HCT1180G2 is a cold-rolled multi-phase steel specified according to the DIN EN 10338 standard. Due to its outstanding mechanical properties and high strength, it is widely used in various industrial applications, particularly in the automotive industry. This type of steel combines different microstructures, such as ferrite, martensite, bainite, and retained austenite, to achieve an optimal balance between strength and ductility.

HCT1180G2 is characterized by its special microstructural composition. The multi-phase structure mainly consists of martensite and bainite within a ferrite matrix. This combination allows for a high tensile strength of up to 1180 MPa without sacrificing elongation. The martensitic component provides the necessary hardness and strength, while ferrite and bainite contribute to the required toughness and formability.

Through controlled cooling and targeted heat treatment during the manufacturing process, a fine microstructure is achieved that optimizes both the mechanical properties and the workability of the steel.

The exceptional properties of HCT1180G2 make it particularly suitable for use in safety-relevant components of the automotive industry. These include bumpers, door reinforcements, and other structural parts that require high strength while ensuring good energy absorption and elongation. Additionally, the steel is used in the production of demanding construction and structural materials, where its mechanical advantages are fully utilized.

HCT1180G2 offers numerous advantages over traditional steel grades. Its high strength enables the construction of thinner and lighter components without compromising safety and stability. This contributes to reduced vehicle weight, resulting in improved fuel efficiency and lower CO₂ emissions. Furthermore, the high ductility enhances crash safety, as the steel can undergo significant deformation before breaking.

The production and processing of HCT1180G2 strictly adhere to the requirements of DIN EN 10338. This standard ensures that the steel meets consistent quality and performance standards. Additionally, HCT1180G2 can be electro-galvanized according to DIN EN 10152 to provide additional corrosion protection. This galvanizing method ensures a uniform zinc coating, further increasing the durability of the steel and protecting it from environmental influences.

HCT1180G2 is a highly advanced cold-rolled multi-phase steel that stands out due to its unique microstructure and outstanding mechanical properties. The combination of high strength, ductility, and formability makes it a preferred choice in the automotive industry and other demanding applications. Compliance with strict standards such as DIN EN 10338 and the option for additional electro-galvanization according to DIN EN 10152 guarantee consistently high quality and long-lasting performance for this innovative steel.
