Request For Our Latest Prices On SS 347H Washers in Bangkok, Thailand!
Pengkumta Fasteners, based in Bangkok, Thailand, makes and supplies top-grade Stainless Steel 347H Washers designed for high-temperature uses. These washers are produced from a stabilized austenitic stainless steel alloy with a high carbon content to improve creep strength and thermal durability. Stainless Steel 347H Washers are used in fields where resistance to intergranular corrosion and high-temperature strength are crucial. Our manufacturing processes ensure precision, consistency, and compliance with international standards.
Stainless Steel 347H contains 17–20% chromium, 9–13% nickel, and columbium (niobium) for stabilization, with a carbon content of 0.04–0.10%. This mix prevents carbide precipitation and provides resistance to intergranular corrosion. It offers tensile strength up to 750 MPa, yield strength around 400 MPa, and excellent creep resistance.

Stainless steel 347H washers are a must for applications that require reliable performance in high corrosion temperature conditions. It is widely used in chemical plants to protect equipment exposed to acidic environments and high temperatures. In aerospace applications, 347H washers ensure safe bonding of materials under extreme heat and stress. Additionally, stainless steel 347H washers which find an important application in oil and gas refineries due to their resistance to sulfide stress cracking and nuclear reactors due to their resistance to radiation and high temperatures offer durable and reliable solutions in challenging industrial environments.
Stainless Steel 347H Washers are essential in high-temperature, high-pressure systems such as nuclear reactors, steam lines, heat exchangers, and chemical processing facilities. They maintain performance, preventing loosening or leakage in bolted assemblies exposed to thermal expansion and vibration. Their stabilized austenitic structure resists carbide precipitation during welding, making them crucial for welded assemblies in pressure vessels and pipelines.
