What is a Stainless Steel Coil?
Stainless steel coils are categorized according to its production process including hot and cold-rolled. These are characterized by their smooth surface, polishable, heat resistance, and more.
Different Classifications of Stainless Steel Coil According to Its Material
Austenitic structured ss coils contains 18% chromium, 0.1% carbon, and 8-25% nickel. It has characteristics such as low strength, plasticity, and high toughness.
Stainless steel coils that belong to the martensitic classification have adjustable mechanical properties by appropriate heat treatment.
Duplex
Duplex stainless steel sheet rolls are composed of half the structure of ferrite and austenitic. It is composed of 18-28% chromium and 3-10% nickel. These materials also contain Ti, Nb, Mo, Si, N, and Cu elements.
The ferritic stainless steel coils have a structure like a body-centered cubic crystal. It is composed of 15-30% chromium and does not contain elements such as nickel. These materials are characterized by excellent corrosion resistance, oxidation resistance, small expansion coefficient, and thermal conductivity.
How Stainless Steel Coils are Produced?
The stainless steel coils are produced using a wide range of advanced technology and raw materials. There are different methods that are used for manufacturing ss coils such as extrusion, cold rolling, and hot rolling. Several factors that affect the manufacturing process of this material include width, length, diameter, and thickness.
Hot Rolling Process. In this process, the raw materials are melted using a high temperature. Then, it is shaped into different forms with a variety of hardness levels. The hot rolling process allows producing stainless steel coils with uniform shape, size, and thickness.
Cold Rolling Process. The cold-rolling process involves the use of controlled conditions to maintain the stainless steel coil quality during every manufacturing stage. In this process, the raw materials will undergo different processing including roughing pass, semi-finishing pass, and finishing pass. This manufacturing method allows the production of ss coils with excellent surface finish and dimensional accuracy.
Stainless Steel Coil Edge Options
Mill Edges. This edge is non-trimmed after annealing and a hot/cold rolling process. It is characterized by irregular pinhole lines with diameters ranging from 10mm to 15mm.
Slit Edge. Irregular pinhole lines are trimmed using a slitting machine.
