Stainless Steel 347H Valves boost a unique chemical composition that sets them apart. These valves are composed of 20-24% chromium, 17-20% nickel, up to 2% molybdenum, and a maximum of 0.045-0.08% titanium or columbium. While nickel and chromium create exceptional corrosion resistance, molybdenum is responsible for the superior strength at high temperatures - making it suited to applications with extreme temperature fluctuations like power generation plants, aircraft exhaust systems, and more. With its wide range of properties, SS 347H Valves offer an ideal solution for many industrial projects.

Stainless steel valves 347H are incredibly durable and practical. They are made of chromium, nickel, columbium, and tantalum material, meaning they can most often be utilized to tolerate temperatures up to 870° C. The high-alloy content also ensures durability against corrosion at elevated temperatures. These properties make them ideal in harsh environments like the automotive industry. Due to their comprehensive range of alloys, these valves can also be used for general industrial services involving harsh chemicals, such as sulfuric acid manufacturing plants, pickling services, pharmaceuticals, and petrochemicals. In short, 347H stainless steel valves offer a viable solution for many industries needing excellent heat resistance mixed with robust construction and reliable seals.

FAQ's for Stainless Steel 347H Valves

Stainless Steel 347H Valves offer excellent corrosion resistance, good mechanical properties, and excellent creep resistance at high temperatures.
