ADVANTAGE

*Good abilities of stress corrosion, all kinds of localized corrosion,antioxidant corrosion(including high temperature oxidation resistance).

*Low density

*Good thermal conductivity: It is 30%-50% higher than Austenite. Small coefficient of thermal expansion: It is 30%-40% less than Austenite.

*Big elastic modulus

*Good processing properties

*Easily bending, stamping, curling, pinin, cold forging and machining.

*Excellent deep drawability

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.
