HR660Y760T-CP-GI: Hot-rolled high-strength bainitic steel in a hot-dip galvanized version

13.05.2026 | Salzgitter Flachstahl GmbH

This high-tech bainitic hot-rolled steel is a multiphase steel that is also available in a hot-dip galvanized version for use in chassis and body components.
Are you looking for better corrosion protection for your chassis? Then choose our hot-dip galvanized HR660Y760T-CP-GI. A zinc coating can protect against corrosion, especially on chassis components that are exposed to direct stone chips from the road. Thanks to precise process control during the hot-dip galvanizing process, the hot-rolled strip retains its usual beneficial properties.

We offer you a material that combines reliable formability with good corrosion protection. 

The material is already being used in the production of premium vehicles.

Due to its technological properties, reliable formability, and corrosion resistance, the complex-phase steel HR660Y760T-CP-GI is particularly well-suited for use in chassis components.

Why is this material particularly optimal for this type of component?

  • Premium hot-rolled steel product with high-quality hot-dip galvanizing on both sides, providing excellent cathodic corrosion protection
  • Increased hole expansion in the xpand® variant for particularly low susceptibility to edge cracking
  • Reliable manufacturing of highly complex component geometries while maintaining high strength
  • Significant potential for component integration
  • High fatigue strength of the manufactured chassis components
  • Potential for lightweight construction through reduced sheet thickness and material-appropriate design

For more information on HR660Y760T-CP-GI, please visit our product page or refer to our material data sheet. The specifications correspond to the HR660Y760T-CP-GI grade as defined by the VDA 239-100 standard. The hole expansion value of at least 40% or, in another variant, at least 50% is guaranteed for the grades HR660Y760T-CP-GI xpand®40 and HR660Y760T-CP-GI xpand®50.
