Bright Annealing is a process of heating, soaking and controlled cooling of coil in a non-oxidizing atmosphere. Metallurgically, the annealing process relieves the stresses developed by Cold Rolling and renders the strip soft and restores its ductility and formability. Solution Annealing Solution annealing is the heat treatment most frequently specified for stainless steels. The main objective is to dissolve the phases that have precipitated during the thermo mechanical processing of the material, especially the chromium-rich carbides. Bright annealing lines use 100% inert atmosphere, resulting in a clean and bright surface of the strip.

pickling removes the annealing oxides and mill contaminations like oils and unwanted metallic and non-metallic particles. Removal of Chromium depleted zone STAINLESS STEEL HNO3 / HF CHROMIUM-DEPLETED ZONE SCALE Mechanism of pickling, HNO3 / HF Pickling is the final step in making stainless steel corrosion resistant!
Tension levelling consists of subjecting the strip of sheet metal to a traction force sufficient to exceed the yield stress of the fibers making up the material, combining this lengthening with simultaneous deformation of the strip caused by intermeshing of the levelling rolls.
Slitting is a shearing process in which the width of an original, or master, coil is reduced into multiple narrower coils to customize width of strips to cater to the diversified needs of customers. At Jindal metals & alloys ltd, We can slit as narrow as 3.5 mm width.
Burrs are sharp edges resulting from cutting operations. Although usually small in size, burrs can cause assembly problems, interfere with fluid flow, and are a common cause of worker injury. Burrs can also cause increased stresses and subsequent fatigue failure of the part. Burr is removed through mechanical process is called as deburring. Many deburred materials are used in industry for their application for finishing manufactured parts.
For many components and exposed parts, a skived round edge provides greatly improved cycle life and a safer edge with chatter and burr eliminated meaning smoother uncoiling and safer handling for end users as well as employees.
Degreasing is a process where dust particles, oils, carbon and other contamination is removed from a surface. Degreasing is an essential part of the production process.
Oscillating refers to the winding, end to end, of several ribbon wound steel coils on a drum. The combination of welding several coils in this manner creates one larger and heavier coil than a ribbon wound coil. Oscillating can be accomplished by winding slit coil or oscillating after the edging process. Sometimes, oscillating is called traverse winding. Each wrap winds alongside the previous wrap. Oscillating is typically done on finished steel widths of 2 inches or less.
Steel that is oscillate wound creates a finished coil that is up to ten times the length of a ribbon wound coil. When using oscillating coils in a stamping operation, loading times are reduced by up to 100 %. In addition, oscillating creates a better more solid package for shipping. Truckload quantities of traverse or oscillate coils contain skids to load. Oscillating, particularly after being run through an edging process, assures a camber free tightly wound coil such as Single Strip.
