AISI 4130 is a low-alloy chromium molybdenum steel with strong weldability, good toughness and high strength. It is widely used for critical engineering and oil & gas applications where a reliable balance of performance and fabrication ease is needed.

Key Features

This aisi 4130 alloy steel provides superior weldability and machinability compared to many higher carbon steels. Its chromium and molybdenum content improves hardenability, wear resistance, and high temperature strength. With proper heat treatment, it delivers excellent toughness and strength for industrial and oil and gas operations. Supplied by trusted industrial metal suppliers and non ferrous metal traders in UAE, it meets demanding project requirements.

Typical Applications
  • Oil & gas drilling and production equipment (valve bodies, flanges, tubing)
  • Structural and mechanical components in heavy machinery
  • Aerospace and motorsport tubing or bar stock subject to high stress
  • Automotive chassis, roll cages or high performance parts requiring strength and weldability
Forms of Supply

Available as bars, plates, and forgings in normalized, quenched, and tempered conditions. Custom cut to size and machined lengths are offered for delivery across the UAE and Gulf region by leading metal trading companies in UAE.

Technical Specifications

Chemical Composition
  • Carbon (C): 0.28 – 0.33% – balanced for strength and weldability.
  • Chromium (Cr): 0.80 – 1.10% – enhances hardenability and wear resistance.
  • Manganese (Mn): 0.40 – 0.60% – supports strength and toughness.
  • Molybdenum (Mo): 0.15 – 0.25% – boosts elevated temperature and creep performance.
  • Silicon (Si): 0.15 – 0.35% – deoxidiser and strength contributor.
  • Phosphorus (P): ≤ 0.035% – maintains toughness and reduces brittleness.
  • Sulfur (S): ≤ 0.040% – kept low to ensure weldability.
  • Iron (Fe): Balance – principal matrix element.
Mechanical Properties
  • Density: ~7.85 g/cm³ (0.284 lb/in³)
  • Ultimate Tensile Strength (UTS): ~560 MPa
  • Yield Strength: ~460 MPa
  • Modulus of Elasticity: ~190 – 210 GPa
  • Brinell Hardness: ~197 HB in normalized condition
