The study presents a comparative analysis of consumer properties of platinit by different producers. Both the products of Russian companies and the foreign counterparts are considered. It was established that the domestic platinit, though not very different in composition from its foreign analogues, is still inferior to them in its parameters, such as physical and technological properties, as well as surface quality.

Modern technology of hardware production occupies an important place in ensuring the fabrication of metal products for various industries. Production of steel rail fastening elements, such as spring-loaded clips, which play a significant role in improving the efficiency and safety of rail transport, is an important application of such technology. These products are characterized by complex shape, high quality requirements, as well as high level of physical, mechanical and performance properties. OJSC "MMK-METIZ" is one of the leading Russian companies producing railway hardware. Currently, to maintain its position in the market of rail fasteners, the company implemented a number of research, development and engineering works in the field of organization of production of bar-shaped spring clips OP-105 and ZhBR. As a result of these works, the required level of quality of the finished products has been achieved, allowing the use of manufactured spring clips on the railways of Russia.

The paper investigates two different protective phosphate compositions for the chemical treatment of water and the use of them with a view to improve quality of “make-up” water in water heating systems. The research proved a positive effect of reducing the corrosive activity of water and the amount of scale.
