In environments where failure is not an option, every component must perform. The integrity of your assembly relies on the strength and compatibility of its most fundamental parts: the bolts and the nuts. RAYCHIN LIMITED provides the perfect synergistic partnership with our premium Hastelloy Bolts and Hastelloy Nuts, engineered to deliver unmatched corrosion resistance and mechanical reliability in the harshest conditions.

Hastelloy Bolts: The Core of Structural Integrity

Our Hastelloy Bolts are designed to be the robust backbone of your critical connections. Manufactured from high-performance alloys like Hastelloy C276 Bolts and Hastelloy B2 Bolts, they offer exceptional resistance to pitting, stress corrosion cracking, and a wide range of aggressive chemicals.

· Key Applications:

· Securing flanges in chemical and petrochemical processing reactors.

· Structural fastening in offshore oil & gas platforms and marine equipment.

· Assembling pollution control units like Flue Gas Desulfurization (FGD) systems.

· Critical connections in pulp and paper mill digesters.

· Critical Considerations:

· Mechanical Properties: Ensuring the bolt grade (e.g., ASTM A193 B6) meets the required tensile and yield strength for the application's pressure and load.

· Corrosive Media: Selecting the correct Hastelloy grade (C276 for oxidizing chlorides, B2 for reducing environments) is paramount to prevent premature failure.

· Temperature & Stress: Accounting for thermal expansion and stress relaxation at high temperatures to maintain clamp load.

Hastelloy Nuts: The Essential Partner for a Secure Assembly

A bolt is only as strong as the nut it threads into. Our Hastelloy Nuts are precision-engineered to provide a perfect, secure mate for our bolts. We offer a full range, including Hastelloy C276 Nuts and Hastelloy B2 Nuts, ensuring complete material compatibility and performance.

· Key Applications:

· Used in conjunction with Hastelloy Stud Bolts for high-pressure vessel closures and heat exchangers.

· Essential for maintaining tension in pump casings, valve bodies, and pipeline systems.

· Providing reliable threaded connections in pharmaceutical and food processing equipment where purity is critical.

· Critical Considerations:

· Galling Resistance: Hastelloy alloys are prone to galling. Our nuts are designed and finished to minimize this risk, ensuring smooth installation and disassembly.

· Hardness Matching: The nut hardness is carefully controlled to be slightly different from the bolt to prevent thread seizure and ensure the bolt fails before the nut threads strip—a key safety feature.

· Dimensional Accuracy: Precision threads are crucial for achieving the correct preload and preventing leakage in sealed systems.
