Without stainless alloys based on nickel is difficult to imagine modern industry. Thanks to the durability, wear resistance, corrosion resistance, HN77TYUR alloy, as well as other nickel alloys are in demand in many industrial sectors. Alloy steels are today the main products of the companies involved in metal rolling. Such steels have certain characteristics that they receive during manufacture. In order to obtain the desired properties of the steel produced by engineers selection and calculation of the optimal number of specialty additives used according to the manufacturing technology. After performing the required actions to add to the melt necessary components obtained alloy steel, the main feature of which is superior to mechanical and technological characteristics. Currently, due to the expansion of the production plan for consumers it offers a wide selection of different versions with steel alloying additions.
The percentage of HN77TYUR:
|70 to 77.4||19−22||2.4−2.8||06−1,0||1||0.6||0.4||0.07||0.02||0,015||0.01||0.01||0,007|
Alloy HN77TYUR refers to stainless steel based on nickel and chromium. Nickel alloy as the base material element provides the necessary ductility and toughness. This simplifies the processing of the alloy HN77TYUR pressure. Heat-resistant chromium alloy gives HN77TYUR chemical and corrosion resistance due to the formation on the surface of a solid protective oxide film. Invisible to the eye, it is not only excellent protection against corrosion of steel HN77TYUR, but also has the ability to recover, it is not afraid of accidental damage and scratches. A titanium additive makes the alloy particularly strong.
Key quality at t ° 20 ° C
- yield strength — 620 MPa .;
- Tensile strength — 950 MPa;
- Elongation at Break — maximum 20%;
- limit restriction — no more than 15%;
- Brinell hardness (after hardening) — up to 320 MPa.
HN77TYUR quenching is carried out at t ° 1080 — 1120 ° C with cooling in air or water. Aging is performed at t ° from 700 to 750 ° C for 6−16 hours depending on the type of steel. This alloy is difficult to be welded.
Mechanical properties at 100 ° t ° C
- density — 8.18 g / cm³;
- heat capacity — 13.9 W / (m · deg) $
- coefficient of linear expansion — 12.67 1 / Grad;
- the electrical resistance of 1.247 ohm mm 2 / m
|t °||E 10 — 5||a June 10||Heat capacity||Density|

From alloy HN77TYUR produce discs, rings, blades for turbine gas boilers and similar equipment for work in difficult conditions at t ° up to 750 ° C. For the automotive industry, aircraft construction made important parts increased strength. This gear, piston pins, friction discs, rings, screws in turbines. The alloy is used for parts of furnaces operating at t ° to 1000 ° C in air and the hydrocarbon atmospheres. HN77TYUR Alloy highly hygienic, approaching in this respect to the glass, ideal for measuring and surgical instruments. From it produce parts which have high resistance to aggressive environments and can operate in solutions of nitric acid and sulfuric acid. Flat products are widely used in construction and home: it is made of beautiful decorations, make a branded cookware, frying surface of the boards.
