Product description:

Precision seamless pipe is a type of steel pipe formed by punching through round steel, with no welds on the surface. According to the production method, seamless steel pipes are divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, and hot-expanded seamless steel pipes. Seamless steel pipes are classified into two types based on their cross-sectional shape: circular and special-shaped.

1045 Precision Seamless Steel Tube is a high-quality carbon steel tube manufactured through advanced cold drawing or cold rolling processes to achieve exceptional dimensional accuracy, mechanical strength, and surface finish. Made from AISI 1045 medium carbon steel, this tube offers an ideal balance between strength, toughness, and machinability, making it a preferred choice in mechanical, hydraulic, and automotive engineering applications that demand high precision and reliability.

Material Overview

AISI 1045 steel is a medium carbon steel containing approximately 0.45% carbon, which provides superior strength and hardness after heat treatment while maintaining good machinability. It exhibits excellent wear resistance, impact toughness, and fatigue strength. This makes 1045 precision seamless tubes ideal for components that must endure high mechanical stress, such as shafts, hydraulic cylinders, and machinery parts.

Manufacturing Process

The production of 1045 precision seamless steel tubes begins with high-quality hot rolled seamless pipes, which are then subjected to cold drawing or cold rolling to achieve tighter dimensional tolerances and a smoother surface. The process typically includes:

Cold drawing or cold rolling: Reduces the tube diameter and wall thickness with precision control.

Heat treatment (annealing or normalization): Improves ductility and relieves internal stress.

Straightening and sizing: Ensures perfect roundness and uniform wall thickness.

Surface treatment: Produces a clean, bright, or phosphated finish depending on the application.

The result is a high-precision seamless tube with consistent mechanical performance, accurate dimensions, and excellent surface quality.

Key Features

High dimensional accuracy: Outer diameter tolerance up to ±0.05 mm.

Smooth internal and external surfaces: Ideal for hydraulic and pneumatic systems.

Excellent strength and toughness: Suitable for heavy-duty mechanical applications.

Good machinability: Compatible with cutting, drilling, threading, and welding operations.

Improved fatigue resistance: Withstands cyclic stresses under dynamic loads.

Customizable sizes and lengths: Available in a variety of specifications upon request.

Applications:

The application scope of seamless steel pipes is very wide, including structures, fluid transportation, low to medium pressure boilers, high-pressure boilers, fertilizer equipment, petroleum cracking, geological drilling, diamond core drilling, petroleum drilling, ships, automotive half-shaft sleeves, diesel engines, etc. The use of seamless steel pipes will ensure no leakage problems, guarantee the usage effect, and improve material utilization. It can be seen that the application of seamless steel pipes mainly covers three major fields. The first is the construction field, which can be used for underground pipeline transportation, including extracting groundwater during construction. The second is the processing field, which can be used for mechanical processing, bearing sleeves, etc. The third is the electrical field, including gas pipelines and fluid pipelines for hydropower generation.

1045 precision seamless steel tubes are widely used in:

Hydraulic and pneumatic systems: Hydraulic cylinder barrels, precision pistons, and pressure components.

Automotive industry: Drive shafts, steering systems, and engine parts.

Mechanical engineering: Machinery spindles, gears, rollers, and bearing sleeves.

Construction and mining equipment: Structural tubes, lifting arms, and machine frames.

Energy and transportation: Power transmission shafts and industrial machinery components.

The combination of precision, strength, and surface quality ensures reliable operation and long service life in demanding industrial environments.
