431 Stainless Steel

431 stainless steel is a high chromium, low nickel martensitic stainless alloy known for excellent strength, good toughness, and improved corrosion resistance compared to many other martensitic grades. AISI 431 stainless steel is ideal for applications requiring mechanical performance and durability in demanding environments.

Key Features

This grade provides high tensile and torsional strength, good polishability, and moderate corrosion resistance. 431 ss material is well suited for shafts, fasteners, pumps, and marine hardware that demand both mechanical reliability and stainless performance.

Typical Applications
  • Pump and propeller shafts
  • Valve stems, nuts and bolts
  • Marine hardware, drive shafts
  • Structural parts exposed to high stress
Forms of Supply

We offer 431 stainless steel in bars, flats, plates, rounds, and forgings. We typically supply the material in quenched and tempered (hardened) condition. We provide custom cut to size and finished formats for clients in UAE, Oman and Saudi Arabia. Silver Metal Trading LLC acts as a trusted 431 stainless steel supplier and stainless steel distributor, supporting industrial buyers with reliable, high quality materials.

Technical Specifications

Chemical Composition
  • Carbon (C): ≤ 0.20% – supports hardenability and high tensile strength.
  • Silicon (Si): ≤ 1.00% – supports de‑oxidation and strength.
  • Manganese (Mn): ≤ 1.00% – improves toughness and structural integrity.
  • Phosphorus (P): ≤ 0.04% – helps maintain ductility.
  • Sulfur (S): ≤ 0.03% – improves machinability though may reduce corrosion resistance.
  • Chromium (Cr): 15.0–17.0% – delivers corrosion resistance and hardenability.
  • Nickel (Ni): 1.25–2.50% – enhances toughness and control of martensitic structure.
  • Iron (Fe): Balance – main matrix element.
