The history of steel industry began in the late 1850s, but since then steel has been basic to the world's industrial economy. Steel is an alloy that consists mostly of iron and has carbon content between 0.2% and 2.1% by weight, depending on the grade.

Stainless Steel is also known as Inox Steel. It is defined as a steel alloy with a minimum of 10.5[1] or 11% chromium content by mass. Stainless steel does not stain, corrode, or rust as easily as ordinary steel Stainless steels resistance to corrosion and staining, low maintenance and familiar luster make it an ideal material for many applications like It is used in making sheets, plates, bars, wire, and tubing to be used in cookware, cutlery, hardware, surgical instruments and  industrial equipment.

Mild steel  is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials
