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.
