12H15G9ND - 1.4372 - aisi 201 pipe, wire, round

12H15G9ND

This Chrome Manganese stainless steel c low content of nickel. Its structure contains 14−16,5% Cr and up to 0.14% carbon. The alloy is doped with manganese 8.5−10.5%, copper 2%, 1−1.5% nickel, 0.75% silicon, in thousandths of sulfur and phosphorus. Balance is iron.

High-grade stainless 12H15G9ND has a low nickel content, which makes it more resistant to sulfur-containing environments. This steel is recommended as a material for manufacturing a wide profile, operating in slightly aggressive media and under the open sky.

The percentage of

Treatment

Metal easily amenable to forging and planting. Details are cooled in air. The metal has a high strength and ductility when processed in cold condition. It withstands the test of bending corresponding to GOST 14 019−2003. When cold worked steel is hardened and deformed like the steel 12X18H10T.

weldability

Apply argon arc welding on semiautomatic wire 08H20N9G7T, 08H21N10G6 submerged AN-48 using welding NII-48g electrodes, GS-1, DS-12. Welded seams are resistant to intergranular corrosion.

properties

High oxidation resistance, plasticity, easy deformation, the ability to deep drawing, good weldability — allow the use of steel in the same equipment as the chromium-nickel austenitic grades. By lowering the temperature is not observed changes in viscosity and plasticity, which is typical when cold brittleness. Absolute biological inertness make it popular in the food industry. As the mechanical properties of the steel — more durable and solid material in comparison with 12X18H10T. scaling temperature 800 ° C. In direct heat discoloration was observed in the range of 550 to 800 ° C.

Corrosion resistance

High resistance in solutions containing hydrogen sulphide at saturation 2.5 g / l, while the corrosion rate of less than 0.0135 mm / year. In wet hydrogen sulfide and ammonia atmosphere corrosion rate of 0.005 mm / year. In aqueous solution of ammonia at t ° 20 ° C corrosion rate of 0.006 mm / year; at 90 ° C — to 0.097 mm / year. In mixtures of aliphatic hydrocarbons at t ° 20−90 ° C the corrosion rate of 0.003 mm / year. Steel resistant in food medium (wine, beer, juice), with steam at a temperature up to 600 ° C; in solutions of 10% nitric acid and sulfuric acid and 40% phosphoric acid at t ° 85 ° C. According to the Central Research Institute of corrosion: corrosion endurance limits of steel in 3% solution of NaCl = 200 MPa, which is higher than the mechanical properties of 12X18H10T.

application

It is used by the food industry for the no-load or lightly loaded parts: metal utensils, household kitchen utensils, trays, knives, vases for fruits, cover countertops; water containers, thermoses, flasks. For household appliances: stoves; drum washing machines, steel furniture (handles, hinged hinges for doors and so on. n.). In the construction of pipes, door and window frames, handrails, trash cans, etc. Transportation: Car accessories: brush holders for cleaning glass, bumpers;. etc.
