GOSTs for steel 12Х15Г9НД

Production

Nickel-depleted grade 12Х15Г9НД contains: chromium 14-16,5% and carbon 0,12%. Alloying is made by copper 2%, manganese 8.5-10.5%, which to a certain extent becomes a substitute for nickel, 1-1.5% Ni, silicon 0.75%. Sulfur and phosphorus are contained in thousandths of a percent. The base of the alloy is iron.

Percentage composition of 12X15G9ND (GOST 5632-72)

Processing

The metal can easily be shaped and forged. The finished semi-finished parts are cooled in the air. Cold forming is also possible, since the metal not only has high strength, but also cold ductility. In the process of cold working, the steel is deformed and hardened similarly to the 12X18H10T grade. Welding: argon arc semi-automatic welding with wire 08Х20Н9Г7Т, electrodes GS-1, NII-48G, DS-12; 08Х21Н10Г6; under fluxes AN-48. Welded seams are resistant to intergranular corrosion.

The main advantages

High resistance to oxidation, ductility, easy deformation, the possibility of deep drawing, good weldability allow the alloy to use as widely as the austenitic chromium-nickel grades. The loss of ductility and toughness characteristic of cold brittleness is not observed when the temperature decreases. Biological inertness makes the steel popular in food processing. In terms of its mechanical properties it is a stronger and harder material compared to 12X18H10T grade. The oxidation begins above t° 800 °C. The annealing color is observed during direct heating in the t° range from 550 to 800 °C.

Corrosion rate

- Up to 0.005 mm/year in a wet ammonia and hydrogen sulphide atmosphere;

- in a solution containing hydrogen sulfide at a saturation level of 2.5 g/l less than 0.0135 mm/year;

- in an aqueous solution of ammonia (t° 20°C) up to 0.006 mm/year; (t° 90°C) up to 0.097 mm/year

- in a mixture of aliphatic hydrocarbons (t° 20-90°C) to 0.003 mm/year;

Use

Steel is used in industrial chemistry. It is resistant in contact with solutions of 10% sulfuric and nitric acids and phosphoric acid (40%) to t ° 85 ° C, and in water vapor t ° to 600 ° C. Suitable for unloaded or lightly loaded parts in the food industry (beer, wine, juice production), for kitchen appliances, metal utensils, knives, trays, coating of cutting tables, food containers, flasks and thermos. In white goods: stoves; steel fittings, washing machine drums.
