INGERSOLL-RAND OILFIELD PRODUCTS ESR 4330 MOD is a modified 4330 alloy steel produced by electric-furnace melting, vacuum degassing and electroslag remelting with the use of small-heat-size technology. Electroslag refining improves cleanliness and lowers the sulfur content to provide improved isotropy, ductility and toughness. This steel is ideally suited for many critical applications in oil-field and power-generating equipment as well as for machinery in the metalworking, chemical-process and construction fields. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-388. Producer or source: Ingersoll-Rand Oilfield Products Company.
