DIN 1654-5 Grade X6Cr17: Cold-Drawn, Annealed Steel with Spheroidized Carbides for Superior Cold‑Forming
The steel X6Cr17 is well suited for cold-forming. The strain hardening inclination is significantly lower than that of stainless austenitic steels and is about equal to that of carbon steel. The ferritic, 17%-Cr steel is used to treat corrosion occurances through water, steam, weak acids, as well as solutions and oxidizing acids (for example nitric acid). Used for screws and molded parts. Temperature of use: up to 300 degrees C.
