High Temperature Hastelloy Studs Manufacturers

-- Steady & Reliable Manufacturer --

Introduction

Hastelloy Studs are highly specialized fasteners made from nickel-molybdenum-chromium superalloys, engineered for use in the most aggressive high-temperature and extreme corrosive environments, such as chemical processing, pulp and paper, and aerospace gas turbine components. Unlike stainless steel, Hastelloy maintains its mechanical strength and resists localized corrosion (pitting/crevice) even in the presence of strong acids and high chloride concentrations at elevated temperatures.

Extreme High Temperature, Strong Acid/Chlorides
Standard

ASTM B366 (Fittings), Special Bolt Specifications
Key Property

Creep and Stress-Corrosion Cracking Resistance
Testing Required

Extensive NDT (UT, MPI) and PMI (Positive Material Identification)

Applications

  • Chemical Processing Reactors: Bolting flanges exposed to sulfuric, hydrochloric, or hydrofluoric acids.

  • Flue Gas Desulfurization (FGD) Systems: Used in the highly corrosive environment of power plant scrubbers.

  • High-Temperature Furnace Components: Used in assemblies where temperatures exceed 500∘C.

  • Nuclear and Defense Industry: Specialized applications requiring absolute material integrity.

Advantages

  • Unmatched Corrosion Resistance: Superior performance in environments that would destroy stainless and alloy steels.

  • High Strength at Temperature: Retains excellent mechanical properties at extreme temperatures.

  • Full Traceability: Provided with complete Mill Test Reports (MTRs) and PMI certification.

  • Longevity: Significantly reduces downtime and replacement costs in critical processes.

Payment & Shipping

Due to the high material cost, payment for Hastelloy studs requires a mandatory L/C at Sight and a non-refundable tooling deposit for custom lengths. Each stud is individually marked, packaged in heavy-duty plastic sleeves, and shipped via insured, high-security freight, often with dedicated, project-specific crates.

FAQ

  • Q: Why is Hastelloy preferred over other high-nickel alloys?
  • A: Hastelloy is specifically engineered for its resistance to both localized corrosion (pitting) and stress-corrosion cracking in severe chemical environments, often performing better than standard Inconel or Monel grades when exposed to hot, concentrated acids.
  • Q: What special precautions must be taken during installation?
  • A: Due to the high alloy content, Hastelloy is highly prone to galling. It is mandatory to use specialized anti-seize lubricants (e.g., nickel-based) and carefully control the torque during installation to prevent thread seizure.
