Product Description

BS 590M17 (historically associated with the EN351 family or variant specifications under BS 970) is a low-alloy, chromium-manganese case-hardening (carburizing) steel. It is widely supplied as round bars, rods, and blocks for engineering applications that require a highly wear-resistant surface coupled with a tough, ductile core.

Here is a technical overview of its specifications, international equivalents, chemical composition, and typical mechanical profiles.

Technical Specifications & Cross-References

When cross-referencing global standards to source equivalent round bars, the closest matches include:

Standard Designation / Grade
British Standard (BS 970) 590M17 / 527M17
European (EN / DIN / WNr) 16MnCr5 / 1.7131
AISI / SAE (USA) 5115 / 5117
AFNOR (France) 16MC5
GOST (Russia) 18KhG (18) / 15HG
JIS (Japan) SCr415

Chemical Composition

The performance of 590M17 relies on a controlled balance of manganese and chromium to optimize hardenability during case hardening.

  • Carbon (C): 0.14% 0.19% (low carbon allows the core to remain tough after quenching)

  • Manganese (Mn): 1.00% 1.30%

  • Chromium (Cr): 0.80% 1.10%

  • Silicon (Si): max. 0.40%

  • Phosphorus (P): max. 0.035%

  • Sulfur (S): max. 0.035% (enhanced machinability variants may feature controlled higher sulfur)

Key Mechanical Properties & Characteristics

Because it is a case-hardening grade, its final mechanical properties depend highly on the heat treatment (carburizing, quenching, and tempering).

  • Hardenability: It offers low-to-medium core hardenability. It is optimized for maintaining structural core toughness in small-to-medium section sizes (typically up to 20 mm to 50 mm ruling sections).

  • Core Tensile Strength: Typically around 7001000 MPa post-heat treatment, depending on diameter.

  • Supply Condition: Commonly supplied in the As-Rolled,Normalized, or Soft Annealed (max. 207 HBW) state to maximize precision and tool life during initial machining.

Core Applications

Due to its excellent forgeability, response to carburizing, and balanced machinability (approx. 80% of mild steel), 590M17 round bars are heavily utilized in power transmission and heavy-duty clamping hardware:

  • Gears and Pinions: Severe surface wear resistance with high shock resistance.

  • Shafts and Camshafts: Excellent performance under cyclic fatigue.

  • Heavy Clamping & Fasteners: Specialized joint components, gudgeon pins, and heavy-duty bolts requiring localized wear resistance.



Superior Mechanical Properties

These BS 590M17 round bars exhibit excellent strength, with a yield strength near 560 MPa and an ultimate tensile strength around 800 MPa. Their good machinability makes them suitable for components requiring intricate fabrication, like shafts and engineering parts.


Flexible Sizing and Finishing Options

With custom lengths (typically 3 to 6 meters) and a diameter range from 10mm to 300mm, these bars are manufactured using hot rolled, forged, or peeled techniques. The surface condition can be peeled or polished, providing bright or black finishes as per project requirements.


Certified Quality and Readily Available

Every bar is supplied with a Mill Test Certificate according to EN10204:3.1/3.2. Stock is readily available, and packaging can be customized in bundles or as specified, ensuring prompt delivery for projects.
