SUGGESTIONS FOR WELDING STAINLESS STEEL

Welding of most of the 400 Series stainless steels call for maintaining preheat and interpass temperatures, and in some cases post-weld heating to avoid formation of brittle structure called martensite. Alloy 405, 409Cb, and 430 grades which are ferritic do not require preheat, but it is advisable to heat to 200°F to avoid condensation in the The Importance of Interpass Temperaturepreheat temperature, with regard to the mechanical and microstructural proper-ties of weldments. For instance, the yield and ultimate tensile strengths of the weld metal are both a function of the interpass temperature. High values of interpass temperature tend to reduce the weld metal strength.

Additionally, higher interpass tempera- The wide world of welding stainless steelThis is good because welding ferritic stainless steel is most successful with low heat input, and maximum interpass temperature is 300 degrees F. If you violate that guideline, youll know it soon enough. At high heat inputs, the material begins to experience grain growth and can quickly lose strength.

Stainless Steel. Stainless Steels are a group of high alloy steels that contain at least 10.5% chromium.They are widely-preferred because of their performance in even the most aggressive environments. Stainless steels are usually alloyed with a number of other elements to improve heat resisting properties, enhance mechanical properties and/or fabricating characteristics, and to improve Welding HY Steel and the Precautions You Should TakeApr 02, 2018 · Lower yields, or welds with minimum yield strength, are welded with low hydrogen electrodes whereas higher yield steels are better welded using plasma arc welding with metals of very low impurity levels. Preheating will be needed for thicker plates in an effort to
