DC Engineering is the manufacturer, supplier, and stockist of metal and steel products Jf Bolts provides the best quality metal products. We at JF Bolts make sure that every product is strictly tested and certified by our professionals. JF Bolts is the number one supplier of Inconel 800/800H/800HT bolts. These bolts are highly demanded in all types of industries. Inconel 800/800H/800HT bolts are highly durable and robust. These Inconel 800 U-Bolt are made of an excellent combination of nickel-chromium-iron. Nickel and chromium have excellent properties that make the grade extra solid and pliable. Inconel 800H Square Bolt also protects an alloy from all types of chemical reactions. It also improves the durability and strength of the stage. Hence they are used in various chemical industries.

Inconel 800 has excellent malleability, and it provides excellent resistance from oxidation. Inconel 800H has superior welding and forming properties. Rupture and creep strength (above 1100°F/ 600°C). Similarly, Inconel 800HT also has creep and rupture strength of 1290°F (700°C). Other than that, the tensile and yield strength of Inconel 800Ht bolts is also high. These bolts are incredibly sturdy and robust, and they have excellent characteristics of holding material or two or more pieces together. Hence they are applicable in various industries.
