At Astec Tubes we manufacture and supply the uppermost quality of Alloy Steel, Inconel Steel, and Stainless Steel Products, etc. Our company is well-known for its quick and ready services. Our SS 347/347H Pipe Fittings is one of the most demanded products around the region. This product is widely used in different applications. It is acquired as per necessity as it has several types at all competitive prices. This particular stainless steel is inclusive of durable functioning and excellent Corrosion resistance. Also, it has the malleability, heat resistance, high strength, and conductivity. Grade 7347 and 347H is mostly utilized in the Pressure vessels and tanks, Industrial boilers, Pulp, and paper processing equipment. Also, in the Heat exchanger tubes, High-temperature chemical processing equipment, Oil and petrochemical refineries they are widely used. The pipe fittings are the best used in the industries which are having many characteristics.

Grade 347 is the austenitic stainless steel with the composition of 0.08% carbon, 2% manganese, 1% silicon, 0,045% phosphorus, 0.03% sulfur, 17 % chromium, 0.1% nitrogen, and 9% to 12% nickel. Similarly, Grade 347H has composed of 0.04 to 0.10 % carbon and rest components are in the same proportions. It has the melting point to 1457°C or 2650° F and elongation at 35%. This grade works fluently in cold working. SS UNS S34700 / S34709 Pipe Fittings comes in a variety of forms like seamless, welded and fabricated. Grade 347 and 347 H has variant types based on different shapes. Like 347H 45 Degree Elbow, Eccentric Reducer, Concentric Reducer, Lateral Tee, Equal Tee and Cross, and bends. Each type has its function to fulfill like SS 347h equal is used for making a connection with three pipes. Likewise, the lateral tee is used for joining two pipelines. 45-degree elbows are used for making a joint on the curvy surface. Grade 347 and 347H is governed by the ASME or ANSI, ASME, and MSS-SP-43.
