ALLOY ROUND STEEL – ENGINEERING WONDERS IN STEEL FABRICATION

In today’s steel market, alloy steels come in a vast array of products, prices, and qualities depending on their specific compositions. One of the most sought-after products is alloy round steel. Let’s explore this specialized steel with Chau Duong.

1. What is Alloy Round Steel?

Alloy round steel primarily consists of carbon and iron, with added alloying elements such as chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), vanadium (V), cobalt (Co), titanium (Ti), and copper (Cu), enhancing properties like elasticity, strength, malleability, heat resistance, magnetic qualities, thermal expansion, and corrosion resistance.

2. Alloy Round Steel Grades

• 40CrNiMoA (GB): SNCM439 (JIS), 4349 (ASTM), 36CrNiMo4 / 1.6511 (EN), 816M40 (EN)

• 20Cr2Ni4 (GB): 3316 (ASTM)

• 17CrNiMo6-4 (EN): 1.6566 (EN), 4720 (ASTM), SNCM420 (JIS), 18CrNiMnMoA (GB)

• 20CrNiMoA (GB): SNCM220 (JIS), 8620 (ASTM), 20NiCrMo2-2 / 1.6523 (DIN), 20CrNiMo2 (DIN)

• 34CrNiMo6 (GB): 1.6582 (DIN)

• 30CrNiMo8 (GB): 1.6580 (DIN)

• 18 CrNiMo7-6 (EN): 17CrNiMo6 (DIN), 17Cr2Ni2Mo (GB), 1.6587 (EN)

3. Dimensions of Alloy Round Steel

• Hot-Rolled Round Steel: Φ14 - Φ320mm x L4500 - L11800mm

• Cold-Drawn Round Steel: Φ2 - Φ100mm x L3000 - L6000mm

• Forged Round Steel: Φ90 - Φ1500mm with length customized per client specifications

The dimensions of alloy round steel can be tailored to the specific requirements of the customer.

4. Properties of Alloy Round Steel

• Exceptional strength, particularly after quenching and tempering, making it far more durable than carbon steel.

• High mechanical properties are retained, even at temperatures exceeding 200°C, with additional elements.

• Other features such as magnetic properties, thermal expansion, and corrosion resistance have been rigorously tested on alloy steels.

5. Applications of Alloy Round Steel

Alloy round steel finds wide applications across various industries, from construction, mechanical fabrication, automotive components, to marine equipment, thanks to its outstanding properties. Industries also employ this steel type in manufacturing engine shafts, light- to medium-load shafts, gears, and machinery parts such as rollers, bolts, and crank arms.
