Its high yield strength combined with excellent bending workability makes it perfect for forming and roll forming applications. This versatile steel is available in cold-rolled (CR), galvanized (GI), and galvannealed (GA) products.
Applications: Structural parts of automobile vehicles that require high impact safety measures, such as sill side panels.

Electrogalvanized –
Galvanized – YES
Galvannealed – YES
1180CP-HE
1180CP-HE steel boasts higher elongation than 1180CP due to the addition of residual austenite. By incorporating this residual austenite into the CP steel matrix, which consists of ferrite, bainite, and martensite, the TRIP effect is leveraged to enhance elongation.
Applications: Structural parts of automobile vehicles that require high impact safety measures, such as sill side panels.

MARTensitic Steel (MART)
This steel features a martensite matrix with traces of bainite or ferrite, offering the highest tensile strength among all carbon steels, albeit with very low ductility. Rapid cooling followed by precise tempering can significantly enhance its yield strength.
1300MART
1300MART steel offers an impressive tensile strength exceeding 1,300 MPa and a yield strength of 1,000 MPa. Known for its high strength and limited ductility, it is favored for roll forming applications and as structural members to resist car body deformation upon impact. Available products encompass cold-rolled (CR) and galvanized (GI) variants.
Applications: Impact members of automobile vehicles that require high impact toughness, such as side the sill outers and bumper beams
1470MART
1470MART steel boasts a robust tensile strength surpassing 1,470 MPa and a yield strength of 1,050 MPa. Enhanced with additional alloy elements compared to 1300MART, it prioritizes superior impact safety. This steel is ideal for structural components that safeguard against car body deformation during collisions. Available in both cold-rolled (CR) and galvanized (GI) forms.
Applications: Impact members of automobile vehicles that require high impact toughness, such as side the sill outers and bumper beams
