Excellent Performance Bs 708m40 Alloy Material Best Supply - China

BS 708M40 alloy material is an alloy structural steel in the British Standard (BS), equivalent to 4140 steel in the international standard (AISI/SAE 4140 in the United States, DIN 1.7225 in Germany), and belongs to the category of chromium-molybdenum steel (Cr-Mo steel).

Its chemical composition is based on carbon (C), with the addition of alloying elements such as chromium (Cr) and molybdenum (Mo).

Through appropriate heat treatment process, it can obtain excellent comprehensive mechanical properties.

BS 708M40 alloy material core advantages:

- **Balance of high strength and high toughness**: Through quenching and tempering treatment (quenching + high temperature tempering), a fine tempered troostite structure can be obtained, which has both high strength and impact resistance.

- **Good hardenability**: Chromium and molybdenum elements significantly improve the hardenability of steel.

Even parts with larger cross-sectional dimensions can obtain a deeper effective hardened layer after quenching.

- **Wear resistance and fatigue resistance**: Alloy elements form carbides to improve surface hardness and wear resistance; at the same time, the uniformity of the organizational structure reduces the initiation of fatigue cracks.

- **Processability**: The cutting performance is good, and the surface hardness can be further improved by surface quenching (such as induction quenching).

BS 708M40 alloy material occupies an important position in high-end machinery manufacturing, energy, military industry and other fields due to its excellent comprehensive performance, and is a classic material choice for high-strength structural parts.
