Typical Applications:
Collector rings, airplane exhaust stacks, annealing box covers, stainless steel flanges, stainless steel pipe fittings, jet engineparts,expansion joints, stainless steel tubes, stainless steel bars, stainless steel angle bars flexible metal hose and bellows.
Processing:
Annealing: Heat slowly to 1500 -1650°F, cool to 1100°F in furnace, air cool. Process Annealing: Heat to 1350 -1450°F, air cool. Hardening: Heat to 1700 – 1850°F, air cool or oil quench. Follow by stress-relief or temper. Stress Relieving: Heat at 300 – 800°F for 1 to 2 hours, air cool.
Tempering:
Heat to 1100 – 1400°F for 1 to 4 hours, air cool.
Forming:
Type 410 Stainless Steel has reasonably good cold working properties and can be moderately drawn and formed in the annealed condition.
Welding:
The martensitic alloys have limited weldability due to their hardenability. Corrosion: Type 410 Stainless Steel provides good corrosion resistance to air, water and some chemicals. It shows satisfactory resistance to nitric acid, concentrated sulfuric acid, dilute acetic acid and naphtha.
