Most ﬁller metals for duplex stainless steel welding are described as“matching”, but typically they are overalloyed in nickel with respect to the wrought products that they are said to match. Usually there is about2–4% more nickel than in the wrought product
Welding of Austenitic Stainless Steel - TWI
Although commonly referred to as ''stainless steel'', the steels covered in this article should be more correctly referred to as austenitic, 18/8 or chromium-nickel stainless steels. As with the other types of stainless steels, the austenitic stainless steels are corrosion and oxidation resistant due to the presence of chromium that forms a self-healing protective film on the surface of the steel.
Mechanical properties of ferritic stainless steel welds in …
In this study, feasibility of using typical ferritic filler metals (409LNb, 430LNb, and 430Ti) for welding of low and medium chromium ferritic stainless steels (EN 1.4003 and types 409, 430, and 441) was investigated. The paper concentrates on basic mechanical properties of gas metal arc-welded joints at aient temperatures. A variety of mechanical testing, i.e., tension, microhardness
