JIS SCM440 steel is a premium low alloy steel, recognized for its outstanding properties such as toughness, fatigue strength, and abrasion resistance. This steel is highly valued in the manufacturing sector for its ability to withstand heavy loads and endure demanding conditions. It is extensively used in the production of critical components such as gears, shafts, spindles, and tool bodies, where strength and durability are important.

From the factory of Dongguan Songshun Mould Steel Co. Ltd., JIS SCM440 steel is composed of chromium, molybdenum, and manganese, enhancing its mechanical properties. The steel’s higher carbon content contributes to its excellent heat treatment capabilities, allowing it to be oil-hardened for improved hardness and strength.

AISI 4140 Steel Characteristics
1. It is low alloy steel with chromium, molybdenum, and manganese.
2. Great toughness, fatigue strength, abrasion and impact resistance.
3. It is widely be used in the industry due to its excellent versatility and usefulness.
4. The higher carbon content in it, the higher the strength and heat treatment capabilities it is.
5. It can be oil hardened to relatively high hardenability.

This makes JIS SCM440 an ideal choice for applications that require resistance to wear and impact, such as engine parts, suspension components, and other vital machinery parts.
