Stainless Steel Capillary Tubes 321 Wst. 1.4541 UNS S32100:-

Specification:
ASTM A 269/A 213/ASME SA 213
N 10216-5/EN 10305
NACE MR0175/PED 97/23 EC

Maximum service temperature: 650°C / 1205°F

Alloy 321 stainless steel is a titanium-stabilized version of alloy 304, used in particular applications within the sensitizing temperature range. It’s resistance to sensitization, coupled with it higher strength, at high temperatures makes it suitable in application where alloy 304 will become sensitized, or where 304L has insufficient hot strength.

Characteristics

  • Excellent resistance to high-temperature corrosion
  • Excellent formability
  • Higher creep resistance
  • Good resistance for intergranular corrosion when expose in midly corrosive environments

Market applications:

  • Chemical & refineries
  • Power plants
  • Super heater and after burner parts  
  • Furnace components
