Hot-rolled stainless steel circle ST.38Kh2MYuA, 25 mm, refers to a relaxation-resistant heat-resistant material with molybdenum. The main purpose is the manufacture of nitrided parts that can operate at temperatures above 450 degrees. Fingers, rollers, bushings, gears, plungers are made from a circle of hot-rolled 38X2MYUA. All parts are used in aircraft and rocket engines.
Hot-rolled circle 38X2MYUA is manufactured in accordance with GOST 4543-2016. According to this regulatory document, the metal includes aluminum, manganese, silicon, molybdenum, copper, sulfur, nickel, phosphorus, carbon and chromium. The last element is the most important. Its percentage is 1.35-1.65. The metal belongs to difficult-to-weld materials and is not used for this operation. Heat treatment involves quenching and tempering. The first operation is performed at a temperature of 880 degrees, tempering - at 650 degrees. Long products of this brand are very often subjected to nitriding. This operation improves the corrosion-resistant qualities of the metal in any working environment.
Circle 38x2MYuA is a part made of high quality structural steel, which has been displayed in the range of metal profiles due to a number of performance properties.
Features of products from 38x2MYUA
The presented sample of the circle is regulated by the properties of the steel grade, which was chosen as the material for production. This:
Relative lightness (the product is 500-600 kg lighter than chrome-plated counterparts);
Sufficient strength (229 MPa);
Exclusion of use for welded structures;
The goods are offered in the processed form of bars, ready for use for their intended purpose.
The prospect of choice
A circle of steel 38x2MYuA is made from a special steel alloy with a high content of ferum, chromium, manganese, nickel, molybdenum and aluminum. In this case, the product:
Multifunctional;
Stable in its physical and chemical properties;
Resistant to corrosion processes.
This significantly expands the scope of operation.
What is it used for?
The metal-rolling industry of Russia has companies that buy in bulk lots of blanks in the form of circles for the production of:
gears;
bushings;
rollers;
Fingers.
The product retains its physical properties at temperatures up to 450o.
Steel 38Kh2MYUA is used for the manufacture of valve stems for steam turbines operating at temperatures up to +450 °C, cylinder liners for internal combustion engines, nozzle needles, bushing plates, sprayers, pins, plungers, camshafts, gears, shafts, bushings and other parts, parts rocket and aircraft engines, parts of pipelines quenched in oil and tempered in oil or water, nitrided aircraft parts, solid-rolled rings for various purposes.
In the manufacture of parts from steel 38Kh2MYuA, the nitriding process is often used.
Hot-rolled circle - produced in accordance with GOST 2590-2006. Such circles have different levels of accuracy, from normal to high. The areas of application for such circles are diverse, they can be used in cold drawing, as well as in hot mechanical processing.
The circle is calibrated – it is made in accordance with GOST 7417-75. In this case, the heat treatment of steel divides circles into two types - these are cold-rolled and cold-drawn.
Stainless circles - are produced in accordance with GOST 14955-77. Such wheels are immune to corrosion changes and have a coating on the surface. It should be noted the high resistance of stainless steel circles to elevated temperatures.
Due to these properties, circles are widely used in the oil and gas industry. Stainless steel circles are often used as semi-finished products and are used in the construction of platforms, oil and gas pipelines, as auxiliary components in pipe production.
In the form of blanks, the circle is used in the construction of aircraft, in mechanical engineering, in the manufacture of vehicles, in the construction of ships, in almost all types of construction and repair work.
The range of application of circles made of stainless steel in the food industry is quite extensive. Due to their durable and anti-corrosion properties, the wheels have become indispensable in the preparation, handling and storage of all kinds of products. A large use of circles occurs in the production of components for cooking and baking food.
In medicine, the use of stainless steel circles is also common, because they have such properties as environmental friendliness and are absolutely safe in terms of hygiene.
In the recycling process, circles are used in the manufacture of measuring instruments, in the creation of structures and equipment elements. It should be noted that circles are widely used in the construction of various objects. Such circles have a special coating on their surfaces, they can be either matte or polished.
Stainless steel circles can begalvanized and used in an aggressive environment, in the manufacture of parts for electrical wires, for grounding elements. The galvanized circle, due to its coating, is perfectly protected from fires and various kinds of influences, such as the mechanical effects of the environment.
Stainless wheels have different properties, this is influenced by the chemical composition of the steel from which the metal product is made. Different steel grades have a different chemical composition, respectively, and a different content of chemicals, such as C (carbon), Mn (manganese), S (sulfur), Cr (chromium), Ni (nickel), Al (aluminum) and others.
The standard defines the size range, tolerances and other parameters for hot-rolled round steel. The permissible diameter is from 5 to 270 mm. Rolled products are manufactured in three types of accuracy: normal, high and high.
Hot rolled steel is produced by a completely different method. During the molding process, the workpiece is subjected to strong heating and, therefore, the temperature deformations that occur during this are significant. This leads to the fact that the resulting product is less accurate in size, because it is impossible to accurately predict the behavior of steel when it cools. It is for this reason that the hot-rolled circle has a lower cost.
The second important difference from the calibrated one is the surface. Temperature influence leads to the fact that it contains traces of scale and, in addition, it is less light. This is what makes the hot-worked circle less attractive for design purposes.
As far as stiffness is concerned, hot-rolled steel is generally softer than cold-rolled steel. Consider this when buying. This difference is due to technology and may be important to the buyer.
Stainless steel round bars occupies an important position in the industrial production of the country. Most often it is used as a blank for any cylindrical parts. It is widely used in the manufacture of various metal structures (including as a decorative element), parts for valves, tools, machines and equipment.
A distinctive feature of rolled products is their high resistance to oxidation and, in some cases, to highly aggressive environments. For example, steel 12X18H10T works well at temperatures up to +350 degrees in high activity environments. Some steels perform well at very high temperatures. All this makes round stainless steel indispensable in many industries.
Not all grades of stainless steel have the same performance characteristics. Therefore, we recommend that you contact a specialist before purchasing.
The most important features of this product, as a stainless steel circle, are increased resistance to absolutely any technological damage, resistance to metal corrosion manifestations over time, high strength, heat resistance, and ductility. To increase the strength, a stainless steel wheel is subjected to thermal hardening, artificial aging, hot firing in specially designed furnaces and other types of heat treatment. In addition, the level of strength of the final product is largely affected by the degree of the circumference of the section, namely the cross section.
There are products with a dark surface or a lighter one. This indicator depends directly on the manufacturing and processing technology.
