Description	1.4574 / Alloy PH 15-7 Mo® is an austenitic chromium-nickel stainless steel with molybdenum and aluminum addition.

Special properties	Due to the existing molybdenum content of the stainless steel 1.4532 against the stainless steel 1.4568, the protection of the stainless steel increased before reducing acids and chloride-containing pleas which occur in river water among others. The resistance to pitting and crevice corrosion is dependent material-side on their content of chromium and molybdenum. Due to the content of molybdenum and thereby resulting nickel - molybdenum alloy increases with the 1.4532 resistance to corrosion (eg in the stress corrosion crackin
