Description

45# Seamless Steel Pipe is a high-quality carbon structural steel piping solution manufactured from 45# grade steel, which corresponds to international standards such as AISI 1045 or DIN C45. Renowned for its high strength and hardness, this pipe is produced through precise hot-rolling or cold-drawing processes to ensure a uniform microstructure and excellent dimensional accuracy. With a carbon content of approximately 0.45%, it offers superior mechanical properties compared to low-carbon steels like 20#, making it the material of choice for applications requiring robust load-bearing capabilities and wear resistance.

Key Features

• High Strength and Hardness: The 45# grade steel provides exceptional tensile strength (≥600 MPa) and yield strength (≥355 MPa), making it suitable for heavy-duty mechanical applications.

• Excellent Machinability: While harder than low-carbon steels, 45# steel maintains good machinability, allowing for precision turning, milling, and drilling to create complex mechanical parts.

• Superior Wear Resistance: The material's inherent hardness offers better resistance to abrasion and surface wear, extending the service life of components in dynamic environments.

• Good Toughness: Despite its high strength, the pipe retains sufficient toughness to withstand impact loads without fracturing, especially after appropriate heat treatment like normalizing or quenching.

• Versatile Fabrication: It can be easily welded (with preheating) and formed, providing flexibility in manufacturing processes for various industrial components.

Applications

• Mechanical Manufacturing: Widely used for producing shafts, gears, connecting rods, and other high-stress mechanical parts that require high surface hardness and core toughness.

• Hydraulic Systems: Ideal for manufacturing hydraulic cylinders and pneumatic barrels due to its ability to withstand high internal pressures.

• Automotive Industry: Employed in the production of axles, steering components, and transmission parts where durability is critical.

• Construction Machinery: Used for structural supports and pivot points in heavy equipment like excavators and cranes.

• General Engineering: Suitable for manufacturing bolts, studs, and fasteners that demand high tensile strength and reliability.
