EN24 Alloy Hot Rolled Steel Bar

EN24 Alloy Hot Rolled Steel Bar

1: EN24 Steel Introduction

EN24 is a high-strength alloy steel with extremely high mechanical properties and wear resistance, as well as extremely high tensile and yield strengths, typically in the range of 900-1100 MPa. EN24 alloy steel has excellent fatigue resistance, which allows it to maintain its reliability and integrity over long periods of time under heavy-duty operating conditions. Maintaining high toughness along with high strength reduces the risk of cracking in areas of stress concentration and increases bendability, making it more suitable for complex loading and impact situations.

5: EN24 Steel Mechanical Properties 

The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

12: Packing& Delivery

For the delivery, we will choose LCL, FCL and Bulk carrier according to order quantity. Usually if the quantity is less than 10tons, we will recommend LCL. If the quantity is more than 100tons, we will recommend bulk carrier. Usually FCL will be the most common for delivery.

In order to better ensure the safety of your goods, we will provide professional, environmentally friendly, convenient and efficient packaging services. Such as pallet, wooden box, package with woven bag etc.

13: EN24 Steel Heat Treatment

Normalizing

The temperature is generally 820-860°C. This step helps to improve the organization and properties of the steel.

Quenching

Again at a temperature of 820-860°C. Quenching is the process of hardening steel by rapid cooling, thereby increasing its hardness and wear resistance.

Tempering

The temperature range is 550-660°C. Tempering is used to stabilize the steel and reduce internal stresses, while maintaining the hardness obtained after quenching and improving the toughness of the steel.

14: EN24 Steel Application

Automotive industry: for the manufacture of key components such as crankshafts, axles, gear shafts, etc.

Aerospace industry: for the manufacture of aircraft components requiring precision and strength.

Manufacturing industry: for the production of gears, shafts and structural components.

Construction industry: for structural elements subject to heavy loads.

Oil and gas industry: for applications such as drill pipes.

15: Delivery Condition

For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed or QT, black surface or rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed or QT, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed or QT, black surface.
