Fittings made from stainless steel scrap go through a series of steps to be processed. This includes melting, refining, shaping, and finishing. The process starts with collecting and sorting stainless steel scrap from different sources like manufacturing waste, construction leftovers, and discarded products.
After the stainless steel scrap is collected, it is sent to a scrap yard for a thorough inspection and sorting process. This is to remove any impurities or contaminants mixed with the scrap. The sorted scrap is then transported to a stainless steel mill or foundry where it is melted down in a large furnace.
During the melting process, the scrap is heated to extremely high temperatures, usually between 1,500 and 1,800 degrees Celsius. This converts the scrap into molten stainless steel. The molten stainless steel is then refined to adjust its composition and remove any remaining impurities. This refining process ensures that the final product meets the required specifications for strength, corrosion resistance, and other desired properties.
Once the molten stainless steel is refined, it is poured into molds or cast into specific shapes depending on the desired fittings. Various casting methods like sand casting, investment casting, or continuous casting can be used. The choice of casting method depends on factors such as the complexity of the fitting design, production volume, and cost considerations.
After casting, the fittings undergo further processing to enhance their mechanical properties and appearance. Heat treatment optimizes the fittings' strength, hardness, and resistance to corrosion by subjecting them to controlled heating and cooling cycles. Machining is performed to achieve the desired dimensions and surface finishes, which can involve processes like drilling, turning, milling, or grinding. Surface treatment, such as polishing or electroplating, may also be applied for aesthetic appeal and additional corrosion protection.
Finally, the finished fittings are inspected to ensure they meet quality standards. This includes dimensional checks, visual inspection, and non-destructive testing methods like ultrasonic or X-ray examination. Once the fittings pass inspection, they are packaged, stored, and distributed for use in various industries like construction, plumbing, automotive, and manufacturing.

Stainless steel scrap is typically processed into fittings through a multi-step procedure that includes sorting, melting, refining, casting, and machining. First, the scrap is sorted and separated based on its composition and size. Then, it is melted in a furnace at high temperatures to form molten stainless steel. This molten steel is then refined to remove impurities and achieve the desired chemical composition. Next, the refined steel is cast into molds to create solid shapes, such as bars or billets. Finally, these castings are machined and shaped into fittings, which may involve processes like cutting, drilling, threading, and polishing.
