EN 10263-3 Grade 17Cr3 – Optimized Annealing for Spheroidized Carbides and Precision Turning
The cold-upsettable steel 17 Cr 3 is suitable for the manufacture of screws and nuts (soft-annealed condition with pre- and/or post treatment) used in automobile, motor and equipment construction and in general engineering. The steel finds additional use, amongst other things, for bevel gears, gear shafts, valve spring plates (for example in case-hardened condition).
