Mild steel torch brazed with BAg-1. The results of all of these tests showed, as did our results, that very little overlap is needed in a brazed joint to get full strength. ... Get Doc
SOLDERING STAINLESS STEEL - Voc.uk.com
About "crevice corrosion" (the correct term for a failed stainless/ silver soldered join). It seems that the silver soldering of stainless steel was stopped complete during the early 50s at Vickers (now BAC) and other aircraft factories because the exact cause of "crevice corrosion" could not be pinpointed. ...

Soldering - Richard Whitehouse
Correct soldering procedures are followed. These procedures can be boiled down to six basic steps. They’re generally simple to perform (some take only a few seconds), but every one of them is essential to the completion of a strong, clean soldered joint. Soldering Technique Silver soldering cannot be accomplished without using flux. ... Access This Document

Suggested when brazing stainless steel and nickel alloys. We DO NOT recommend brazing over joints previously soldered with tin/lead solders. The low melting elements in the solder may prevent proper filler metal/base metal alloying.
