Stainless steel processing requires the necessary knowledge and specialisation. Alinco has been working with stainless steel for more than 30 years. During this time we have accumulated a considerable amount of knowledge and have continued to raise the bar even higher. Working with stainless steel is second nature for us but we still encounter misunderstanding on a regular basis when it comes to corrosion or rust formation, stainless steel qualities and finishing options.

Our 10 commandments

As specialists in the subject, we are of course familiar with the DO’s and DON’Ts of stainless steel.
Here are 10 tips for working correctly and sensibly with stainless steel.

  1. Avoid contact between iron and stainless steel (risk of contamination and therefore corrosion).
  2. Use non-ferrous tools. Do not use steel knives or nails to cut the protective film - use suitable tools.
  3. To grind or polish stainless steel, use grinding wheels and abrasives meant for stainless steel, preferably those based on aluminium-zirconium oxide or silicon carbide. Do not mix tools. Above all, do not grind stainless steel using a wheel that has already ground steel sheet.
  4. Always process iron and stainless steel separately. If this is not possible (e.g. in a building under construction), protect the stainless steel from iron contamination. Give the necessary instructions to the builder or end customer. Ban steel grinding close to stainless steel.
  5. Avoid surface damage. Any damage provides a location where dirt can collect and increases the risk of corrosion.
  6. Use suitable cleaners for final finishing and give the end customer correct instructions for  maintenance.
  7. Make sure you purchase material of the right stainless steel quality. RVS 304 is generally specified for internal use in kitchens and food companies. RVS 316 or a different quality is required for outside use and in aggressive environments.
  8. Buy your material from a company specialised in stainless steel. Buying it from someone who mainly processes iron or does not have separate areas for processing is asking for trouble in the future.
  9. Examine for corrosion, even small amounts, and take steps to remove it.
  10. If in doubt, get advice from Alinco.
