Avoid the oxidation of the welded parts in stainless steel
The recommendation is use a pickling gel (or pickling paste) and let it work for a while to remove the oxides and the contamination aggravated during the process f welding, doing immediately a nice wash with water. This way, the oxidation problems will be avoided [...]

Difference between 300 series and 400 series stainless steelÂ
The 300 series are the austenitic stainless steel, which are non-magnetic. The 400 series are the ferritic stainless steel, which are magnetic. The stainless steel from 400 series can be divided in two groups: the ferritic properly, which generally has a higher chrome and a lower carbon; [...]

Properties and corrosion resistence of Alloy 400
Alloy 400 (UNS N04400) is a ductile nickel-copper alloy with resistance to a variety of corrosive conditions. The alloy is most frequently specified in environments ranging from mildly oxidizing through neutral and in moderately reducing conditions. An additional application area of the material is in marine environments and other [...]

Is there any change of stainless steel’s mechanical properties in high temperature ?
The carbon steel and the stainless steel both suffer a reduction in the values of their mechanical proprieties while working in high temperatures.
As a matter of fact, this is an attribute of metals and metallic alloys in general. In common steel, the loss [...]
