AISI 4330V
ASTM A-29, API 7-1
GENERAL SCOPE:
4330 Mod is a low alloy steel that is used in downhole tools that require very high strength with excellent impact resistance. It is a heat treatable alloy steel that contains nominally 0.31% Carbon, with Nickel, Chromium, and Molybdenum as the primary hardening elements. This grade is widely used in downhole applications such as drilling jars.
ADDITIONAL INFORMATION
The Nickel content gives this alloy the ability to exhibit excellent impact properties at room temperature and lower. A small amount of Vanadium is typically added to this alloy for grain refinement. It is also one of the deepest hardening low alloy steels available.
This alloy is not recommended for applications that involve exposure to Hydrogen Sulfide, in accordance with NACE MR-01-75/ISO-15156.
