Stainless Steel 347/347H Nuts - FAQs

Stainless Steel 347 and 347H Nuts are fasteners made from a stabilized austenitic stainless steel that offers excellent corrosion resistance, even in high-temperature environments.

Stainless Steel 347H Nuts are the high-carbon version of 347 Nuts, providing enhanced high-temperature strength and creep resistance, making them suitable for more demanding applications.

These nuts find extensive use in industries like petrochemicals, chemical processing, oil and gas, power generation, aerospace, and more, due to their resistance to corrosion and high temperatures.

They are commonly used in flange connections, pressure vessels, heat exchangers, aircraft exhaust manifolds, and other high-temperature environments requiring corrosion resistance.

Yes, the high-temperature stability of these nuts makes them suitable for applications in temperatures ranging from cryogenic to elevated levels.

Ensure accurate torque values and proper threading techniques during installation to prevent over-tightening, which could damage the nuts or the connected components.

Yes, many manufacturers, including GIC Fasteners, offer customization options such as size, thread type, and coatings to match specific project requirements.

Yes, the alloy's resistance to corrosive acids and sulfurous gases makes it suitable for applications involving acids such as acetic acid, sulfuric acid, and more.

GIC Fasteners typically provides nuts that meet ASTM and ASME standards. Additionally, they might offer certifications like ISO 9001:2015 to ensure quality control and consistency.
