About Stainless Steel 347/ 347h Pipe Fittings?

Stainless Steel 347/347H Pipe Fittings are essential components used in the installation and connection of pipelines in various industries. These fittings are specifically designed to accommodate the characteristics of stainless steel alloys 347 and 347H, which are known for their corrosion resistance and high-temperature performance.

Stainless Steel 347: This austenitic stainless steel alloy contains chromium, nickel, and columbium (niobium). The addition of niobium enhances the alloy's resistance to intergranular corrosion, particularly after exposure to sensitizing temperatures.

Stainless Steel 347H: Similar to 347, but with a higher carbon content, 347H offers improved high-temperature strength. The "H" denotes the higher carbon content.

Stainless Steel 347/347H Pipe Fittings are specialized components tailored for industries requiring reliable and durable connections in environments with corrosive elements and high operating temperatures.
