SS 347 & 347H Stud Bolts Supplier & Exporter

Aurum Overseas is a trusted manufacturer and global supplier of premium stainless steel fastening solutions engineered for industrial environments requiring excellent corrosion resistance, elevated temperature stability, and dependable long-term mechanical performance under demanding operating conditions. Our fastening products are widely supplied to refinery operators, petrochemical processing plants, power generation companies, thermal processing industries, EPC contractors, and heavy engineering manufacturers requiring certified fastening systems for critical industrial assemblies.

SS 347 and 347H Stud Bolts belong to the stabilized austenitic stainless steel family developed specifically for applications exposed to high temperatures, continuous thermal cycling, and corrosive industrial operating environments. These materials are niobium stabilized, allowing them to resist intergranular corrosion while maintaining excellent oxidation resistance and mechanical stability in applications where conventional stainless steel fasteners may experience reduced service life.

At Aurum Overseas, we manufacture and export certified industrial fastening products with complete inspection reports, dimensional verification, material traceability, and export documentation for industrial buyers worldwide.

What are SS 347 & 347H Stud Bolts?

SS 347 Stud Bolts and 347H Stud Bolts are fully threaded industrial fasteners manufactured from niobium stabilized austenitic stainless steel designed for pressure systems, flange assemblies, structural fastening systems, heat exchangers, and industrial process equipment exposed to elevated temperature service conditions. These fasteners are commonly installed with heavy hex nuts on both ends to provide balanced tightening force and secure assembly performance under demanding industrial loads.

The niobium stabilization in stainless steel 347 helps prevent chromium carbide precipitation during welding operations, improving resistance against intergranular corrosion in high-temperature industrial systems. Standard SS 347 Studs are commonly selected for corrosion resistance and thermal stability, while 347H Stud Bolts contain higher carbon content that improves creep strength and mechanical stability during prolonged elevated temperature exposure.

This material family is widely associated with ASTM A193 B8C Stud Bolts, commonly specified for pressure vessel assemblies, industrial piping systems, thermal processing equipment, and refinery infrastructure operating under high-temperature service conditions.

SS 347 & 347H Stud Bolts Specifications

Mechanical Properties of SS 347 & 347H Stud Fasteners

The stainless steel 347 family offers strong mechanical performance while maintaining oxidation resistance and structural stability in high-temperature industrial applications.

Chemical Composition of SS 347 & 347H Stud Material

The primary difference between 347 and 347H lies in carbon content, which influences long-term high-temperature mechanical stability and creep resistance.

Available Dimensions & Size Range of SS 347 Stud Bolts

We manufacture precision-engineered stud fastening solutions suitable for pressure piping systems, industrial flange assemblies, refinery equipment, thermal processing systems, and heavy engineering applications requiring dependable fastening performance.

Thread Options Available for Stainless Steel Stud Fasteners

SS 347 vs 347H Stud Bolts Comparison for Elevated Temperature Applications

Both grades provide excellent corrosion resistance and oxidation protection, but material selection often depends on operating temperature range and long-term exposure conditions.

For industrial applications requiring stabilized corrosion resistance and welding reliability, SS 347 Studs are commonly selected. Systems operating under prolonged elevated temperature exposure generally utilize 347H Stud Bolts because higher carbon improves creep strength and long-term structural performance. Buyers evaluating similar heat-resistant grades often compare SS 321 Studs and SS 310 Studs depending on engineering requirements.

Industries Using SS 347 Stud Fasteners
