Besides alloy steel grades, steel can be classified into a non-alloy steel grade. Some non-alloy steel grades are - Carbon steel, stainless steel and tool steel. Carbon steel account for 90% of the total steel population. They also have trace amount of alloy compounds. They can be further classified into low, medium and high carbon steels. The classification depends on the content of Carbon present in the steel. Low carbon steel contains up to 0.3% carbon content. Medium and high carbon steel contains between 0.3-0.6 and more than 0.6% of carbon respectively.

Stainless steel contains about 10 - 20% chromium as an alloying element. The addition of chromium makes steel resistant to corrosion. Based on their structure, Stainless steel can further be divided into three categories - Austenitic, Ferritic & Martensitic.

Chemically, Austenitic Stainless steel consists of 8% chromium, 8% nickel and less than 0.8% carbon. They are non-magnetic and Ferritic stainless steel consists of 12-17% chromium, less than 0.1% carbon, along with a trace amount of nickel. Some other alloying elements, such as molybdenum, aluminium, or titanium can be found in Ferritic steel. Ferritic stainless steel are magnetic and soft. Further these steels can be strengthened by cold working. Martensitic steels are magnetic and heat-treatable. They are used to produce cutting tools, knives, dental and surgical equipment. Martensitic steels consists of 11-17% chromium, up to 1.2% carbon and less than 0.4% nickel.

Tool Steels are used in manufacturing equipment because of their increased heat resistance and durability. The durability in tool steels is because it contains tungsten , molybdenum, cobalt and vanadium in varying amounts. They can further be classified depending on their applications and shapes. For example tubular long shaped products are used in the automotive and construction industries to manufacture wires, rods, pipes, bars, shapes and sections. Tool Steels are also used in the construction of piping materials like fittings, flanges, valves etc. Flat Products are used in the production of automotive parts, appliances, packaging, shipbuilding, and construction. They consist of products plates, sheets, coils, and strips. Although steels are considered as non-alloy steel grades, they do contain trace amounts of varying minerals or metals added to their chemical composition to enhance the quality of steel.
