Technical characteristics

Grade 07Х16Н6-sh (EP288-sh) refers to chromium-nickel alloy of austenitic-ferritic class. It is widely used in mechanical engineering. The most popular product out of it is a tube capable of withstanding a temperature of more than 1000 °C in high-temperature installations. 07Х16Н6-sh grade is considered to be highly alloyed. Carefully selected components help to improve physical and chemical resistance. Such steel contains up to 17.5% chromium. Chromium content of more than 24% not only does not increase corrosion resistance, but also reduces the alloy's processability. The composition contains up to 8% nickel and silicon and manganese additives. The purpose of alloying is to increase the technological properties of products: heat and heat resistance, the ability to withstand aggressive environments. Excessive alloying increases the cost of the alloy, so this process is carried out sparingly: the steel must be technologically advanced and its performance indicators must meet the required level.

The steel is melted in an open arc furnace. The tubes are rolled at 1180 °C at the beginning of the process and 900 °C at the end. The steel is cooled after deformation. The first cooling is done in water, oil or air, while the second cooling is done with water, followed by holding for 4-5 hours. Tubes are welded using electrodes TsT-19.

Round is made by hot-rolled method with diameter from 5 to 270 mm, but manufactures subject to customer's requirements extend the limits of the standard. The circle is produced: high, increased and standard accuracy of manufacturing.
