    Guidelines for the selection of the correct stainless steel grade in structural applications according to the service environment: Euro Codes 1 to 4 provide a procedure for selecting the appropriate grade of stainless steel for the service environment of structural members. The environment is assessed using Corrosion Resistance Factor (CRF) and the stainless grades are placed in Corrosion Resistance Classes (CRC) I, I, III, IV & V according to CRF value.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
