Hot-dip galvanized micro-alloyed steels with high yield strength for cold forming

Steels according to DIN EN 10346 for cold forming and high strength

The DIN EN 10346 standard defines various types of steel specifically developed for applications with high requirements for strength and formability.

Bake-Hardening-Steel (B):
This type of steel exhibits an increase in yield strength after heat exposure at 170°C for 20 minutes. Bake-hardening steels are excellent for cold forming processes and are characterized by increased resistance to plastic deformation as well as improved dent resistance in the finished component. This makes them particularly suitable for applications where mechanical stresses occur after heat treatment.

Steel Without Interstitial Atoms (Y):
Also known as “Interstitial Free” (IF) steel, this type is designed to provide high mechanical strength and excellent suitability for cold forming. The microstructure, free of interstitial atoms, enhances r- and n-values, positively affecting formability and strength. Strength is achieved through solid solution strengthening.

Low and Micro-Alloyed Steel (LA):
Micro-alloyed steels achieve their high strength through the use of alloying elements such as niobium, titanium, and vanadium. These steels combine precipitation hardening and grain refinement, providing high mechanical resistance despite a reduced content of alloying elements. Alternatively, carbon-manganese concepts can also be applied to enhance strength.

Steels with High Yield Strength for Cold Forming:
These steels are classified according to their minimum yield strength and are particularly suitable for applications requiring high mechanical strength combined with good formability. They offer high durability and are ideal for complex forming processes.

Ordering Information According to DIN EN 10346:
When requesting and ordering hot-dip coated steels, specific details must be provided to ensure the desired material properties. These include the quantity, product form (coil, sheet, etc.), nominal dimensions, steel designation or material number, coating types, and surface treatments. The type of desired surface treatment (e.g., chemically passivated, oiled, or phosphated) must also be specified.

These steel types provide an ideal solution for industrial applications where high strength and cold formability are required, such as in automotive manufacturing or the production of complex components.
