At Sunbelt Steel, we carry a wide variety of highly specialized grades of alloy and carbon steel. Our diverse steel stock is perfect for both down-hole and top-side drilling products such as drilling subs, drill collars, valves, hydraulic fracturing components, shock tools, mud motors, stabilizers and more. If you need premium alloy steel, we have you covered. Discover our 4140 steel stock below.
The versatile 4140 is a chromium-molybdenum grade steel used in a multitude of industries and applications due to its good ductility and shock resistance. Greater carbon content gives it higher strength and better hardenability than 4130, although it is more difficult to weld.
Typical Applications Include:
- Tool joints
- Drill string components
- Mud motor components
4145H steel grade is the dependable standard for a wide array of applications — made even more so with Sunbelt’s Sure Bar promise.
