DIN EN 10268
High-strength low-alloy steels
BILSTEIN’s micro-alloyed steels, which are in accordance with DIN EN 10268 standards, offer minimum yield strength levels from 260 to 420 MPa with excellent cold formability at all strength levels. This grade familiy is used wherever a component requires considerably higher yield and tensile strength levels than mild or unalloyed steels can provide. Additionally, using this higher grade steel means strip thickness can be reduced, lowering the weight and cost of the final product.
Compared to the high-strength construction steels once used as standard, these low-pearlite, micro-alloyed grades have a significantly reduced carbon content and therefore can be welded almost without exception using all standard techniques.
Upon request, we can also develop grades above standards with further restricted chemical analysis, compressed mechanical properties, or low earing properties.
Applications:
Automotive seat structures, automotive transmissions, car door, hood and trunk-lid structures, furniture hinges, window fittings, etc.
