4330 Forged Bar Characteristics
4330 is a low alloy steel that is used in downhole tools that require very high strength with excellent impact resistance. This alloy steel is heat treatable containing .31 percent carbon with nickel, chromium and molybdenum as the primary hardening elements.
The nickel content allows 4330 alloy steel bars to have exceptional impact properties at room temperature and lower. A small amount of vanadium is typically added to this alloy for grain refinement. It is one of the deepest hardening low alloy steels available.

FAQs
4330 is built for applications demanding very high strength paired with excellent impact resistance, most commonly downhole tools and other oilfield equipment components that face severe service conditions. Its nickel content gives the alloy strong impact properties even at low temperatures, while a small vanadium addition refines the grain structure for better toughness. 4330 is among the deepest hardening low alloy steels Cromdane Steel carries, making it a strong choice when section size would otherwise limit how thoroughly a part can be hardened.

No. Both are nickel-chromium-molybdenum alloy steels, but they’re formulated for different jobs. 4330 runs around 0.31% carbon and includes a small vanadium addition for grain refinement, giving it exceptional impact resistance and some of the deepest hardenability in the low alloy steel family, which is why it’s the standard choice for downhole tools. 4340 carries a higher carbon content and no vanadium, and is typically supplied hardened and tempered in the 135-160 ksi tensile range for general highly stressed parts rather than impact-critical oilfield service.
