Advantages of Stainless Steel 347H Stud Bolts

These flexible stud bolt fittings offer numerous benefits for various industrial applications.

• High-Temperature Strength: Stainless Steel 347H has higher carbon content, and hence it has better tensile and yield strength in high temperature applications; hence, it is used where mechanical properties are required in thermal conditions.
• Improved Creep Resistance: The 347H has a better creep resistance than the regular 347 grade of stainless steel, making it suitable for high-temperature applications where it will not deform due to heat.
• Excellent Oxidation Resistance: It also possesses fairly good high temperature oxidation resistance, which is important in avoiding oxidation and scaling on the stud bolts during service.
• Resistance to Intergranular Corrosion: Like the regular 347, Stainless Steel 347H is not prone to intergranular corrosion due to columbium (niobium), which inhibits the formation of chromium carbides.
• Good Weldability: Welding: Welding of Stainless Steel 347H can be done by using the conventional methods of welding. This makes it possible for stud bolts to be applied in various assemblies without stressing on their performance.
• Enhanced Durability: Stainless Steel 347H is tough and has high corrosion resistance and therefore suitable for use in harsh environments.

The Stainless Steel 347H Stud Bolts offer several advantages that make them suitable for industrial and commercial applications.
