Alloys

4130 is a low alloy steel that is commonly used in the oil patch, predominately in wellhead applications. It is a heat treatable alloy steel that contains nominally .30% Carbon, with Chromium and Molybdenum as the primary hardening elements.

These grades are typically used in the hot rolled, forged, or cold drawn condition without further heat treatment.

4140 is a low alloy steel that is commonly used in downhole tools. It is a heat treatable alloy steel that contains nominally .40% Carbon with Chromium and Molybdenum as the primary hardening elements

4145M is a low alloy steel that is commonly used in downhole tools, tool joints, and drill collars. It is a heat treatable alloy steel that contains nominally .45% Carbon, with Chromium and Molybdenum as the primary hardening elements.

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 .31% Carbon, with Nickel, Chromium, and Molybdenum as the primary hardening elements.

4340 is a low alloy steel that is used in downhole tools and hangers that require very high strength with excellent impact resistance. It is a heat treatable alloy steel that contains nominally .40% Carbon, with Nickel, Chromium, and Molybdenum as the primary hardening elements.
