ASTM A513 Carbon Steel Mechanical Tubing Manufacturer – Huagang Industrial
ASTM A513 is the standard specification for carbon and alloy steel mechanical tubing. Unlike structural piping, A513 tubing is preferred for applications requiring tight dimensional tolerances, excellent surface finishes, and specific mechanical properties. At Huagang Industrial, we specialise in producing high-precision A513 tubing tailored to your fabrication needs-whether for bending, flanging, or machining.
Choosing the Right A513 Type
Type 1 (Hot-Rolled ERW):
Most economical. Ideal for structural applications where surface finish is not critical.
Best for: Framework, agricultural equipment, and hidden structural parts.
Type 2 (Cold-Rolled ERW):
Superior surface finish and tighter wall thickness tolerance than Type 1.
Best for: Exposed parts, furniture, display racks, powder coating applications.
Type 5 (DOM - Drawn Over Mandrel):
Huagang's Specialty. The weld flash is removed, and the tube is cold drawn. This creates a seamless-like surface, precise concentricity, and high strength.
Best for: Hydraulic cylinders, automotive bushings, motor housings, telescopic cylinders.
Why Source A513 Tubing from Huagang Industrial?
Export Ready: Expert packaging (wooden crates, plastic caps) to prevent rust and damage during sea freight.
Quality Assurance: In-house Eddy Current testing, flattening tests, and dimensional checks.
Custom Fabrication: We offer cutting-to-length, deburring, and bending services.
Competitive Lead Times: Large inventory of raw coils ensures fast production turnover.
Applications of ASTM A513 Tubing
Our ASTM A513 steel tubes are trusted by industries worldwide:
Automotive: Steering columns, shock absorbers, exhaust systems, roll cages.
Agriculture: Tractor frames, grain augers, fencing.
Construction: Scaffolding, structural columns.
Consumer Goods: Fitness equipment, metal furniture, bicycle frames.
Machinery: Conveyor rollers, hydraulic cylinders (DOM).

Cold drawn / soft | +LC (BKW) | After the last heat treatment, follows the cold drawing there is a light finishing pass. |
Cold drawn and stress relieved annealed | +SR (BKS) | After the final cold drawing process, the tubes are stress-relieved and annealed in a controlled atmosphere. |
Annealed | +A (GBK) | After the last cold drawing process, the tubes are annealed in a controlled atmosphere. |
Normalized | +N (NBK) | After the last cold drawing process, the tubes are normalized in a controlled atmosphere. |
Quality Control
Strict Testing Chemical composition analysis: Ensure that the material composition meets the standard requirements. Mechanical performance testing: Including tensile testing, impact testing, etc., to ensure that the steel tube has sufficient strength and toughness. Non destructive testing: Using ultrasonic, eddy current, or radiographic testing techniques to detect internal defects in steel tubes. Hydraulic test: Each steel tube undergoes a hydraulic test to ensure good sealing and pressure bearing capacity in high-pressure environments. | Testing Standards Compliant with international standards such as GB3087, DIN17175, ASTM A53, ASTM A519, ASTM A106, ASTM A179, ASTM A192, etc. Each batch of products comes with detailed quality inspection reports and certificates of conformity. | Certification Guarantee Obtained ISO/TS16949:2009 quality system certification and obtained the national special equipment pressure pipeline component manufacturing license. |
