Stainless Steel 347H sheet, plate, and coil are high-temperature, corrosion-resistant materials made with added columbium to enhance stability. These products deliver excellent strength at elevated temperatures and resist intergranular corrosion. SS 347H sheets are outstanding for challenging operations, as it won't rust easily in corrosive environments. These plates consist of chromium, nickel, carbon, manganese, silicon, phosphorus, sulfur, columbium, and iron, as it provide long-term durability along with robust mechanical properties. Preston Pipes & Alloys is a leading manufacturer and seller of stainless steel 347H sheet, plate, and coil. It ensures that the products are exact and satisfy global quality standards, and it works well in various applications.
ASTM A240 TP347H Stainless Steel Plates possess high strength, thermal stability and chemical mix resistance. It performs impressively in environments where constant exposure to heat and corrosive agents is common. These properties make them valuable in the petrochemical, oil and gas, chemical, power plant, and energy industries. These plates are also used in the aerospace, pharmaceuticals, pulp and paper, and food processing industries. As it can handle a lot of pressure and harsh conditions, which makes them a reliable choice for crucial operations.
Stainless Steel 347H Sheets, plates, and coils are offered in different specifications to suit various requirements. The standards include ASME SA240 and ASTM A240, and the dimensions are available in ASTM, ASME, and API specifications. The widths vary between 1000 mm and 3500 mm, the thickness from 4 mm up to 100 mm, and the lengths from 2000 mm to 6000 mm. The surface finishes are sandblasted, etched, brushed, hot-rolled, and cold-rolled. We offer coils, foils, rolls, plain sheets, shim sheets and perforated sheets, and it is available in any size as per the requirement of the project. This adaptability ensures, that it can handle a wide range of installation and production methods.
Each stainless steel 347H plate, sheet, and coil undergoes rigorous quality inspections such as mechanical testing, chemical testing, and dimension testing. By using wooden cases, plastic wrapping, steel strip bundles or specially designed packages based on project requirements, secure packaging protects the material from damage during handling and transit. When we properly prioritize quality and safe delivery, the material arrives at the location in ideal condition. For reliable stainless steel 347H plates, get in touch, with us right now.
