Stainless Steel 347H Welded Pipes

In industries where high temperatures, corrosion resistance, and mechanical strength are paramount, the choice of materials becomes crucial. Stainless Steel 347H welded pipes stand out as an exceptional solution, offering a unique combination of properties that make them ideal for a wide range of applications. Whether you’re in the petrochemical, aerospace, or power generation sector, these pipes provide the reliability and performance you need.

Product Overview

Stainless Steel 347H is a high-carbon version of Stainless Steel 347, which itself is a niobium-stabilized austenitic stainless steel. The addition of niobium enhances its resistance to intergranular corrosion, particularly in high-temperature environments. The ‘H’ in 347H indicates that this grade is designed for high-temperature service, with the increased carbon content providing greater creep and stress rupture properties.

These pipes are produced through a welding process that ensures a strong seam, making them suitable for various applications where seamless pipes may not be necessary or where welded pipes are more cost-effective.
