Technical characteristics

Brand 07KH16N6-sh (ЭП288-W) refers to a chromium-Nickel alloy austenitic-ferritic class. Widely used in mechanical engineering. The most popular product of it is a tube that can withstand in high-temperature temperature greater than 1000 °C. 07KH16N6 Mark-III is considered to be high-alloy. Carefully selected components contribute to improving the physical and chemical stability. This steel contains chromium in the amount of up to 17.5%. The chromium content in excess of 24% not only increases corrosion resistance, but reduces the manufacturability of the alloy. The composition includes up to 8% of Nickel and additives of silicon, manganese. The purpose of alloying is to improve the technological properties of products: heat resistance and heat resistance, the ability to confront aggressive media. Excessive doping increases the cost of the alloy, therefore, this process is economically: the steel must be manufacturable, and its operational performance should meet the required level.

Steel is smelted in an open arc furnace. Rolling tubes is carried out at a temperature of 1180 °C at the beginning of the process, and 900 °C for its completion. Steel after deformation cooled. In accordance with the first mode is cooled in water, oil or air and the second cooling mode is performed with water, followed by aging products for 4−5 hours. Welded pipe with electrodes CT-19.

The circle is made by hot-rolled method with a diameter from 5 to 270 mm, but the manufacturers in the presence of requirements from the customer expand the boundaries of the standard. Circle release: high, high and standard precision manufacturing.
