iso grade 12.9 threaded rod and bar
ISO grade 12.9 steel bar is used to produce iso grade 12.9 Threaded Rods and iso grade 12.9 anchor bolt. We produce iso grade 12.9 hot rolled and qt steel round and and iso grade 12.9 cold drawn and qt steel round bar. ISO grade 12.9 is one kind of alloy quenched and tempered grade in ISO898 standard.ISO grade 12.9 threaded rod is usually metric threaded rods. sae iso grade 12.9 steel rod we produce is to produce fully threaded stud bolts used for High Strength Steel Bolts such as marine anchor bolt, mine steel anchor bolt, wind turbine anchor bolt.
ISO grade 12.9 threaded rod is famous for its high demand because of its high strength, excellent heat resistance and resistance to corrosion.
