Corrosion Prevention and Management of Welds Virtual A few corrosion studies performed to establish welding code and standard requirements will be reviewed, such as selection of filler metals for 6% molybdenum stainless steels and establishment of stainless steel weld discoloration levels in the pharmaceutical industry based on corrosion testing. Corrosion Standards and Wear Standards - ASTMCorrosion Standards and Wear Standards. ASTM's corrosion and wear standards provide the appropriate procedures for carrying out corrosion, wear, and abrasion tests on specified metallic materials and alloys. These tests are conducted to examine and evaluate the behavior, susceptibility, and extent of resistance of certain materials to stress
the weld procedure. It may also adversely affect weld HAZ corrosion performance, albeit under extreme service conditions:Nitrogen can diffuse rapidly from the 6%Mo HAZ to the weld metal and result in the formation of niobium nitrides at the weld deposit fusion boundary, leading to some loss of ductility and corrosion resistance. Ferritic Stainless Steel - an overview ScienceDirect TopicsP. Lambert, in Sustainability of Construction Materials (Second Edition), 2016 6.3.1 Ferritic stainless steel. Ferritic stainless steels are magnetic, non-heat-treatable steels that contain 1130% chromium but little or no nickel. They are typically employed for nonstructural applications where there is a requirement for good general corrosion resistance or good stress corrosion resistance Grade 304 Stainless Steel Properties, Tensile Yield The high nickel-chromium alloy content gives it excellent corrosion resistance and is widely used in the food industry as a standard food grade stainless steel. There are several variants of 304 grade stainless steel, such as ultra-low-carbon version type 304L , nitrogen-containing version 304N, 304H with improved creep performance, and type

WELDING OF STAINLESS STEELS 1.0 INTRODUCTION Stainless steels are defined as iron base alloys which contain at least 10.5% chromium. The thin but dense chromium oxide film which forms on the surface of a stainless steel provides corrosion resistance and prevents further oxidation. There are five types of stainless steels depending on the other
