Technical Note: Exact dimensions, tolerances, heat-treatment condition, surface finish, applicable standard, and mechanical requirements should be confirmed against the purchase specification or technical drawing before production.
20# carbon steel is commonly used for general engineering and mechanical applications where a carbon steel material with suitable machinability and mechanical properties is required. Final material suitability should be verified against the application specification.
The seamless manufacturing structure eliminates a welded seam along the tube body, making it suitable for applications where seamless tubing is specified for mechanical or engineering requirements.
Precision tubing is selected when controlled outer diameter, wall thickness, straightness, and dimensional consistency are important for assembly or subsequent machining.
The tube can be used as a raw material for machining, forming, cutting, or other manufacturing processes when the confirmed material and dimensional specifications are appropriate.
Hydraulic Equipment
Suitable for compatible hydraulic components and systems where seamless precision tubing is specified.
Mechanical Machinery
Can be used for shafts, sleeves, cylinders, structural components, and other machined parts depending on the required dimensions and mechanical properties.
Automotive & Transportation Components
Applicable to compatible mechanical components where controlled tube dimensions and seamless construction are required.
Industrial Equipment
Used as a material for equipment components, fabricated assemblies, and precision-machined parts.
OEM Manufacturing
Equipment manufacturers can specify tube diameter, wall thickness, length, tolerance, heat treatment, and surface condition according to their production requirements.
MRO & Replacement
Distributors and maintenance buyers can source replacement tubing according to existing component dimensions or technical drawings.
For steel distributors, industrial wholesalers, and stockists, we support repeat procurement based on confirmed material, dimensions, standards, packaging, and delivery requirements.
For machinery production, engineering projects, hydraulic equipment, and industrial manufacturing, bulk quantities can be supplied according to confirmed specifications and production schedules.
For OEM applications, we can review drawings and technical requirements covering diameter, wall thickness, length, tolerance, surface condition, heat treatment, and other confirmed specifications.
Hanyang Machinery provides engineering-oriented manufacturing and industrial material supply. Depending on the confirmed requirements, support can include:
Drawing and specification review
