Stainless Steel Coils are initially produced in slabs, which are then put through a conversion process using the Z mill, which converts the slab into a coil before further rolling. These wide coils are typically made at around 1250 mm (or a little wider) and are known as Mill Edge Coils.
A G Universal Limited produces a wide range of different types of stainless steel coils for construction and manufacturing industries. Stainless steel coils are one of the most required types of raw material in these industries. They are mainly used as material for those parts that require machining, welding, grinding, or polishing and where good corrosion resistance is also required. They are widely used in the production of appliances ranging from kitchen to engineering industry.
Stainless steel coils are strong, light in weight, flexible, resist corrosion, and require low maintenance. They easily meet the requirements of a range of design criteria. They are good in corrosive environments such as in paper, chemical industries and cryogenic services.
Stainless steel coils are manufactured in the following way:
- The rolling steel slabs are continuously heated in a reheat furnace at a certain high temperature ranging from 1100° C to 1300° C, which is known as the recrystallization temperature.
- They continuously run through heating and rolling mills to obtain a suitably coiled product.
- After hot rolling and coiling, the stainless steel coils are passed through the annealing and pickling lines to get pure, oxide free, with softer and brighter surface finish.
There are many types of stainless steel coils but the Grade 304 is the most standard type used alloy among them. Grade 304 is an authenticate chromium alloy, which is also known as an “18/8” stainless because it consists of 18% chromium and 8% nickel. The chromium content promotes the material’s considerable resistance to corrosion and oxidation effects.
Using stainless steel coils is a simple solution to corrosion. Stainless steel is the only option in systems requiring high temperatures, abrasive environments and extreme caustic chemical solution. Stainless steel coils are easy to fabricate, easy to clean, and aesthetically pleasing to eyes.
