The 200 series substitutes manganese for some of the nickel used in 300-series grades, reducing cost at the expense of some corrosion resistance. We manufacture welded tube in 200-series grades 201 and 202 — tell us your requirement and we'll quote it.
Weight %, maximum unless a range or minimum is shown. Balance is iron (or nickel, for the nickel-base alloys). Grades with a detailed guide link to their full page.
