Product Description

SN 14 220 is a prominent Czech standard (SN) structural alloy steel primarily utilized for case-hardening (carburizing). It is highly valued for engineering components that demand a exceptionally hard, wear-resistant surface profile combined with a tough, impact-resistant core.

Global Cross-Reference & Equivalents

When sourcing SN 14 220 round bars or rods internationally, you will find it most frequently cross-referenced under the European standard 16MnCr5:

Standard System Designators / Equivalents
SN (Czech Republic) 14 220
W.Nr. / EN (Germany/Europe) 1.7131 / 16MnCr5
GOST (Russia/CIS) 18KhG (18) / 15KhF
AISI/SAE (USA) 5115 / 5117 (Closest fit)

Chemical Composition (Typical wt.%)

The alloy chemistry relies heavily on a precise manganese-chromium balance to boost hardenability and core strength during case hardening.

  • Carbon (C): 0.14% -0.19%

  • Manganese (Mn): 1.10% -1.40%

  • Chromium (Cr): 0.80% - 1.10%

  • Silicon (Si): 0.17% - 0.37%

  • Phosphorus (P):  0.035%

  • Sulfur (S): 0.035%

Technical Specifications & Supply Conditions

SN 14 220 round bars and rods are typically supplied in the following profiles:

1. Delivery States

  • Annealed (+A): Soft-annealed for optimum machinability (typically 207 HBW).

  • Normalized (+N): Grain-refined structure to prepare for subsequent forging or machining.

  • Treated for Machinability (+TH / +FP): Optimized microstructure for high-speed cutting.

2. Standard Mechanical Properties (Core Properties post Heat-Treatment)

  • Tensile Strength (R): 780 -1100 MPa (depending on cross-section diameter)

  • Yield Strength (R: 440 MPa

  • Elongation (A5):  9% -10%

  • Impact Energy (KV):  32 J

Typical Applications

Because it responds exceptionally well to gas, powder, or salt-bath carburizing (at process temperatures around 900C 930C), this material is standard for high-fatigue, high-load machinery components up to roughly 35 mm in critical cross-section:

  • Power Transmission: Small-to-medium spur gears, bevel gears, pinion shafts, and spline shafts.

  • Automotive & Engine Components: Camshafts, piston pins, valve lifters, and universal joint journals.

  • Tooling & Workholding: Clamping jaws, heavy-duty guide bushes, jaw clutches, and positioning pins.

FAQ's of CSN 14220 Alloy Steel Bar 14220 Round Bars 14220 Rods:


Q: How are CSN 14220 Alloy Steel Bars processed to ensure strength and durability?

A: CSN 14220 Alloy Steel Bars are processed primarily through hot rolling or forging. Additional treatments such as annealing and peeling are applied to refine grain structure, reduce internal stresses, and enhance surface quality. This combination ensures the bars possess optimal strength and long-lasting durability for industrial use.

Q: What applications are most suitable for 14220 round bars and rods?

A: These bars are highly suited for construction, engineering, and manufacturing sectors. Specifically, they are used in the fabrication of shafts, gears, and various machine parts, offering excellent mechanical properties required for critical load-bearing and dynamic applications.

Q: When should I opt for a specific surface finish like polished or black for my steel bars?

A: The choice of surface finish depends on the intended application's requirements. Polished bars offer superior aesthetics and corrosion resistance, making them ideal for visible or precision engineering work. Black finishes are typically chosen for standard mechanical or structural applications where appearance is less critical.

Q: Where can I source CSN 14220 Alloy Steel Bars and in what sizes?

A: These bars are available through dealers, exporters, fabricators, manufacturers, producers, retailers, suppliers, and traders across India. Sizes range from diameters of 10 mm to 300 mm and lengths from 3000 mm to 6000 mm, provided with standard export packing and customized as per client needs.

Q: What is the process for customizing bars as per customer requirements?

A: Customers can specify requirements regarding size, surface treatment, finish, tolerance, and delivery conditions. The manufacturer adapts processing techniques (forging, rolling, annealing, etc.) and quality checks to deliver bars that precisely meet those specifications.

Q: What benefits does the CSN 14220 standard offer over regular alloy steel bars?

A: The CSN 14220 standard ensures the alloy steel bars meet stringent chemical composition and mechanical property criteria, guaranteeing consistent quality. This results in reliable performance, particularly for demanding applications in engineering and machinery sectors.
