Frequently Asked Questions About Alloy Steel EN24 Round Bar

EN24 round bars can be welded, but special care is required. Due to their high strength and alloy composition, pre-heating before welding and stress-relieving after welding are generally recommended to avoid cracking. Using proper welding electrodes and controlled conditions ensures better results.

EN24 is a high-strength nickel-chromium-molybdenum alloy steel. It is known for its excellent combination of tensile strength, toughness, ductility, and wear resistance, making it ideal for heavy-duty engineering applications.

The main difference lies in the heat treatment condition. EN24 refers to the base alloy steel grade, while EN24T is the heat-treated (tempered) condition of the same grade. EN24T has higher tensile strength, hardness, and toughness compared to untreated EN24, making it suitable for components exposed to extreme stress and impact.
