Steel Billets for Oil Field Equipment
Oil field equipment works under pressure and shock loads. Quenched and tempered alloy steels are forged and machined into collars, subs, couplings and wellhead parts.
Typical components
- Drill collars and subs
- Couplings
- Wellhead valve bodies
- Tool joints
Recommended steel grades
SAE 4140
The American-designation counterpart of EN19 and 42CrMo4. Strong, tough and easy to heat treat.
SAE 4130
A lower carbon chrome-moly steel with good weldability and strength, used in pressure and structural parts.
EN19
A widely used chrome-moly steel with good hardenability, toughness and fatigue strength in the quenched and tempered condition.
SAE 4340
A tough, high strength steel with excellent hardenability. Often chosen for heavy-duty, shock-loaded parts.
ASTM A182 F22
A creep-resistant chrome-moly steel for forged flanges, fittings and valves operating at high temperature and pressure.
Choosing the billet
State any API, NACE or residual limits at enquiry so the melt can be planned.
Check the billet size chart for sections and weight per metre, and use the weight calculator for any length.
