SAE 4140 Plate & Sheets
SAE 4140 Plate (AISI 4140) is one of the most popular direct hardening Cr-Mo Alloy Steel Plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel.
Alloy Steel AISI 4140 Plate is widely used for general purpose industrial machining. Welding and forming of this steel plate should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary.
4140 steel is a Chromium Molybdenum alloy steel known for its high tensile strength and toughness. It’s often used in applications where strength and impact resistance are crucial.
We can offer AISI 4140 in bar form from stock, rolled and bright drawn, also plate. It is renown for its wear resistance and where high strength properties is required. Suitable for gears, shafts, spindles, etc. Frequently used within the gas and oil industry. For improved weldability consider using 4130.
4140, EN19, 42CrMo4, 1.7225 is a versatile heat-treated steel, which is characterized by its high strength and toughness. It is mainly used in mechanical engineering, and for vehicle and automotive use. Gear, crankshafts and connecting rods are manufactured from it.
EN19 Alloy Steel, also known as 4140 steel or 1.7225 steel, is a common chromium-molybdenum steel with high density, and high hardenability, usually used after tempering. 42CrMo4 quenched steels have better performance than 34CrMo4 steels due to higher carbon and chromium content. 4140 steel has higher strength and hardenability in terms of its properties. The properties of AISI 4140 steel include high strength and good low-temperature impact toughness. Therefore, its machinability is high.
Applications :
- • Back-up and support tooling
- • Fixtures
- • Gears and gear racks
- • Machinery parts and components
- • Mold bases
Benefits of Using EN19 / 4140 material
• Strength : It’s incredibly strong, making it perfect for heavy-duty applications.
• Toughness : It can withstand impact without breaking or deforming.
• Machinability : Despite its strength, it’s relatively easy to machine.
