AISI 4145 is a high grade chromium molybdenum alloy steel tailored for the oil and gas industry. Known for its high strength and hardenability, it surpasses standard 4140 grades in heavy duty applications. As specialized 4145 steel suppliers and leading Alloy and Carbon Steel distributors in the GCC, we ensure premium quality for downhole tools.

Key Features

This 4145 material offers improved hardenability due to higher carbon content. It is ideal for larger diameters, ensuring consistent hardness and strength throughout the bar. Its durability makes it the preferred choice for steel manufacturers in UAE and prominent Alloy and Carbon Steel manufacturers for drill collar applications.

Typical Applications
  • Drill collars and downhole drilling tools
  • Gears and shafts for hydraulic presses
  • Rolls for paper mills and pump shafts
  • Stabilizers and connection rods
Forms of Supply

Supplied as round bars, often precision ground for tight tolerances. As expert Alloy and Carbon Steel traders, we serve major hubs, delivering AISI 4145 alloy steel across the GCC region, supporting the drilling sector with ready stock.

4145 alloy steel is a premium chromium molybdenum grade designed specifically for high stress environments. Commonly specified as AISI 4145, this material contains higher carbon levels than the 4140 grade. As dedicated Alloy and Carbon Steel traders in the GCC, we ensure this grade offers superior hardenability and tensile strength. Therefore, it is the standard choice for manufacturing heavy duty drill collars and downhole tools in the oil and gas sector. The 4145 material maintains excellent mechanical properties even in larger cross sections, ensuring reliability where other alloys might fail under extreme pressure.

Key Advantages
  • Higher carbon content for increased strength and hardness
  • Excellent hardenability in larger diameters
  • Superior resistance to wear and abrasion
  • Ideal for high torque drilling components
  • Consistent mechanical properties after heat treatment

We specialize in supplying 4145 steel in various forms, acting as reliable 4145 steel suppliers and Alloy and Carbon Steel Suppliers for critical industries. As experienced traders of ferrous metals, we collaborate with leading steel manufacturers in UAE to provide certified stock. Our robust supply chain effectively supports steel manufacturers in Oman and Saudi Arabia who require urgent material for rig maintenance. We deliver directly to industrial zones throughout the GCC. Whether you need single bars or bulk shipments, Silver Metal Trading ensures your drilling operations continue without delay as the region’s trusted Alloy and Carbon Steel distributors.
