Stainless steel as the name suggests has the added advantage of resistance to corrosion, thus making it favorite among engineers. There are a lot of grades of stainless steel available in the market now intended for different purposes and cost-effectiveness. This abundance in the availability of grades makes it mandatory to have a basic knowledge about each of them to choose the right one for the job. Let us look at the 7 important things to keep in mind while choosing a steel grade. 1. Formability: If you are in the market looking for formable stainless steel, then you should avoid opting for stainless steel such as 410 because they are brittle and not always formable. However austenitic stainless steel could be the right choice. Austenitic grade including ferrite grade could also be ideal for applications involving formability. 2. Weldment: Welding of stainless steel is not always encouraged since it causes serious problems like cracking and corrosio...

Welding wire is a thin metallic rod which upon ignition generates a heated arc which can be used to fuse metal pieces together. In any welded material, welding wire plays the most important role as it determines strength of the finished product. It is possible to combine different alloys and metals however, ultimately strength depends on the welding wire. Different welding wires may be used depending on the metal and job, so the following points should be considered while selecting welding wire. Identify metals : The most common metal used in MIG welding are carbon steel, stainless steel and aluminium. These metals used for welding are called base metals and the influence the required composition and thickness of welding wire. Match wires : The welding wire is ideally the same metal as the metal to be welded. For instance, carbon steel wire should be used for carbon steel material, stainless steel welding wire should be used for welding stainless steel. Th...
