Features of welding nitrided steels
The welding technology of such steels is similar to the welding of stainless steels, as well as ordinary low-carbon steels. Special processing of the edges is not required, and for welding in industrial conditions, suture roller machines are used. However, after the welding itself, an additional operation of smoothing the welding seam is introduced. It is performed on a special ironing machine and allows after surface finishing to apply to the surface wear-resistant, corrosion-resistant and decorative coatings.
Sleek and roller machines reduce the bulging of sheet material, which is typical for most compounds. The pitch of the rollers is set constant, which ensures the uniformity of the pressure and the length of the width of the welded joint that is constant over the length.
Company Electrovek-steel offers to purchase at economically favorable prices from the manufacturer of rolled metal structural nitrided steels. The supplier guarantees the timely delivery of products to any point specified by the customer.
Subsequent processing of welded joints
Since the nitriding process takes place at temperatures not less than 500… 550 0 С, during welding, spontaneous release of the metal located in the weld zone is possible. The exception is nitrided steels that are doped with vanadium: this element reduces the sensitivity of steel to temper brittleness even if the tempering temperature exceeds 650 ° C.
For improved steels, the zone of thermal influence, especially in gas welding, is quite large, which increases ductility and toughness. At the same time, in the weld zone, the past nitrided steel is distinguished by a fine-grained structure favorable for maintaining the durability of the welded structure.
Welding is carried out using special electrodes, which contain molybdenum, as well as in argon, using non-melting tungsten electrodes.
Buy nitrided alloyed structural steel in a wide range of brands and assortment offers the company Elektrovek-steel. Products are sold at the manufacturer’s price. The supplier guarantees timely delivery of metal products to the address specified by the customer.
