Relevance

Steel 10Х11Н20Т2Р (ЕИ696А-vd) is a heat-resistant high-alloy grade. It is used for the manufacture of parts operating at a temperature of about 900-1000 degrees Celsius in low-loaded state. This steel is limited weldable, ie, welding of products should be performed after heating to 100-120 ° C followed by heat treatment.

Manufacturing and use

Stainless pipe grade 10Х11Н20Т2Р contains about 11% chromium and 20% nickel, alloyed with 2% titanium, as well as aluminum, silicon, manganese, has a hundredth of a percent phosphorus and sulfur. Such a balanced composition makes it possible to produce power type units.

This steel has high characteristics of heat resistance and heat resistance, which is why it is so popular. Pipes of grade 10Х11Н20Т2Р include a lower content of nickel than products of similar grades, so the strength of the material increases, increasing its resistance in sulfuric environments. Heat-resistant products of 10Х11Н20Т2Р grade can be exchanged for other products with lower carbon content in order to keep their mechanical properties.

Tubes can be made by seamless method - solid drawn, and by welding method - electrically welded. Depending on the type of coating, pipes are distinguished: matt, mirror (polished) or polished.

The manufacture of a circle 10Х11Н20Т2Р is carried out with the help of stamping - modification under the given form. These circles can be used as forgings, i.e. intermediate blanks for a variety of products.

Classification

Grade 10Х11Н20Т2Р belongs to the austenitic-ferritic class. As compared to austenitic steels it has higher reliability and resistance to intergranular corrosion, corrosion cracking in alkaline and chloride media. Ferritic steels can operate at temperatures up to 600 degrees Celsius. They are classified as heat resistant. If it is necessary to withstand temperatures above 600 degrees, then austenitic steels are used. According to GOST, intensive scale formation in the air atmosphere begins at about 1050 degrees Celsius.

Advantages of

The use of stainless steel pipes saves time and money for maintenance and replacement of equipment. One of the most important advantages of stainless steel is also the absence of the need for a special protective coating of pipes.
