Duplex steels are a tougher breed of steels than the usual 300 series austenitic types, with about twice the comparative strength. Duplex is usually a mix of both austenite and ferrite structures, resulting in improved engineering properties than the 300 series. But where pure ferrite grades have reduced corrosion resistance, Duplex steels have increased resistance to localized corrosion over 300 series steels; particularly pitting, crevice corrosion, and stress corrosion cracking. Duplex grades are characterized by high chromium (19–32%) and molybdenum (up to 5%) and lower nickel contents than 300 series austenitic steels. read more
Stainless steel is the generic name for a number of different steels used primarily because of their corrosion resistance. All stainless steels share a minimum percentage of 10.5% chromium. Chromium is always the deciding factor, although other elements, particularly nickel and molybdenum, are added to improve corrosion resistance. read more
Carbon steel is steel whose main alloying constituent is carbon, with iron making up the remainder, and other elements present in quantities too small to affect the properties. The only other alloying elements allowed in plain-carbon steel are manganese (1.65% max), silicon (0.60% max), and copper (0.60% max); there is no specified minimum content of these or any other alloying metal. read more
There are many other alloys, and although we do not stock all grades we are able to source many of them to meet your needs. We can provide other ferritic-austenitic (duplex) grades such as F50, F51 (2205), and F52, as well as high nickel alloys such as Inconel 625, Incoloy 825, and Hastelloy C-276, and rare stainless steel grades such as 304H. Our network of mills throughout the US and offshore guarantees that cost and delivery are always competitive. read more
