A240/SA-240, UNS S32101. This is a chromium, manganese, and nitrogen-strengthened duplex stainless steel with higher ultimate tensile and yield strengths than type 304 and 316 stainless steel. This material can be welded using a ma tching Duplex 2101 (2304 or 2209) filler metal by Alloy 310/310S Heat Resistant Stainless Steel Plate
- General PropertiesCorrosion ResistanceMechanical PropertiesAlloy 310 (UNS S31000) is an austenitic stainless steel developed for use in high temperature corrosion resistant applications. The alloy resists oxidation up to 2010oF (1100oC) under mildly cyclic conditions. Because of its high chromium and moderate nickel content, Alloy 310 is resistant to sulfidation and can also be used in moderately carburizing atmospheres. The more severe carburizing atmospheres of thermal process equipment usually require nickel alloys such as 330 (UNS N08330). Alloy 310 can be Microstructural Evolution and Mechanical Properties of Feb 02, 2013 · The paper discusses the effect of semi-solid processing on the microstructural evolution and mechanical property of 304L stainless steel. For the study, steel specimens were partially melted and cooled to room temperatures in different cooling medium. The effect of temperature, time and cooling medium on microstructural evolution was studied by using optical microscopy.

Jan 11, 2020 · Type 304L Stainless Steel Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion environments, and it eliminates the need for annealing. Weldability of Materials - Stainless Steel - TWIAn indication of the ferrite-austenite balance for different compositions is provided by the Schaeffler diagram. For example, when welding Type 304 stainless steel, a Type 308 filler material which has a slightly different alloy content, is used. Ferritic stainless steel. Ferritic stainless steels have a Cr content typically within the range 11
