When it comes to choosing between 45# seamless steel pipe and 40Cr steel pipe, understanding their unique properties is key. The 45# seamless steel pipe is widely recognized as a high-quality carbon structural steel, making it a popular choice among mold manufacturers who rely on its durability and reliability. On the other hand, the 40Cr steel pipe serves a broader range of applications. It’s commonly used to produce mechanical components that endure moderate to high levels of stress, such as automotive steering knuckles, rear axles, gears, and even some critical machine tool parts like splined shafts and collars.
After undergoing quenching and tempering at medium temperatures, this steel becomes even more robust, ideal for manufacturing components that must handle heavy loads, impacts, and moderate speeds. For instance, gears, spindles, and oil pump rotors benefit from these enhanced properties. When treated with quenching and low-temperature tempering, it can also be used for heavier-duty parts where low-load and wear-resistant requirements dominate, such as certain types of shafts or collars. Additionally, when subjected to high-frequency quenching, it excels in producing parts that require high surface hardness and abrasion resistance but face minimal impact, such as gears, sleeves, and crankshafts.
Beyond these core uses, the 40Cr steel pipe is also well-suited for carbonitriding treatments, particularly for large-diameter components like gears and shafts that need both strength and toughness at lower temperatures. This versatility makes it a go-to material across industries ranging from automotive to industrial machinery.
