PRODUCT DESCRIPTION
|
PRODUCT INTRODUCTION
42CrMo carbon steel sheet is a low-alloy, high-strength steel grade known for its outstanding mechanical properties, including high tensile strength, good hardenability, and excellent toughness under impact loads. It belongs to the Chinese standard GB/T 3077, and is equivalent to AISI 4140, DIN 1.7225, or EN 42CrMo4.
This steel sheet is often supplied in normalized, quenched and tempered conditions, providing reliable performance for structural components and precision-machined parts that require strength, toughness, and resistance to fatigue.

42CrMo steel exhibits good mechanical processing adaptability and supports conventional processing technologies such as drilling, milling, and broaching, but special attention should be paid to the welding process: welding can be carried out in the annealed state, while welding in the quenched and tempered (QT) state will change the mechanical properties of the heat-affected zone. If QT welding is necessary, the workpiece must be immediately cooled and stress relieved at 15°C below the original tempering temperature. This material can adjust the performance range through a flexible heat treatment solution. It is an economical solution to replace high-end alloy steels, and is particularly suitable for industrial scenarios with strict requirements on material strength, temperature resistance, and impact resistance.
