Zusammenfassung:	An unmodified structural steel used for manufacturing the sucker rod contains C (0.26-0.35 wt.%), Mn (1.3-1.5), Si (0.8-1.05), V (0.08-0.15), Ti (0.02-0.05), Mo (0-0.04), Cr+Ni (0-0.02), Cu (0-0.25),P and S (0-0.025) and Fe (the rest). It is prepared through proportioning, rough smelting in electric furnace, refining in LF furnace, casting ingot, cogging, rolling, finish rolling, and ageing.
