EN10305-1 E215 NBK Round Seamless Precision Steel Pipe for Automotive

Product Description

EN10305-1 E215 NBK Round Seamless Precision Steel Pipe for Automotive

TORICH is a professional manufacturer and exporter of precision steel pipes. Cold-drawn precision seamless steel

pipe is used for high dimensional precision and good surface finish of mechanical structure and hydraulic equipment.

Size range: O.D.:6-420mm W.T.:1-50mm L:max12000mm

Production: Cold Drawn + Cold Rolling

Our regularproduction size: 60x50 42x3.2mm

Steel Grade and Chemical Compositions:

Available Surface Treatment:

Galvanization/Galvanized/Zinc Coated

Blue White Zinc (Trivalent Chromium Passivation)

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
