This steel is subjected to a special heat treatment, which mainly produces a two-phase structure. Ferrite, which can impart formability, represents one phase, while martensite, which is responsible for strength, represents the other phase. Bainite may also be present as a complementary phase.

The main alloying elements of HSLA steel include carbon, manganese, molybdenum, chromium and nickel. The nickel varies according to different HSLA steel grades. The proportion and ratio of these elements all play a crucial role in the performance of HSLA steel.

complex phase steel is a commonly used steel for complex shapes that absorbs energy and it is highly resistant to various kinds of corrosion.

Hot-formed steel is widely developed for parts made by direct or indirect hot forming in the automotive industry.

Martensitic steel helps improve collision resistance and provides reliable guarantees for lightweight design and cost-effective production in the automotive industry. Docol is one of the cold-rolled high-strength steels on the market and has become an ideal material for applications such as side impact beams, bumpers, and structural components in the automotive industry.
