Relevance
Rods circle of steel wire 15H25T produce a very long time, since the days of the USSR. These products have excellent corrosion resistance to the atmospheric and soil moisture, when in contact with most acids and alkalis. This tech heat-resistant material is widely used in various industries to welded structures, do not suffer from shock loads when t ° ≤1100 ° C.
Composition
Steel ferritic class 15H25T (EI439) is an alloy of stainless steel complexly. The composition according to GOST 5632 — - — - 72 24−27% chromium, up to 1% silicon, 0.8% manganese, 0.5−0.9% titanium, 0.15 carbon, thousandths of a percent phosphorus and sulfur. Smelted steel in electric furnaces open.

The σ — limit of short-term strength;
σ T — yield limit for residual deformation.
d 5 — elongation at break.The steel semi-finished products readily undergoes hot deformation t ° in the range 1000 — 700 ° C and cold deformation at t ° 150 — 200 ° C. To weld manual arc welding with preheating and final heat treatment. Wire and rods can be either round or square section.
application
Rods circle 15H25T alloy wires have excellent corrosion resistance, heat-resistant and ductile. They are reliable in environments oxidative character in corrosive environments, neutral alkali salts in seawater, for used in the production of caustic soda and like system components for the production of salt. They are resistant to static loads, are used for welded structures that are not subject to vibration and shock, operated at t ° from -20 ° C to 1100 ° C. This — the details of heat exchangers working in hostile environments, furnace fittings, electrodes spark incendiary spark, they are in demand in industrial chemistry, textile, shipbuilding, petroleum and food industry, in the production of medicines as elements of architectural designs. They are also used for the application of a variety of protective coatings.
