6. Manufacturing Process of Stainless Steel Sheet/Plate:

Raw materials are sending to hot rolling units for rolling into different sizes.
→Hot rolled material is annealing in cold rolled annealing furnace and pickling in acid.
→All mill rolls are grinded on precision grinding machine with proper chamfering after first shift operation.
→All sheets are pickled in different tanks and dried on brush roll machine before dispatched.
→These sheets are again annealing and are sent to straighten machine for straightening.
→Inspections are done at various stages. Keep proper control overall internal process via rolling, annealing and pickling by our experienced staff.

7,Stainless steel maintenance:

(1) Regular clea ning and maintenance

(2) Pay attention to prevent the occurrence of the phenomenon of surface scratches

(3) Use soap, weak detergent or warm water to remove surface dust, dirt

(4) In addition to the surface of the binder with alcohol or an organic solvent (ether, benzene)

(5) Use neutral detergent or ammonia solution in addition to surface oil

(6) With 10% nitric acid or abrasive detergent in addition to the surface of the embroider caused by the dirt.
