Product Description

AISI SAE4140 is a high-quality alloy structural steel with excellent mechanical and processing properties. This type of steel is labeled as 4140 in the US steel grade system, while in China, it is equivalent to alloy structural steel 42CrMo. Correspondingly, the equivalent grade of SAE4130 steel from the United States in China is 30CrMo.
The strength and hardenability of ASTM 4140 alloy steel plate are very high, which means it can maintain its structural integrity under high pressure and stress environments. At the same time, its toughness is also very good, which means it can maintain its shape under impact or bending without fracture or damage. These characteristics make 4140 an ideal choice for manufacturing high-strength mechanical and structural components.
During the quenching process, the deformation of 4140 alloy steel plate is very small, which makes it very useful in manufacturing precision mechanical parts. Due to its good dimensional stability, its shape and size hardly change after quenching and tempering. This is very important for parts that require high-precision manufacturing.
The chemical composition of 4140 alloy steel plate is precisely controlled to ensure its excellent mechanical properties. Among them, the carbon content is controlled between 0.33% and 0.48%, which helps to improve the strength and hardness of the steel. The silicon content ranges from 0.15% to 0.35%, which can improve the toughness and corrosion resistance of steel. The content of manganese ranges from 0.75% to 1.00%, which helps to improve the strength and hardenability of steel. The content of sulfur and phosphorus is controlled at very low levels to ensure high purity and excellent mechanical properties of the steel. The chromium content is between 0.80% and 1.10%, which can improve the hardness, wear resistance, and corrosion resistance of steel. The content of molybdenum ranges from 0.15% to 0.25%, which can improve the strength, toughness, and fatigue resistance of steel.
Due to its excellent mechanical properties and chemical composition, 4140 alloy steel plate has been widely used in many industries. For example, in the oil and gas industry, it is used to manufacture high-strength and corrosion-resistant components such as oil pipes, drill rods, and wellhead equipment. In the aerospace industry, it is used to manufacture engine components and structural components for aircraft and rockets. In addition, 4140 seamless steel pipes are also widely used in industries such as automobiles, mechanical manufacturing, power, and chemicals.
4140 alloy steel plate is a high-quality alloy structural steel, whose strength, hardenability, toughness, and chemical composition are precisely controlled to ensure its excellent mechanical and processing properties. This type of steel is widely used in multiple industries and is an ideal choice for manufacturing high-strength and highly corrosion-resistant mechanical and structural components.
