EN24 round bar

817m40 steel rod suppliers in UAE

Power transmission gears, propeller shafts, and others required hard and high-tensile strength steel during the early 1900s. EN24, used as wrought steel for aircraft and automobiles until then, became the first choice for such applications because of its high strength in “T” condition. For over a century, EN24T steel has been used in many applications.

EN24 round bar made of such popular steel alloy for over 100 years. Since it has nickel and chromium around 1%, it has good corrosion resistance even at high temperatures. Up to 0.35%, molybdenum and 0.70% manganese make EN24 Steel Round Bar strong to be useful for many applications in the manufacturing sector and for structural components that need high tensile strength.

What does EN24 bars stand for?

EN24 was wrought steel to make many components for the aircraft and automobile industry during the early 20 century. Increasing its tensile strength and hardness by annealing or T condition became useful in many other industries like making structural and many other manufacturing components.

EN or emergency numbers for steel to identify during the second world war categorized these wrought steel with high strength as EN 24 bars. It is because of the medium carbon content between 0.36 to 0.44%. Among the many EN classifications, EN 24 is high-strength steel with 1% chromium, nickel, manganese, and molybdenum in less than one percent.

T condition in EN24 is the heat treatment to 850/1000 N/ mm2m. Compared to the “Z” condition of heat treatment, 1550 N/mm2it is more popular. It is because of its easy machinability, duct ability, and other properties. Hence EN24 Carbon Steel Rods are best for making components like studs, shafts, bolts, gears, etc.

EN24 in T condition or EN24T with further surface hardening by nitriding or induction process helps to make many components that require enhanced wear resistance. Heat treatment with varying levels can offer high tensile strengths between 800 to 1000 N/ mm2.

EN24 steel alloy with chromium, nickel, manganese, molybdenum, and less than 0.45% carbon is 817M40. It can be available also in the heat treated or T condition as 817M40T to have tensile strengths ranging from 850 to 1000 N/ mm2.

Reputed suppliers offer 817M40 plates of varying thicknesses from 10mm to 300mm. Diameters range from 100 to 900mm, and squares from 10 mm to 300 mm in thickness. And flats in the size of 20 x 10 to 3000 x 300 mm. 817m40t Steel Rounds in the T condition have good machinability for many manufacturing and structural applications.

Different types of En 24 round bar

EN24t bright bar provides good fatigue strength together with toughness and high strength.

EN 24 steel bright bar is one of the popular steel alloys with many enhanced properties in the T condition. The excellent machinability enables it to be available in many forms, like the EN-24 Square Bar. There are many uses for these EN24 carbon Steel Round bars, including the following.

• Best to make bolts, studs, gears, shafts, and other high-strength requiring machine tools.
• With enhanced surface hardening, it makes components withstand wear resistance.
• Used in many applications like special cranks, connecting rods swivel arms, stub axles, and others.

What is the difference between EN24 and EN24T bars?

EN24 has been one of the popular steel alloys for over a century. From being useful as wrought steel in making components for automobiles and aircraft, it is also useful for many applications that need high strength. It is because of its medium carbon content of 0.36% to 0.45%, with 1% nickel and chromium and less than 1% manganese and molybdenum.

EN24T is EN24 in the T or annealed condition with more enhanced properties. It includes excellent machinability, superior strength, and others. Hence it is useful in more applications than EN24. EN24t Rods are best for making shafts, gears, bolts, screwed parts, and others.

EN24, with low strength and hardness, is mostly mild steel. But in the T condition of EN24T condition, it is strong and hard and suitable for many applications. Hence in the EN24T condition, it is not mild steel. But the machinability in the T or annealed condition is 35 to 40% of the mild steel. But the Carbon Steel EN-24 Black Bar has approximately 53% machinability of the mild steel. Hence the answer to whether EN-24 CS Hex Bars is a mild steel bar is yes. But not in the T condition, which has superior strength and hardness and is useful in many applications in various sectors.
