Description

In the production of steel products, steel is molded and reshaped with different machinery at different temperatures.  One process is steel rolling, which involves metal stock passing through a pair of rolls.  Rolling produces flat steel sheets of a specific thickness, and the process is classified according to the temperature at which the metal is rolled.  If the temperature of the metal is above its recrystallization temperature, or the temperature at which the grain structure of the metal can be altered, then the process is termed as hot rolling.  If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling.

Like cold rolling, cold drawing is performed at room temperature, but instead of producing a flat object like a coke can, cold drawing makes steel into the form of a wire like the spokes of a wheel or a paper clip.  To start the process, Steel is usual hammered and rolled so that it can be fit through a die; a tool that turns the steel mass into a wire.  The room temperature steel is pulled through the die which reshapes it into a thinner shape while maintaining the same volume.  It is similar to the idea of syrup flowing out of a bottle through a tube in that it changes shape but not volume, but instead of squeezing the metal, it is pulled out.  In order to get the wire down to the right diameter, it usually requires more than one pass through different dies.

Chemical Compostion

Usage/Applications

Channel Steel is usually used for building structure, vehicle manufacturing and other industrial structure and often used with i beam.

In details,  the channel steel belongs to carbon structural steel which is applied to in the field of construction and machinery. The channel steel  is usually used for arch-itechtural structure, and they could be welded in order to support or hang a vari-ety of facilities. They are also usually used in combination with I beam. Generally,the channel steel must possess perfect welding property, riveting property and mechanical property and so on.

Q3: Can stainless steel rust?

A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q4: What makes stainless steel stainless?

A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
