Technical Information

For any stainless steel to provide peak performance a number of factors must be considered as a part of the specification process,

  • Application – Consider effects from / on the surrounding environment, establish performance expectations, and life cycle cost analysis.
  • Design – design to eliminate stresses, crevices, and corrosion sites. Use appropriate codes and standards.
  • Material Selection – Identify correct material grade, surface finish, product type, material condition, availability, etc.
  • Fabrication – Use quality materials, tools free from iron contamination, appropriate welding procedures, post weld surface treatments and polishing, and protect surfaces prior to installation.
  • Installation – Use tools free from iron contamination, keep surfaces protected for as long as possible until final commissioning.
  • Maintenance and Cleaning – Contrary to the popular misconception, stainless steel is “low maintenance”, not “no maintenance”. A simple cleaning regime can ensure many years of superb performance.
