Sep 01, 2000 · This specification covers a corrosion-resistant steel in the form of sheet, strip, and plate. These products have been used typically for parts requiring high strength and corrosion resistance from -423 to +1100 °F (-253 to +593 °C), where such parts may require welding during fabrication, but usage AWS 5.9 ER308/ER308H/ER308L Welding Rod - Welder metalsAWS A5.9 /ASME SFA5.9 is the specification for welding consumables:wire, electrodes, and rods for arc welding of stainless and heat-resisting steels. Class ER308/ ER308L/ ER308H Welding Rods are used extensively for GMAW, GTAW and SAW welding of 18Cr-8Ni, 19Cr-9Ni and 20Cr-10Ni stainless steel such as 304, 304L and 304H materials.
steel. Both the TIG- rod and the weld deposit satisfy highest quality requirements. Base materials 2.4816 Ni Cr 15 Fe, 2.4817 LC-NiCr 15 Fe, Alloy 600, Alloy 600 L Nickel and nickel alloys, low-temperature steels up to 5% Ni-steels, unalloyed and alloyed, high Development of Manufacturing Process of PNC-FMS and was welded to a SUS316 steel plate by TIG welding using a Ni20Cr alloy welding rod (1.2mm in diameter) as shown in Table 1 (SUS316-1 and Ni20Cr). A Ni20Cr welding rod was used to prevent the diusion of elements (C and Ni, in particular) in the interface between the ferritic and austenitic steels. Normalizing, as the rst step heat
Welding of the early superaustenitic alloy, 904L, was often carried out satisfactorily with matching composition welding consumables. However as the alloying content is increased, so does the segregation of molybdenum in the as-cast weld metal microstructure such that the weld metal corrosion resistance falls well below that of the parent steel.

Generally, heat treatment is not required after welding, but parts with a thickness greater than 15mm need to be preheated to 100-150°C before welding, and tempering heat treatment is not required after welding. 20Cr steel plate application range Metals and how to Weld Nickel AlloysInconel 625 welding wire is used routinely to weld layers of heat and corrosion resistance cladding on less corrosion resistant steel . It stands to reason that if inconel 625 can be used to clad steel or chromium steel boiler tubes, it is also a good choice as a welding rod for welding steel to other metals.
