Housings and frames can be furnished in all stainless steel, aluminum or Monel. The exact grade of metal used depends on the nature of the installation. Unless otherwise specified, #304 housings will be furnished when stainless steel is ordered. #316 stainless steel is also available. All Hartzell fans and blowers for corrosive applicationssp.info Atmospheric Corrosion Resistance of Stainless Steel Feb 15, 2016 · Two main factors that affect atmospheric corrosion resistance and cosmetic degradation of stainless steel are the environmental conditions and the characteristics of the stainless steel used. Environmental factors, such as temperature, rainfall, relative humidity and the presence of aggressive species (of which the most harmful is the chloride ion), are very important for the selecting stainless steel.sp.info Corrosion resistance levels in stainless steel - Ryerson

  • MartensiticFerriticAusteniticIn general, martensitic stainless steels are considered ‘moderate’ when it comes to corrosion resistance. Like low alloy or carbon steels, martensitic stainless steels are similar in structure to ferritic, but can be hardened or strengthened by heat treatment—which can also make them more brittle. This is due to the addition of carbon. The main alloying element of this family is chromium. The oil industry is a heavy user of martensitic stainless steel, as is the medical field—primarily for surgical equipment. Among the mosThe Corrosion of Stainless Steels in the AtmosphereThe resistance of stainless steels to degradation in the atmosphere was directly related to alloy chromium and molybdenum contents. Only American Iron and Steel Institute (AISI) Type 410 showed any signs of corrosion in the semirural environment. Significant corrosion product tarnishing occurred on all nonmolybdenum-bearing stainless grades sp.info GALVANIC CORROSION STUDY ON STAINLESS STEEL
