GRINDING & POLISHING

Grinding:

As INOX Surface Treatment B.V we advise to avoid as much as possible mechanical surface treatment for stainless steel (Grinding / blasting etc.) to keep surface in original status as specified.

Nevertheless for newbuilding constructions welding /bending cutting etc. will take place and even with the best protection and precautions to avoid any damage / corrosion there will be always the need for mechanical treatment of damages / HAZ ( heat affected Zones ) / impurities etc. , prior to chemical/technical cleaning by pickling/passivating , which is necessary to restore the corrosion resistant passive layer ( Cr2O3). And ship will be ready for all cargoes.

For ships in services / used objects which need to be restored / upgraded because of corrosion / discolorations / cargo residue etc. first we will always try to solve these cases by chemical technical cleaning. (Testing with several chemicals to find out the best result and cleaning procedure in advance)
The advantage: No staging / no high labor costs / not many delays.

If this turns out not to be effective and the only final procedure for a good end result is mechanical cleaning, then our experienced teams are ready to for fill these works with own equipment and materials if required.

Note: Corroded (pitting / rough areas / elephant skin) surfaces cannot be restored to original / lower roughness by chemical/technical cleaning. The only way is mechanical cleaning by grinding/polishing.
Especially for cladd steel (2 – 3 mm Stainless steel layer) we advise to execute these grinding/polishing works by our experienced teams or supervisors.
