HN35VTYU alloy tube, circle
Steel brand HN35VTYU (EI787) is a heat-resistant high-alloy steel, of which the parts are manufactured, designed to operate at temperatures up to 900−1000 ° C in a weakly laden condition. This steel belongs to partially welded, welding is performed while heating to t ° 100−120 ° C followed by heat treatment. In the composition of about 3.1 14 nickel — 16% chromium. In addition — tungsten, titanium, aluminum, one percent of silicon, a quarter percent copper, one hundredth part of phosphorus and manganese.

This steel belongs to the ferritic-austenitic. Compared with austenitic type steels, they have higher strength (almost double), and high resistance to intergranular corrosion type, as well as greater resistance to stress corrosion cracking in chloride and an alkaline medium. The use of ferritic and austenitic steels are directly dependent on the operating conditions. The first long able to withstand temperatures of about 600 ° C. They can be classified as heat-resistant steels. If the output reaches a temperature above 600 ° C, austenitic stainless steels are used. In accordance with GOST intensive education in the air scale begins to occur at temperatures of about 1050 ° C. Pipe HN35VTYU contain slightly less nickel than others. Semi-finished products of the same steel, resulting in increased material fortress and increases its resistance to sulfur-rich environment. HN35VTYU brand tubes can be changed on the other, with a reduced amount of carbon without losing strength advantages. This steel has a balanced characteristics with respect to heat resistance and heat resistance, so it is so popular.
The use of reliable and durable stainless steel pipes save time and money for maintenance and replacement of equipment. For example, no need for color tubes or protective coating applied. The pipe can be made seamless method — Extruded type, and moreover a method of welding — electric welding pipe. In accordance with the type of poerhnosti pipe may be indicated in catalogs as a matte, polished, mirror-polished. Circle HN35VTYU can be used as forgings, ie. E. The intermediate preform for a variety of products. Making a circle of steel of the brand is carried out with the help of metal stamping — strain under a predetermined shape.
