Stainless Steel 347H Screw

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.
