Description

X 2 CrNi 18 10 is an austenitic CrNi steel which, due to the added nitrogen alloy, possesses an increased yield strength which also persist in higher temperatures. It is suitable for the chemical equipment construction because of its resistance to nitric acid. The steel is well suited for cold-forming and can undergo high-gloss polishing. It is used for screws, nuts and molded parts at temperatures from -270 up to 400 degrees C.
