AISI 4140 is a versatile chromium molybdenum alloy steel known for its high strength, toughness, and excellent fatigue resistance. Often referred to as SAE 4140 steel, it offers superior performance as provided by the leading Alloy and Carbon Steel Suppliers. Trusted 4140 steel suppliers like Silver Metal Trading recommend this grade for demanding engineering applications.

Key Features

This AISI 4140 alloy steel offers excellent toughness, fatigue resistance, and wear properties. As prominent Alloy and Carbon Steel manufacturers, we ensure it is suitable for hardening and tempering, providing a balance of strength and ductility ideal for shafts and axles in the UAE, Oman, and Saudi Arabia.

Typical Applications
  • Crankshafts, gears, and pump shafts
  • Tool holders and stem assemblies
  • Conveyor pins and collets
  • Connection rods and high stress parts
Forms of Supply

Available as round bars, sheets, and ground bars. As expert Alloy and Carbon Steel distributors, we serve major industrial hubs, delivering material aisi 4140 to the UAE, Oman, and Saudi Arabia, with precision ground bars available for tight tolerances.

AISI 4140 is a chromium molybdenum alloy steel characterized by high strength and toughness. Commonly specified as SAE 4140 steel, this grade is significantly more versatile than standard carbon steel. As expert Alloy and Carbon Steel traders, we ensure it contains chromium, which provides hardness penetration, and molybdenum, which ensures uniform hardness and high strength. Consequently, the material AISI 4140 responds exceptionally well to heat treatment. Therefore, it maintains its fatigue strength even at elevated temperatures, making it the standard choice for engineering sectors in the UAE, Oman, and Saudi Arabia.

Key Advantages
  • Excellent hardness and wear resistance after heat treatment
  • High fatigue strength and impact resistance
  • Good ductility and machinability in annealed condition
  • Available in quenched and tempered or annealed forms
  • Uniform hardness and strength throughout the bar

We supply AISI 4140 steel in various forms, including bars and plates, acting as dedicated 4140 steel suppliers and leading Alloy and Carbon Steel manufacturers. As experienced metal traders, we ensure quality by collaborating with top tier steel manufacturers in UAE. This allows us to provide premium ferrous material that meets international standards. Our logistics network as Alloy and Carbon Steel distributors ensures rapid delivery to the UAE, Oman, and Saudi Arabia. Whether you need cut to size pieces or bulk orders, our ready stock guarantees minimal downtime for your projects.
