Mill′s test certificate: EN 10204/3.1 with all relevant data reg. chem. composition, mech. properties and results of testing. | Application: Alloyed heat treatable steel with a typical tensile strength of 1100 -1300 N Used 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. |
