HN45MVTYUBR-going alloy tube, circle
Steel brand HN45MVTYUBR-id is one of the most popular on the market of stainless steel. It is widely used by modern industry. The most sought-after product — the tube that is capable of withstanding t ° to 1000 ° C in high-temperature plants. Carefully selected elements in its composition help to improve the chemical and physical characteristics. The basis of an alloy of nickel and chromium, is clearly the effect of chromium on the properties of the alloy are shown at a content of not less than 15%. According to the requirements of GOST Steel this brand contains chromium in the range 15−23% ,. More than 24 percent chromium content in the alloy ceases to «do good work», decreases alloy workability. Steel in its composition provides 45% of nickel and the additive alloying elements.
In its composition Steel grade HN45MVTYUBR-id it contains in addition to chromium and nickel and carbon, sulfur, phosphorus, copper, titanium, aluminum, niobium, cerium, etc. The doping necessary to improve the technological characteristics of products:. Heat resistance and heat resistance, ability to withstand aggressive media. Excessive doping increases the price of the alloy, so it needs to carry out economically: the metal must be manufacturable and operational performance required to meet specific standards. Heat-resistant and heat-resistant steel HN45MVTYUBR-id is the epitome of an optimal balance of price and quality.
Steel-id HN45MVTYUBR smelted in an open arc furnace. Pipe is rolled at the initial t ° 1180 ° C and 900 ° C — at the completion of processing. After deformation, the steel is cooled. According to the first mode there is a cooling air, water or oil, and in the second mode the cooling water goes through a further delay product for about 4−5 hours. Welding is carried out with the help of electrodes type of CT-19.
Circle made hot rolled way diameter 5−270 mm, but most manufacturers go beyond the standard if requested by the customer. The terms of strength can be: high, standard and enhanced durability. Roundness circle can not be higher than 50% of the boundary slope in a circular diameter.
