HN28VMAB: alloy tube, circle
Alloy brand HN28VMAB EP126 is a high-heat-resistant steel. In its composition of about 28% nickel and 22% chromium, whereby it can be called chrome-nickel alloy. Furthermore, as additives used to charge up to 0.6% silicon, up to 0.02% phosphorus, and 1.5% manganese, 5 — 6% tungsten, 2.8 — 3.5% molybdenum and about 0.02% sulfur.
The percentage of GOST 5632−72
Temperature semi pull the shoes is initially 1170 ° C and about 850 ° C — at the end. Ready-section pipe to 350 mm is cooled in air. HN28VMAB Steel pipes are usually made with a circular cross-section, but custom made oval, rectangular and square. The scope of use of the pipe divides the product into six main classes. The higher it is, the higher the requirements for heat resistance, heat resistance, corrosion resistance, and therefore, the composition of the alloy, whose strengths are directly dependent on the proportions of the constituent elements.
ClassificationSteel pipes are classified according HN28VMAB wall thickness and diameter. With a thickness of 0.3−6 mm and wall Ø 5−250 mm pipes are the name of a particularly thin-walled. Thin-walled tubes have a wall thickness of 0,6−20 mm and Ø 5−250 mm. Thick-walled tubes have a wall thickness of 1,6−24 mm and Ø 6−250 mm. Pipes thick-walled produce especially with 2−12 mm wall thickness at Ø6−70 mm.
The tubes are thinner than 9 mm, supplied in coils, and more than 9 mm — straight lines that divide the length on the off-gage, cut length and multiple dimensional length. Quality HN28VMAB high alloy steel allows to produce products 1−6 meters. The smaller the carbon contained in the alloy and the lower the quality of the steel, the greater the length of the released product. Rent 2 to 6 meters are made from carbon and low-alloy steel of usual quality. From high-quality alloyed carbon steel manufacture products of any parameters.
first class pipes used for hiding cables in various designs for the manufacture of scaffoldings, when designing the irrigation systems for the local delivery of various fluids, for example, in heating systems and water supply systems. Pipes second class is used in conditions of high and low pressure, therefore they can be used in a pipeline for supplying water, oil, gas and petrochemical various industrial products. Pipes of austenitic-ferritic third class is used in systems with high pressure, so they are often used in the chemical and nuclear industries, different boilers and furnaces, for the manufacture of furnace conveyor boxes for production cementation. Pipes 4 class serve as auxiliary and also as drill pipes with different geological prospecting. By the fifth class include steel pipe, used for the manufacture of automobiles, overhead cranes, towers, in the furniture and woodworking industries. The highest class is the sixth pipe used in mechanical engineering, manufacture of bearings, pistons and other parts operating at elevated pressure.
