TYPICAL APPLICATIONS

When first becoming more prevalent back in the early 1900s EN24 was classified as a wrought steel for automobiles and aircraft and as such was used to produce numerous parts and components for these industries. It is most popular as EN24T and with good high tensile properties in T condition, it is used widely in the manufacturing sector. Some examples of applications include:-

• Power transmission gears and other gears requiring maximum hardness.
• Cranks, axles, propellors, and gearbox shafts require good high tensile properties.
• Connecting rods, special cranks, and other parts required to be stiff and yet retain a high degree of toughness.
• Bolts, screwed parts, stub axles, and swivel arms required very tough.
• Plastics and rubber molding industry parts for molds, hob retaining rings and stop pins.
• Structural components with good high tensile needs.

EN24 Round Bars: Properties, Applications, and Sourcing in the UAE 

A mainstay of high strength engineering components worldwide, EN24 Round Bars are even more crucial in the harsh industrial environment of the United Arab Emirates. The preferred material for demanding, heavy-duty applications is EN24 (also known as 817M40 steel), which is renowned for its remarkable tensile strength, hardness, and remarkable wear resistance. Everything engineers, procurement managers, and fabricators in the United Arab Emirates require to know about EN24 Round Bars is included in this comprehensive reference, which will help you make well-informed decisions for your projects. 

What is EN24 Steel? Understanding the Grade 817M40 

British Standard BS 970 defines EN24 as a high-quality alloy structural steel grade. 817M40 is its corresponding material specification. "EN" stands for "Engineering Steel," and "24" is a unique identification number for this composition of nickel, chromium, and molybdenum alloy. 

These components work together to give EN24 its well-known traits: 

• Nickel (Ni): Increases strength and resilience, especially in cold climates. 

• Chromium (Cr): Increases wear resistance, corrosion resistance, and hardenability. 

• Molybdenum (Mo): Strengthens the steel even more and lowers the chance of brittleness. 

In particular, the "T" in EN24T indicates that the material is heat-treated, or hardened and tempered, and prepared for final usage and machining. 

Key Mechanical Properties and Specifications of EN24 Round Bars 

Knowing the specifications is essential when choosing materials for high-stress settings, such as those found in the construction or oil and gas industries in the United Arab Emirates.

EN24 Chemical Composition 

Why Choose EN24T Steel? Top 5 Advantages for UAE Industries 

1. Superior Strength-to-Weight Ratio: Superior Strength-to-Weight Ratio: EN24T makes it possible to build parts that are more robust and long-lasting without being overly bulky, which is essential for aerospace and mobile machinery applications. 
2. Excellent Fatigue Resistance: Outstanding Fatigue Resistance: It is ideal for shafts, gears, and other dynamic components frequently found in the manufacturing and energy sectors since it can tolerate several loading and unloading cycles. 
3. Good Machinability in Treated State: Good Machinability in Treated State: EN24T is pre-hardened, which saves time and money by allowing it to be machined to exact tolerances without the fabricator having to do additional heat treatment. This is in contrast to many high-strength steels. 
4. Responsive to Further Heat Treatment: EN24 can be flame or induction hardened to produce a robust, wear-resistant shell while maintaining a tough core for applications needing even greater surface hardness. 
5. Reliability in Challenging Environments: Equipment operating in the abrasive, sandy Gulf climate benefits greatly from its alloy composition, which provides superior resistance to atmospheric corrosion and wear compared to carbon steels. 

Primary Applications of EN24 Round Bars in the UAE 

Because of its strong qualities, EN24 is essential to the main industries in the UAE: 

• Oil & Gas Industry: Drill collars, pump shafts, valve parts, and heavy-duty fasteners that must endure high pressures and corrosive conditions are all part of the oil and gas industry. 

• Power Generation & Desalination Plants: Critical infrastructure components such as turbine shafts, generator rotors, and high-strength bolts are found in power generation and desalination plants. 

• Construction and Heavy Lifting: Parts for cranes, excavators, bulldozers, and piling equipment employed on large-scale projects in Dubai and Abu Dhabi are related to construction and heavy lifting. 

• Marine and Offshore: Offshore and marine: Parts of deck machinery, rudder stocks, and propeller shafts that are subjected to salty environments. 

• Automotive and Aerospace: Axles, connecting rods, landing gear elements, and hydraulic cylinders are examples of high-stress components. 

• General Engineering: Bolts, studs, pinions, and gears for industrial equipment. 

EN24 vs. Other Alloy Steels: A Quick Comparison for Engineers 

• EN24 vs. EN8: Steel with a medium carbon content is EN8. Because of its alloy content, EN24 is much stronger and more durable. While EN24 is for high-stress applications, EN8 is frequently utilized for non-critical parts. 
• EN24 vs. EN19: Both are steels made of chromium and molybdenum. Because EN24 contains nickel, it is more resilient to impact and more durable than EN19, making it appropriate for harsher environments. 
• EN24 vs. AISI 4340: They are exact counterparts. The American standard, AISI 4340 (UNS G43400), is nearly the same as EN24/817M40 in terms of composition and characteristics. For foreign projects in the United Arab Emirates, this is a crucial point. 

Sourcing EN24 Round Bars in the UAE: A Buyer's Checklist 

When procuring EN24 in the UAE, consider these factors to ensure quality and reliability: 

1. Material Certification: A Mill Test Certificate (MTC) or Certificate of Conformity (COC) that verifies the mechanical characteristics and chemical composition in accordance with BS 970 or BS EN 10083-3 standards should always be insisted upon. 

1. Supplier Expertise: Select a supplier or stockist who has a track record of providing the industry with premium alloy steels. They ought to offer technical assistance. 

1. Availability and Size Range: To save waste and lead time, a reputable supplier will keep a large variety of diameters and lengths in stock. 

1. Competitive Pricing: Although quality is crucial, prices should be reasonable. Prices that look too good to be true should be avoided since they could be a sign of subpar or uncertified materials. 

FAQ: EN24 Round Bars  

What is the price of EN24 round bars per kg in the UAE?  

The diameter, quantity, supplier margins, and worldwide alloy prices all affect the cost of EN24 round bars. As of 2023, certified material should cost between AED 25 and AED 45 per kg. For precise pricing, it is better to ask suppliers for a direct quote. 

Can EN24 round bars be welded? 

Yes, but proceed with caution. EN24 is prone to cracking if it is welded improperly because of its high carbon and alloy content. Almost invariably, pre-heating and post-weld heat treatment are required. Speaking with a welding engineer is advised. 

What is the difference between "black" and "bright" EN24 rounds? 

Black bars are hot-rolled and have a scaled surface. Bright drawn bars are cold worked after rolling, resulting in a smoother surface finish, tighter dimensional tolerances, and better machinability. Bright bars are more common for precision components. 

Where can I find a reliable supplier of EN24 round bars in Dubai? 

Black bars have a scaled surface and are hot rolled. After rolling, brightly drawn bars are cold worked, which improves machinability, tightens dimensional tolerances, and smoothes the surface finish. Precision components are more likely to have bright bars.
