Stainless Steel 347H Screw is a highly corrosion-resistant material composed of iron, chromium, nickel, and carbon. It has higher levels of chromium than other grades of stainless steel, which resist oxidation and lead to better corrosion protection and increased strength at high temperatures. Additionally, it contains small amounts of nitrogen and titanium, enhancing internal grain structure and adding toughness. This material is ideal for components that come in contact with chemicals, such as petrochemicals or the food industry, where chemical contamination must be avoided.

Stainless Steel 347H Screws are a cost-effective, reliable fastening choice for many applications. As a type of heat-resisting steel, they have increased tensile strength and yield up to 15%, making them a good option for demanding industries such as aircraft and motor manufacturing. Their high chromium content allows them to resist corrosion in environments containing moisture, acid, and chlorine, making them an excellent option for outdoor projects or areas exposed to corrosive chemicals. However, as a substrate with a high thermal expansion coefficient and coefficient of thermal conductivity, it found the most widespread use in petrochemical furnaces, radiant tubes, furnace convection chambers, and other fittings requiring rapid heating and cooling temperatures. Furthermore,  347H Stainless Steel Screws have improved fatigue strength compared to plain steel screws.

FAQ's for Stainless Steel 347H Screw

A Stainless Steel 347H screw is a type of fastener made from stainless steel alloy that contains chromium, nickel, molybdenum and other alloys. It offers excellent resistance to high temperature environments and oxidation, which makes it ideal for applications in the petroleum and chemical industries.

Stainless Steel 347H screws feature an enhanced creep resisting property due to their high content of chromium, molybdenum, and silicon. They also have excellent grain structure and mechanical properties at elevated temperatures. Furthermore, they offer superior corrosion-resistance in extreme environments.

Stainless Steel 347H screws can be used in various applications where high temperature stability and corrosion-resistance are required such as petrochemical plants, off-shore rigs, nuclear power plants and paper mills. Additionally, they’re often used in food processing equipment that has continuous exposure to moisture or salt solutions.
