Why Stainless steel 321?

More information on ss 321/321H

UNS S32100(Stainless steel 321) is really titanium stabilizes austentic steel with best corrosion resistance. It has outstanding amount of resistance to intergranular deterioration (corrosion) after it contact with temperatures in the chromium carbide precipitation range of 800-1500°F. stainless steel 321(UNS S32100) IS Compared with ss 304(UNS S30400) With higher amount of nickel and stabilized with titanium . titanium which does preferentially response to co2(carbon) in steel and prevent destruction of Cr(Chromium) Carbides at grain boundries .Stainless steel 321(UNS S32100) generally response Properly to hardening by cold working . It has good welding characteristics.Furthermore, it possesses very good lower temp toughness.

Grade ss 321 and ss 347 are austenitic steel i.e austenitic 18/8 steel(Grade ss 304) which is stabilized by titanium . The key feature of this grades are that they are not sensitive to intergranular corrosion after heating process with in proper precipitation range i.e. 425-850°C.Stainless steel 321H( UNS S32109) is modification of stainless steel 321(UNS S32100) With higher carbon in it . Which helps to provide better high temps strength. Stainless steel 321( UNS S32100) is not recommended as welding consumable as titanium does not get transfer will across high temps arc. Stainless steel 347 (UNS S34700) Is mostly used for welding 321. Grade Stainless steel is commonly used as parent plate material.

Both ss 321 and 347 have excellent features of forming and welding . and are be easily brake or rolled . Stainless steel 321 does not polish well so it is not recommended for decorative or furnishing applications

Key Properties of SS 321

ss 321 Buttweld and ss 321H Buttweld fittings

  • ss 321 and 321H Can be easily welded and proccessed
  • ss 321 can me exposed to maximum temperature of scaling to 2100-2300 °F and are suggested for Bending, Forging, upsetting and other hot process .
  • ss 321 can not be suitable for work below 1700°F
  • ss 321 should be anneled and water quenched after maximum corrosion resistance
  • ss 321 is Ductile and easily forms
  • ss 321 is welded by common standard process and post weld heat treatment is not required.
  • SS 321 hardening is similar to ss 304

Other Properties

321/321H Buttweld fittings

  • Cold Working – 321 are very ductile and can be easily cold world by deep drawing, Forging, upsetting, bending etc . It may require immediate annealing. High Hardness and strength is achieved should cold working
  • Formability – 321 & 321H is highly formability due to its combination of lower strength and shapes
  • Weldability – Stainless steel is considered as weldable by common fusion and resistance technique both with and without filler metals. SS 321 can be welded by ss 347 rods and Electrodes.
  • Corrosion Resistance – SS 321 & 321H is compared with ss 304 grade in annealed condition. General resistance of ss 321 is affected if heated for long period of time .It has been developed for applications. Where the unstabilized Chromium-nickel steel,such as stainless steel 304 would be susceptible to intergranular corrosion/
  • Heat Theatment – SS 321 is heat to 950-1120°C and rapidly cooled for maximum corrosion resistance. Ss 321 can not be hardened by heat treatment
