Welding Metallurgy of Heat Resisting Steels,t with regard to the scaling resistance. There exist ferritic, ferritic-austenitic und austenitic heat resisting steels. The latter contain higher amounts of nickel, normally in the range of approx. 4–35%. A comprehensive survey of the effect of alloying elements and scaling behaviour in different c背信 发表于 2025-3-25 08:48:49
Welding Metallurgy of Austenitic-Ferritic Dissimilar Joints, steels to austenitic chromium-nickel-(molybdenum) stainless steels. Such dissimilar joints are also called “black-and-white joints”. With regard to corrosion resistance, there are normally no particular requirements demanded from this type of joint, because the low alloyed steel is normally not corBRIEF 发表于 2025-3-25 14:00:41

Metallurgical Processes Occurring During Solidification and Cooling in Stainless Steel Weld Metal, cooling rate and the short time span this reheating is in no way comparable to the controlled heat treatment processes of steels. Furthermore, only part of a previously laid pass is influenced in this way and the rest is maintained as a solidification structure.OUTRE 发表于 2025-3-26 02:04:18

Welding Metallurgy of Duplex Austenitic-Ferritic Stainless Steels,y in the welded joint. The older types of austenitic-ferritic duplex steels containing 0.1–0.2% carbon were also unsatisfactory in terms of todays demands on the toughness and corrosion resistance of weldments, mainly because of their high susceptibility to intergranular corrosion (IC).FOR 发表于 2025-3-26 16:14:56

Welding Metallurgy of Austenitic-Ferritic Dissimilar Joints,often a final tempering or stress relieving heat treatment. Austenitic steels on the other hand should be welded “cold”, the welds should cool rapidly and post weld heat treatments should be avoided wherever possible.
