Stainless steel Fabricating is a highly versatile metal and, as a result, it is suited to a wide range of fabrications processes. These processes are generally the same as other metals, but special stainless steel fabricating techniques are often recommended.
Advice on Machining Stainless Steel
Machining stainless steel can be relatively complicated because of decreased ductility and corrosion resistance in some grades of stainless steel, which increases the chance of chipping. Specialized steel melting processes have been developed to make machining stainless steel a little more efficient.
A few tips to improve the results of stainless steel machining include applying coolants or lubricants to the equipment, employing large machinery to disperse the heat, maintaining constant feeds and light cuts, utilizing chip breakers to make sure debris is repelled, choosing a machine that can reduce the level of vibration and always making sure the cutting edge is sharp.
Advice on Welding Stainless Steel
Welding is a common enough fabrication process, but once again, specialized stainless steel fabricating techniques must be used, especially for certain grades.
Thus, with austenitic stainless steel, one needs to take care as these versions can become sensitized and have inter-granular corrosion develop on thicker slabs of metal. If you need to weld thicker sheets, then you might want to go for a stainless steel that has a lower level of carbon.
Martensitic stainless steel is generally well-suited to welding but can develop cracks. Minimizing the chance of fractures appearing, the stainless steel much be pre-heated and post heated. Another option is to use additional filler rods made from austenitic stainless steel.
Ferritic stainless steel isn’t really suitable for welding, though certain versions might work in certain circumstances. Low ductility, sensitization and high grain growth can be dealt with by using fillers made from austenitic stainless steel or by making sure the material is heated after it has been welded.
Duplex stainless steel grades are quite efficient when it comes to welding. Some versions have a higher degree of nickel to make them stronger, more ductile and better resistant to corrosion.
Stainless steel is versatile and can certainly be subjected to most fabrication processes, including cutting, shearing, welding, bending, machining and more. However, in many cases, one has to take into account the type and grade of the stainless steel being used as well as ensuring that the proper stainless steel fabricating techniques are used to achieve the best results.
