Audited Supplier 42CrMo SAE4140 4130 Steel Plate is a commonly used alloy structural steel material composed of elements such as carbon, chromium, manganese, silicon, molybdenum, and iron. This material is widely used in various industrial fields due to its excellent mechanical properties.
Firstly, the main components of 42CrMo are carbon and chromium. The content of these two elements in the alloy is 0.38-0.45% and 0.9-1.2%, respectively. The presence of carbon can increase the hardness and strength of steel, improve its wear and corrosion resistance. The addition of chromium can improve the high-temperature resistance and oxidation resistance of steel, enabling it to maintain good mechanical properties in high-temperature environments.
Secondly, SAE4140 4130 Steel Plate also contains a certain amount of manganese. The content of manganese in the alloy ranges from 0.50 to 0.80%, and its addition can improve the toughness and impact resistance of the steel. At the same time, manganese also helps to control the grain size of steel, enabling it to have better processing performance and weldability.
In addition, SAE4140 4130 Steel Plate also contains a small amount of silicon. The content of silicon in the alloy is 0.17-0.37%, which mainly plays a role in de oxidation and increasing the hardness of the steel. Silicon can also improve the thermal stability and corrosion resistance of steel, extending its service life.
Finally, the molybdenum added to SAE4140 4130 Steel Plate is one of its unique components. The content of molybdenum in the alloy ranges from 0.15 to 0.25%. The addition of molybdenum in steel can significantly improve its strength, hardness, and hardness retention ability. In addition, molybdenum can also improve the thermal stability and oxidation resistance of steel, enabling it to have better performance in high temperature and corrosive environments.
In summary, SAE4140 4130 Steel Plate is an alloy structural steel composed of elements such as carbon, chromium, manganese, silicon, molybdenum, and iron. Its rich composition endows it with excellent mechanical properties and corrosion resistance, making it suitable for various industrial fields. SAE4140 4130 Steel Plate plays an important role in fields such as aviation, aerospace, automotive, mechanical manufacturing, petroleum, and chemical engineering. At the same time, SAE4140 4130 Steel Plate can also be processed and modified through processes such as heat treatment and surface treatment to meet the needs of different industries and scenarios. In summary, the excellent performance and wide application of 42CrMo make it one of the indispensable and important materials in today's material engineering.
Production process
The hot-dip galvanized hot-rolled sheet production line adopts the improved Sengimir annealing process, with the raw material being hot-rolled and pickled sheet coils. The production process is as follows:
Hot rolled pickling plate coil → uncoiling → cutting head and tail → welding → inlet looper → improved Sengimir method horizontal annealing furnace → hot galvanizing → cooling after plating → zinc layer thickness gauge → smooth leveling and straightening → passivation treatment → inspection table → electrostatic oiling → coiling → weighing and packaging → finished product warehousing.
