Alloy brand ХН40МДБ-VI used in the manufacture of welded chemical equipment operating in solutions of hydrochloric, phosphoric, sulfuric acids, acetic and holodnokatanyh acids. This alloy is produced equipment necessary for the synthesis of acetic acid from methanol oxide and carbon, ion exchange resins, polypropylene, chemical pharmaceutical preparations and other products of organic synthesis. Such tubes can used in low and high pressure pipelines to supply oil and gas industrial petrochemical; high-pressure systems in the nuclear and thermal energy.

Alloy brand ХН40МДБ-VI is a high alloy high-temperature steel. Produced in accordance with the following: 14−1-2131−77; 14−1-2149−77; 14−1-2121−77. The composition of the alloy contains Nickel is 39−42%, chromium 20−22%, therefore it can be called a chromium-Nickel alloy. As additives used silicon, phosphorus, manganese, niobium, copper, sulfur. Smelted in vacuum induction furnaces. The temperature of the steel initially forging is 1170 °C, and at the end — about 850 °C. the Finished product (pipes) with a cross section not greater than 350 mm is cooled in air. Steel pipe brand ХН40МДБ-VI mainly produce round cross-section, along with oval, rectangular and square.
Pipe ХН40МДБ-VI classified according to diameter and wall thickness. When the diameter of 5−250 mm and the wall thickness of 0,3−6 mm, particularly thin-walled pipe called. Thin-walled have a diameter of 5−250 mm and a wall thickness of 0,6−20 mm. Thick-walled pipes have a diameter of from 6 to 250 mm, a wall thickness of 1,6 — 24 mm. Especially thick-walled pipes are made with diameters from 6 mm up to 70 mm wall thickness from 2 to 12 mm.
Rental having a diameter less than 9 mm, are sold in coils and above 9 mm it is delivered straight length: off-gage, measuring, as well as multiple dimensional. High-alloy quality steel ХН40МДБ-VI allows to produce the standard length 1 — 6 m Production length of 2 — 6 m made of low-alloy and carbon steel of standard quality. Alloy quality carbon steel products are made of any parameters.
