High Quality Steel

Steel 15 CDV 6 (SCV - 1.7734)

alloyed steel with excellent mechanical qualities
- high endurance
- high torsional strength and elasticity
- high yield point

lightweight pipes and profiles with smaller diameter and thickness can be produced

- welding without pre-warming
- elasticity

steel developed for use in airplane building also applicable to other high-speed applications such as racing automobiles, etc..
