Mittal Steel USA offers a variety of mild and drawing quality steels with a range of formability and coating conditions.

Product Characteristics

Mittal Steel USA offers a wide range of Mild steels. Depending on the formability requirements the appropriate sheet steel grade may be selected. Steel grades range from Commercial Steel (CS), which have the reasonable formability to grades like Extra Deep Drawing Steel Plus (EDDS Plus) which offers superior formability.

All of these grades are low carbon grades. Some of the highly formable steels contain ultra-low levels of carbon and are fully stabilized with microalloying elements like titanium and/or niobium. These steels are also commonly known as interstitial-free steels, i.e. these steels have no free, interstitially available, carbon or nitrogen.

Application

These steels are the most widely used grades in the automotive industry. They offer excellent formability and can be used for a range of parts from simple small brackets to complicated shapes like wheelhouses and floor-pans. The lower strength of these steels, can limit their applications where dent resistance, durability and high strength requirements are essential. These grades have excellent manufacturability and can be easily joined using conventional welding techniques. Except for CS, all others grades are available as exposed quality steels, also.
