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.

Metal is easy to planting and crafting. Ready-prepared foods are cooled on the 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.
The main advantages
High oxidation resistance, plasticity, easy deformation, the ability to deep drawing, good weldability allow to use the alloy as well as austenitic chrome-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 starts above t° 800 °C. the color of the tint occurs during 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 (t° 20°C) to 0.006 mm/year; (90°C) — to 0,097 mm/year;
— in a mixture of aliphatic hydrocarbons (temperature 20−90°C) up to 0,003 mm/year;
Steel is used in industrial chemistry. She stand in contact with solutions of 10% sulfuric acid and nitric acid, and phosphoric acid (40%) to t° 85 °C and water vapour at t° to 600 °C. Suitable for the unloaded or slightly loaded parts in the food industry (production of beer, wine, juice), for kitchen household utensils, metal utensils, knives, trays, coatings of cutting tables, food containers, jars and Termoli. Household appliances: cookers; steel fittings, drums of washing machines.
