310 Stainless Steel
Alloy 310 / SS310 stainless is an austenitic stainless steel with a high nickel and chromium content which makes the alloy heat resistant with excellent resistance to oxidation under mildly cyclic conditions through 2000ºF. Its high chromium and nickel contents provide comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic alloys like alloy 304. Stainless alloy 310 is often used at cryogenic temperatures, with excellent toughness to -450°F.

Corrosion Resistance
Refer to NACE (National Association of Corrosion Engineers) for recommendations. Standard Wire Finishes Extra Clean: (XC) Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled” Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications Soap (round wire only): Soap is used as a lubricant in the drawing process andis not removed. It acts as a lubricant during customer part forming operation. A soap finish is available in tempered products. Plated: Many plating options are available. Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests
Welding
For best results refer to: SSINA’s “Welding of Stainless Steels and Other Joining Methods”.
Forging
Heat the 310 stainless slowly and uniformly throughout the section to 1100-1230°C. Reheat as necessary and avoid working below 1000°C..
