The material is especially low temperature durable. The Super Duplex Steel Gr F55 Round Head Bolts are of high mechanical strength. Therefore the ASTM A182 Gr F55 Square Bolts are used in manifolds and flanges. The A182 Grade F55 Hex Screws have superior strength and corrosion resistance than the other grades of duplex steel made screws. We manufacture different sizes of ASTM A182 Super Duplex Steel Hex Bolts which are applicable for sour conditions. Our products are of superior quality and we pass them through all industrial standard necessary tests. The Gr F55 Heavy Hex Bolt is used to connect parts of valves, pumps and other connectors that operate under acidic conditions. There are applications such as pressure vessels, chemical industries and marine and sea water industries that use the material for durability and corrosion resistance as well. The ASTM A182 Gr F55 Hex Cap Screw is resistance to chloride corrosion so it has the advantage of easy tightening and loosening. You can contact us for further product details and pricing.
