1.8507 (DIN EN ISO 683-5 : 2021-08)	1.8507	DIN EN ISO 683-5 : 2021-08	Supersedes DIN EN 10085 : 2001-07	Valid	Germany	34CrAlMo5-10	The heat-treatable steel 34CrAlMo5-10 is applicated for hot steam fitting parts of high fatigue limit. Suitable for dimensions up to 80 mm. Components: valve spindles and plates Further applications: plunger, piston rods, grinding and milling machine spindles, measuring instruments The steels contains nitriding agents (Cr and Al) which contribute by the nitriding resp. nitrocarburization process with N resp. N and C to an increase of - case hardness - wear resistance - fatigue resistance and - corrosion resistance. Application for forged components: hardened, mechanically machined and thermochemically treated (e.g. nitriding). The steel with a higher Al-content shows a tendency to increased decarburization. The forged part requires sufficient machining allowances so that the finished component can be supplied to the nitriding process decarburization-free.
