At Hazlewood Fasteners in Canberra, we engineer endurance into every component. Our stainless steel 347H washers are built for extreme environments where heat, pressure, and corrosion converge. Designed with enhanced carbon content for superior creep strength, these washers maintain structural stability and oxidation resistance even under prolonged thermal exposure. Precision-crafted to protect joints, distribute loads, and reinforce connections, Hazlewood Fasteners’ 347H washers deliver reliability that outlasts the elements. When performance at high temperatures is critical, these washers ensure every assembly stays tight, resilient, and true to the strength of Hazlewood engineering excellence.
Stainless steel 347H washers are forged from a niobium-stabilized, high-carbon austenitic stainless steel alloy. The composition—rich in chromium and nickel—offers excellent resistance to intergranular corrosion, oxidation, and thermal fatigue. The elevated carbon content enhances creep and tensile strength during extended service at elevated temperatures. These washers maintain their mechanical integrity under severe thermal cycling and mechanical stress, combining toughness with dimensional precision. With outstanding high-temperature performance and corrosion resistance, 347H washers ensure lasting protection and load balance for critical industrial and structural assemblies.

Stainless steel 347H washers excel in high-temperature and corrosive environments where ordinary materials fail. They are widely used in petrochemical plants, refineries, power generation systems, and heat exchangers, where they safeguard joints under constant thermal and mechanical strain. In furnace components, boiler assemblies, and pressure vessels, they maintain stability and strength at temperatures up to 870°C. Their resistance to oxidation and creep makes them ideal for demanding aerospace, marine, and structural applications. Hazlewood Fasteners’ 347H washers deliver performance you can trust—ensuring every connection remains secure, balanced, and built to endure the heat of industry.
