Plating Colour Zinc(Trivalent Chromium Passivation)
Yellow, Army-Green
Phosphated/Black Phosphated
Main Features:
a.Rm: tensile strength; ReH: upper yield strength; A: elongation after fracture
b.1Mpa=1N/mm2 Depending on the degree of cold work in the finishing pass the yield strength may nearly be as
high as the tensile strength.
c. For calculation purposes the following relations are recommended:
for delivery condition +C: ReH ≥0.8 Rm
for delivery condition +LC: ReH ≥0.7 Rm
d.For calclulation purposes the following relation is recommended:ReH≥0.5Rm
e.For tubes with outside diameter ≤30mm and wall thickness ≤3mm the ReH minimim values are 10Mpa lower than
the values given in this Table
f.For tubes with outside diameter>160mm: ReH≥420Mpa
Surface quality: Without oxidization, No crack, No fold, No rolling fold, No scar, No laminar defect

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
