An SS 310 Threaded Rod is a long, continuously threaded bar used as a high-strength, structural fastener or anchor in high-temperature applications. It functions similarly to a stud bolt but often comes in stock lengths that can be cut to custom size on-site. The rod is manufactured from a high-chromium and high-nickel austenitic stainless steel (UNS S31000), a composition specifically designed for extreme thermal service. This material offers outstanding resistance to oxidation and scaling in continuous service up to 2000°F (1093°C). The high alloy content ensures that the rod maintains significant creep strength and dimensional stability under prolonged thermal loads and cycling. This makes SS 310 Threaded Rods indispensable for anchoring refractory linings, suspending piping, and securing large structural members within industrial furnaces, kilns, and high-temperature reactors. Zeron Fasteners manufactures and supplies durable SS 310 Threaded Rods in various lengths and thread specifications for critical, high-heat industrial assembly.
