316L is recommended when the presence of carbide precipitation ranges cannot be avoided or when post-weld annealing is not an expected result. 316 stainless steel alloy is commonly used for bellows, instrument diaphragms, exhaust vessels, filters, seals, and chemical equipment.
Alloy 316 is a durable stainless steel with exceptional temperature tensile, creep, stress and fracture capabilities. 316, as opposed to 302, is more adapted to atmospheric and mild conditions. In the welded condition, 316 is susceptible to intergranular corrosion. Under certain conditions, 316 can resist dilute solutions; on the other hand, within some acids, 316 alloy is weaker compared to 304.
304 stainless steel can be used in the welding process due to the fact that it contains lower levels of carbon compared to 302 stainless steel, which allows the alloy to effectively perform carbon precipitation. 304 alloy is commonly used for control diaphragms, tubing, ferrules, gaskets, straps, and metal hoses. During the annealing process, 304 is slightly weaker compared to 302 due to the reduced carbon content. 304L possesses less carbon than 304, is active in the welded state, and has no threat of intergranular corrosion.
302 stainless steel offers users the best of both worlds, providing deep drawing and stretching capabilities. 302 alloy’s corrosion resistance makes it a smart choice for those looking for stainless steel help in the food, dairy and chemical industries. Other common applications include use in springs and stamping processes, bellows, springs, laminate joints, camera shutters, thermostats, diaphragms and gaskets.
