Composition

Alloy brand 15Х12Н2МВФАБ-sh (ЕП517-W)) is one of the most common in the metal market. This steel has a foreign counterpart. Brand 15Х12Н2МВФАБ-h refers to high alloy high-temperature alloys, is composed of ~12% chromium. It provides excellent resistance to oxidation. In addition to chromium in the composition of approximately 2% Nickel additive 1% of molybdenum, tungsten, niobium and vanadium, as well as hundredths of a percent carbon (015%), phosphorus and sulfur. Since the theory of alloying of heat-resistant steels is based on the effects of various substances on the basis of chromium and Nickel, such steel is called chrome-Nickel alloy. Steel 15Х12Н2МВФАБ-DV provides for its composition of carbon in a limited quantity. Increased carbon content exceeding 0.2% deteriorates the heat resistance due to the formation of chromium carbides.

Percentage composition

Use

The most popular product is a tube, can withstand temperatures of over 1000 degrees in high temperature installations. 12% chromium in the composition guarantees high resistance to the oxidation process. Circles and tubes brand 15Х12Н2МВФАБ-DV demanded in various industries like blanks for the manufacture of parts of movable parts and work fixtures.

Production

Brand 15Х12Н2МВФАБ-sh is smelted into the open arc furnaces. Rusk products with a starting temperature of about 1180 degrees and 900 degrees at the end of the treatment process. After deformation of the product is usually cooled in air. It is also possible cooling in water or oil, followed by aging products. The ovality of the circle should not exceed 50% of the amount of extreme variations in Pipe diameter differ in the ratio of wall thickness to diameter. At a thickness of about 0.3−6 mm and Ø 5−250 mm pipe referred to as extremely thin-walled. Thin-walled tube has a thickness of 0,6−20 mm with the same diameter. Thick-walled pipe has a wall thickness of 1,6−24 mm and Ø 6−250 mm. Particularly thick-walled pipe is made with a wall thickness of 2−12 mm, Ø 6−70 mm. Welding can be performed with one kind of electrodes CT-19.
