Standard ASTM A519
Matrial AISI4130 AISI4140
Size OD: 6-350mm WT: 1-50mm Length: 1-12m
Manufacture Tubes are made by seamless process.
At the manufacturer's option, tubing may be furnished either hot finished or cold finished.
Condition
Sizing Methods		 1. Hot-Finished Mechanical Tubing
2. Cold-Worked Mechanical Tubing
3. Rough -Turned Mechanical Tubing
4. Ground Mechanical Tubing
Thermal Treatment: 1. A-Annealed
2. N-Normalized
3. QT-Quenched and Tempered
4. SR-Stress relieved or Finish Anneal
The tubes shall be pickled free of scale,. When bright annealing is used, pickling is not necessary.
Workmanship, Finish, and Appeaerance The tubing shall be free of laps, cracks, seams, and other defects as is consistent with good commercial practice.
The surface finish will be compatible with the condition to which it is ordered.

QUALITY CONTROL:

1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing and Cold Rolling, on line inspection
5. Heat Treatment, +A, +SRA, +LC, +N, Q+T
6. Straightening-Cutting to specified length-Finished Measuring Inspection
7. Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8. Packing and Stocking

100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate longitudinal and transversal defects.
