Description
IS X02Cr21Ni25Cu Round Bars
IS X02Cr21Ni25Cu Round Bars are high-alloy austenitic stainless steel round bars. The grade is characterized by high nickel, chromium and molybdenum content, along with copper addition, providing excellent resistance to aggressive and highly corrosive environments.
The grade contains approximately 19-23% chromium, 23-28% nickel, 4-5% molybdenum and 1-2% copper, while carbon is limited to 0.020% maximum. This chemistry gives X02Cr21Ni25Cu its strong corrosion-resistance characteristics.
Textron Steel and Alloys supplies IS X02Cr21Ni25Cu Round Bars for applications requiring excellent corrosion resistance, particularly in chemical processing, pollution-control and other demanding industrial environments.
