The Research Institute of Steel has not participated in the Army exhibition for 3 years, naturally, therefore, during these three years it managed to develop and bring a number of new developments to prototypes or series. Firstly, the line of personal armor protection equipment was completely updated. At the Army, the Institute showed new modular Sarmat armor sets, a series of new Elbrus-T and K26 armor helmets, a new protective folder and a shatterproof blanket.
The new protective structure of the helmet using a high-strength economically alloyed titanium alloy made it possible to create one of the lightest helmets in the Br2 class. So a helmet with a protection area of 14 sq.dm weighs only 2.1 kg. The closest competitors barely fit in 2.2 kg with an area of less than 13 sq.dm.
The Research Institute of Steel managed to achieve good results in the development of armored panels, especially the Br4 and Br5 levels.

So three years have not been in vain.

Samples showing the scientific capabilities of the institute turned out to be interesting for visitors. One of such samples is the supermotor panel BMD–1, BMP-1/2, made of high-strength aluminum ACM alloy, which the Research Institute of Steel developed 50 years ago and which has been produced all these years, passed acceptance and suddenly began to break through.

The reason is a violation of the heat treatment technology developed by the Research Institute of Steel and instead of natural aging, which was prescribed by the technology, the duration of which was 90 days, the manufacturers decided to apply accelerated artificial aging technology (24 hours at 100 ° C). The result is a loss of plasticity of the alloy and substandard plate damage. A novelty was also the demonstration of the principle of operation of spaced steel barriers. Why, with an equal total thickness, do some break through, while others do not? For professionals, this is no longer a question, but ordinary visitors discovered something new for themselves.

As always, new materials and protective structures aroused interest. Here, as a novelty, the Research Institute of Steel presented the structure "titanium-steel", where an economically alloyed titanium alloy VST-2 with a ceramic-like front layer is used in the front layer, which is being developed by VSMPO Avisma together with the Research Institute of Steel. The presented structure gives a gain in weight of more than 20% in comparison with standard steel armor of the same level of protection.
The new anti-mine chair of the Research Institute of Steel also shows for the first time. It differs from previous models with better ergonomic performance and an improved system for damping shock dynamic overloads.

As serial products of the Research Institute of Steel presented at the exhibition ceramic armor panels for military equipment, elements of dynamic protection, SAMZ, lattice screens, RPM "Cape", steel 44S-SV-Sh.

By the way, many samples of serial products of the Research Institute of Steel could be seen at the stands of other companies.
Here are the DZ containers on the tower - designed and manufactured at the Steel Research Institute
Lattice screens on the BTR-82AT developed by the Research Institute of Steel
The lattice screens on the BMP-2M are also designed and manufactured at the Research Institute of Steel
Separately, it is worth dwelling on the serial products that the Research Institute of Steel has been producing for many years, but I took them out to exhibitions – these are polymer balls for linear devices. At the Army 2020, this product was shown for the first time and aroused great interest. Attract the unique characteristics of this product. Having better resistance to dynamic loads than traditional steel balls, polymer balls do not require lubrication, are not afraid of dirt, aggressive environments, are almost twice as light as steel, etc.

In general, the results of the exhibition for JSC "Research Institute of Steel" give an optimistic forecast for both the near and far future. Many Russian developers of military equipment and weapons and many foreign companies are also interested in the products of the Institute. It remains to bring this interest to real contracts and start preparing for the next exhibition "Army-2021".
