Heat Treatment:


Application:
Alloyed heat treatable steel with a typical tensile strength of 1100 -1300 N/mUsed for highly stressed components, where the combination of high strength with tenaciousness is of utmost importance. High cold formability: Parts of different shape can be manufactured, a favorable fibering for stress, a very good surface condition and an high dimensional accuracy. When cold formed the smooth surface leads to an increased fatigue and vibratory strength.
