We are a very famous supplier and Alloy steel fasteners manufactures of High Tensile Alloy Steel Fasteners, offering a complete range of alloy steel bolts, alloy steel screws, alloy steel stud bolts, alloy steel threaded rods, alloy steel nuts, and alloy steel washers. High-strength alloy steel fasteners grades (4130, 4140, 4340 and 8620 (20MnCr5) are used to manufacture these fasteners. The alloying elements in their composition such as chromium, vanadium, tungsten and molybdenum give the fasteners their exceptional strength and corrosion resistance and they are available in several Alloy steel fasteners sizes (usually in a length ranging between M12 to M72) and types.
Our alloy steel fasteners are supplied in the specialized quenched and tempered form, which is often marked by Charpy impact testing, and thus they are useful in critical low-temperature bolting. Commonly produced alloy steel bolt grades are; the industry standards of ASTM A193 B7, B7M, A320 L7, L7M, L43, and high strength metric grades such as ISO 8.8, 10.9, and 12.9. Exact production process, heat treatment, guarantees the permanence and efficiency of the end products that comprise of studs, bolts, nuts, and washers.
