OHNS tool steel (1.2510) is an oil hardening, “non shrinking” cold work tool steel that combines excellent wear resistance, dimensional stability, and easy machinability. Industrial metal suppliers in the UAE recommend it for a wide range of precision tooling and die applications.

Key Features

This steel offers high hardenability and retains sharp edges under heavy use. Its toughness and machinability allow cost effective production of dies, gauges, cutting tools, and precision parts with minimal distortion.

Typical Applications
  • Blanking, forming and trim dies for cold working sheets
  • Slitting cutters, shear blades and machine knives
  • Thread rolling dies, broaches and precision tooling
  • Plastic mould inserts, gauges and measurement devices
  • Low-volume or general purpose tooling where cost and performance must be balanced
Forms of Supply

Supplied in annealed condition (~229 HB) as peeled or turn machined rounds, flats, squares, and blocks, this material is offered by best metal steel trading llc, one of the leading tool and die steel distributors. It is available in standard sizes or cut to length, with delivery across the UAE and Gulf region.

OHNS tool steel (1.2510) is an oil hardening cold work steel designed to provide excellent wear resistance and dimensional stability. Its non shrinking property ensures minimal distortion during heat treatment, making it ideal for producing precision dies, cutters, and gauges. Industrial metal suppliers in the UAE and Gulf region recommend it for applications where accuracy and reliability are critical.

 

This grade combines high toughness with good machinability, enabling manufacturers to produce long lasting tooling components efficiently. As trusted O1 HNS tool steel suppliers, we provide stock to customers in Oman, Saudi Arabia, and across the Middle East. It performs consistently under repeated use, delivering sharp edges and maintaining shape even in demanding cold work applications.

Applications of OHNS Tool Steel
  • Blanking, forming, and trim dies for sheet metal
  • Slitting cutters, shear blades, and machine knives
  • Thread rolling dies, broaches, and precision tooling
  • Plastic mould inserts, gauges, and measurement devices
  • Low-volume or general purpose tooling requiring durability and cost efficiency

Technical Specifications

Chemical Composition
  • Carbon (C): 0.90-1.05% – High carbon content contributes to strong carbide network and excellent wear resistance.
  • Manganese (Mn): 1.00-1.20% – Enhances strength and hardenability.
  • Silicon (Si): 0.15-0.35% – Supports strength and machinability.
  • Chromium (Cr): 0.50-0.70% – Provides improved hardenability and resistance to wear.
  • Tungsten (W): 0.50-0.70% – Contributes to hardness retention and carbide formation.
  • Vanadium (V): 0.05-0.15% – Refines grain structure and improves toughness.
  • Phosphorus (P): ≤ 0.03% – Limits brittleness.
  • Sulfur (S): ≤ 0.03% – Maintains good machinability.
Treatment
  • Annealing: Heat to approx. 750-780 °C, hold to equalise temperature, then furnace-cool slowly to circa 600 °C to achieve ≤ 229 HB for machining readiness.
  • Hardening: Pre-heat to ~650 °C, then austenitise at ~780-820 °C for full transformation, followed by oil quench (or suitable medium) depending on section size.
  • Tempering: Immediately temper after quench; typical tempering temperature 150-250 °C to achieve hardness between ~57-62 HRC depending on section size.
  • Finishing Machining & Polishing: Excellent dimensional stability during heat treatment allows precision tooling with minimal distortion and good surface finish.
