Ss400 A36 Q235B Hr Cr Carbon Steel Coil - China Steel Pipe

Products Description. SS400 A36 Q235B HR CR Carbon Steel Coil. Hot rolled material is annealing in cold rolled annealing furnace and after pickling in acid. All mill rolls are grinded on precision grinding machine with proper chamfering after first shift operation. All sheets are pickled in different tanks and sheets are dried on brush Steel coil definition and classification from coil Cold-rolled sheet in coil form is produced by removing rust from hot-rolled sheet by "pickling" it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll. Cold-rolled steel is a more highly

A Quick Guide to Annealing:What is Annealed Metal?

Jun 30, 2020 · Sheet metals, such as cold rolled steel sheet and galvanized steel sheet, are annealed because the process of cold rolling creates too much hardness for further processing. Annealing restores their ductility and formability, which allows for further bending, punching , forming/stretching or cutting without cracking or losing dimensional stability.

We are the professional supplier who can meets all kinds of steel and fabrication requirements. If your required steel parts need cutting, welding, drilling, rolling, bending, forming, grinding, stamping and so on machining, we are ready to serve you.
