Polished rods play a vital role in the oil and gas industry, serving as a connector between sucker rods and the pump unit. Manufactured according to API 11B specifications, these rods are typically made from AISI-recommended series steels, including carbon steel (AISI 1035-1050), stainless steel (AISI 304/316 or 431), and alloy steel (AISI 4120-4140, 4315-4340, 4615-4625, 8620-8630). These rods possess excellent mechanical properties, ensuring their strength and ability to withstand high loads and pressures during oil and gas operations. For detailed information on composition, limits, and finishing requirements, it is crucial to consult the manufacturer's material specifications.
