Features of welding stainless steel 12h18n10t

Are you interested in the welding technology of 12Х18Н10Т stainless steel from the company supplier АвекГлоб? Here you will find the necessary information on this topic.

Features

Austenitic chromium-nickel steel grade 12H18N10T is well welded by any technologies used for non-removable connections of stainless steels. Like other types of stainless steels, the steel in question is resistant to corrosion and oxidation due to the presence of chromium, and forms a thin protective film on the surface. Steel also has very good viscosity at extremely low temperatures, and is therefore widely used in cryogenic applications. This steel can not increase its strength and hardness as a result of heat treatment, but it hardens well with cold plastic deformation.

The main problem in the welding of 12Kh18N10T steel is the prevention of hot cracking under operational loads, as well as the preservation of corrosion resistance in the zone of formation of the welded seam.

Supplier — AvekGlob company — offers to purchase assortment of welded constructions made of stainless steel 12Х18Н10Т. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.

Prevent distortion and cracks

Since the steel under consideration is subject to a greater thermal expansion than other materials, the welded parts can be distorted easily. Thermal expansion on 12Х18Н10Т steel is more localized than on other similar materials. When the weld is cooled, the slow transfer of heat to the surrounding material results in buckling.

The solution to this problem is to create such a connection that limits the number of necessary welding passes, and together with it reduces the amount of heat. One way to limit these passages is to create a joint structure consisting of a V-groove, a U-groove or a J-groove.

Another way to prevent distortion is to clamp the workpiece. This is especially important for sheet material, since such parts are more prone to buckling.

Distortions are eliminated by using pads of the same material that can be used in automatic or manual welding processes. They provide a zone for «starting» or «lowering» the weld seam by eliminating the starting and stopping of the arc on the actual welded joint. They also help in fully filling the crater area to help prevent cracking and are easily removed after welding.
