Composition

Brand 12Х15Г9НД depleted in Nickel, includes: chrome 14−16,5% carbon 0.12 percent. The doping is made by copper 2%, manganese about 8.5−10.5%, which to a certain extent become a substitute for Nickel, 1−1,5% Ni, silicon of 0.75%. Sulphur and phosphorus are contained in thousandths of a percent. The basis of the alloy is iron.

Treatment

Metal is easy to planting and crafting. The finished parts are cooled in air. Possible stamping and cold, because metal is not only high strength, but plasticity in cold condition. In the process of cold working steel deformed and hardened similarly Marche 12KH18N10T. Welding: argon arc semi-automatic welding with wire 08Х20Н9Г7Т, electrodes GS-1, Sri-48G, DS-12; 08Х21Н10Г6; under flux an-48. The welded seams are resistant to intergranular corrosion.

Basic properties

High oxidation resistance, plasticity, easy deformation, the ability to deep drawing, good weldability allow to use the alloy in the same hardware as the austenitic chromium-Nickel stamps. When temperature reduction is not observed loss of ductility and toughness characteristic of brittleness. Biological inertness makes steel popular in the food industry. According to its mechanical properties it is more durable and solid material in comparison with the brand 12X18H10T. Okalinoobrazovanie occurs at 800 °C. the color of the tint is observed when direct heating in the range of temperature from 550 to 800 °C.

The corrosion rate

— in moist ammonia and hydrogen sulfide atmosphere up to 0.005 mm/year;

in the solution containing hydrogen sulphide at saturation 2.5 g/l less 0,0135 mm/year;

— in an aqueous solution of ammonia at t° 20 °C to 0.006 mm/year; at a temperature of 90 °C — to 0,097 mm/year;

— in a mixture of aliphatic hydrocarbons at a temperature of 20−90°C to 0,003 mm/year;

Use

Steel is used in industrial chemistry. She stand in contact with solutions of 10% sulfuric acid and nitric acid, and phosphoric acid (40%) at t° of 85 °C and in water vapour at t° to 600° C. Suitable for lightly or non-loaded parts in the food industry (production of beer, wine, juice), for kitchen household utensils, metal utensils, knives, trays, coatings, countertops, vases for fruit; for water containers, jars and flasks etc. household appliances: cookers; steel fittings (wall hinges, handles for doors, etc.), drums of washing machines. In the construction industry: pipes, door and window frames, trash cans, handrails, etc. In transport: car accessories: bumpers; holders for brushes for cleaning glasses etc.
