Product Description

Stainless Steel - Grade 309
Grade 309 is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high temperature strength and creep resistance. The lower nickel content of SX309 improves resistance to sulphur attack at high temperatures. It is tough and ductile, and can be readily fabricated and machined.
Sheet Thickness: 0.05mm and above
Typical Applications
Grade 309/309S is used exclusively for its high temperature oxidation resistance. It is common for Grade 309, 310 and 321 to be used in the same piece of equipment in the various temperature regions.

Thermal Processing
1.    Annealing. Heat between 1 050℃ and 1 150℃ and water quench. This treatment ensures that all carbides are in solution.
2.    Stress Relieving 250-400℃ for 1 hour.
3.    Hot Working
Initial forging and pressure                            1150-1 200℃
Finishing temperature                                     1000℃
Note: Soaking times to ensure uniformity of temperature are up to 12 times that required for mild and carbon steels.
