20# Precision Honed Tube
20# Steel Precision Honed tube is a high-quality cold drawn seamless steel tube that undergoes a specialized finishing process known as honing. The "20#" designation refers to a Chinese standard (GB/T 699) for high-quality carbon structural steel, which is approximately equivalent to ASTM A513 Type 5 or SAE 1020 steel. This combination of material and precision manufacturing results in a product renowned for its excellent mechanical properties, tight dimensional accuracy, and superior internal surface finish.

Material Properties: 20# Steel
20# steel is a popular choice for honed tubes due to its balanced composition:
Good Strength and Toughness: It offers an optimal blend of strength and ductility, making it suitable for high-pressure applications.
Excellent Machinability: Its carbon content (around 0.17-0.24%) allows for easy cutting, welding, and further processing.
Uniform Microstructure: Provides consistent hardness and performance throughout the tube length.
Manufacturing Process
The production of 20# Honed Tubes involves two critical stages:
Features & Advantages
Typical Applications
20# honed tubes are the preferred component in systems requiring reliable and efficient linear motion:
Packaging and Quality Assurance
These tubes are typically supplied with plastic end caps to protect the精密 honed inner surface from damage, moisture, and contaminants during transport and storage. Quality is ensured through strict compliance with international standards such as DIN 2391, ASTM A513, and GB/T 3639.
