SPECIFICATIONS:
ASTM A240, ASME SA240,
EN10028-7, JIS G 4304, GB/T4237
DESCRIPTION:
Alloy 309/309S and Alloy 310/310S austenitic stainless steels are typically used for elevated temperature applications. Their 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 Alloy 304.

Their 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 Alloy 304.
DESIGN FEATURES:
• Austenitic stainless steel with excellent high
temperature oxidation resistance.
• Good for continuous exposure to 2100 deg.F. intermittent service to 1900 deg.F.
• Better elevated temperature creep strength than the 18-8 grades.
• Good resistance to both carburizing and reducing environments.
• General corrosion resistance better than Types 304 and 309.
• May be susceptible to chloride stress corrosion cracking.
• Availability.
• Ease of fabrication.
