  • Minimum tempering temperature 1200°F (650°C).
  • Full chemistry limits: confirm with current ASTM A193/A193M.
What sizes are available in ASTM A193 Grade B16 stud bolts?
  • Ex-stock 1/4 inch to 4 inch (M6 to M100).
  • Custom lengths cut to your drawing.
  • UNC up to 1 inch; 8UN above 1 inch.
How do A193 B16 hex bolts compare with B7 hex bolts?
  • A193 B16 Hex Bolts is Cr-Mo-V steel; B7 has no vanadium.
  • B16 is chosen for higher-temperature bolting service.
  • B7 is the cheaper general-purpose grade.
Where are A 193 B16 heavy hex bolts typically used?
  • Valve bonnets, flange joints and steam piping.
  • Power, refinery and petrochemical hot service lines.
  • Head dimensions supplied to ASME B18.2.1.
What is the difference between ASTM A193 and SA 193 Gr B16?
  • SA-193 is the ASME Code counterpart of ASTM A193.
  • Technical requirements are essentially identical.
  • Dual certification A193/SA-193 available on request.
What is the maximum service temperature for B16 bolts?
  • High-temperature bolting grade, commonly quoted to 1000-1100°F.
  • ASTM A193 sets material requirements, not a temperature limit.
  • Confirm the actual limit with the governing code (ASME B31.3 or BPVC Section II Part D).
Can A193 B16 threaded rods be cut to custom lengths?
  • Cut and chamfered to your drawing length.
  • Plain, black oxide, zinc plated, HDG or PTFE finishes.
  • Stock ships in 2-3 days; custom takes 2-3 weeks.
Are ASTM A 193 B16 anchor bolts available on order?
