309 Stainless Steel
Grade 309 Stainless Steel is used often for higher temperature applications. While its oxidation resistance surpasses that of alloy 310, its resistance to corrosion is equivalent to that of alloy 310. Alloy 309 is highly weldable and cold formable, although it does require stronger forming machines and continuously increasing pressure. Typical machining methods are used for stainless steel grade 309, but it is tougher and does tend to harden more quickly. Like 310 Stainless Steel, Grade 309 Stainless Steel has a high chromium and nickel content which grants excellent resistance to aqueous corrosion.
