AISI 305 Characteristics

  • Proven metallurgical corrosion resistance across chemical, atmospheric, and marine media
  • Superior ductility and high toughness from cryogenic depths (-196°C) to elevated temperatures
  • Standard austenitic Face-Centered Cubic (FCC) lattice ensuring non-magnetic characteristics
  • Excellent weldability and compatibility with standard industrial TIG/MIG welding techniques
  • Comprehensive compliance with global ASTM, ASME, DIN, ISO, and BS bolting specifications

AISI 305 Applications

  • High-integrity industrial bolting (hex bolts, heavy hex nuts, stud bolts, tie rods)
  • Chemical and petrochemical process piping, pressure vessels, and heat exchanger flanges
  • Food, beverage, brewery, and dairy processing sanitary machinery and conveyor systems
  • Architectural structural facades, marine railings, coastal cladding, and glass wall spider bolts
  • Cryogenic storage tanks, LNG transport valves, and pharmaceutical cleanroom equipment
