Corrosion resistance

In accordance with the following specifications: 14−1-1154−74, 01/14/69 273 14−1-1541−75, 14−1-240−72, 14−1-2144−77 alloy 03H17N14MZ when tested in boiling 65% nitric acid (density 1.41 g / cm3) made from distilled water and completely pure acid OFS-1 1−3 11 according to GOST 125−73 must be resistant to intercrystalline corrosion. According to the above listed. conditions, in addition to the TU 14−1-2144−77, test duration is 3 cycles of 48 hours each — on quenched samples.

The duration of the test in accordance with TU 14−1-2144−77 of 5 cycles each for 48 hours. The corrosion rate of the alloy should be not more than 0.5 mm / year. This steel 03H17N14MZ according to GOST 5582−75 method of control by GOST 6032−89 should be resistant to intergranular corrosion. According to those. conditions 14−1-1847−76 control of resistance to intergranular corrosion is normalized AMU GOST 6032−89 and is carried out on the samples after quenching. .

application

In the manufacture of urea 03H17N14MZ alloy used for the lining of the synthesis column and mixers, and in the manufacture of caprolactam — cyclohexane oxidation reactors. This alloy is used in the production of welded structures, which are operated in sulphate media, as well as in boiling 10% acetic and phosphoric acids.

Treatment

Plastic hot deformation is carried out in the temperature range of 1150−900 ° C. This steel has high plasticity. Water quenching at 1080 ± 20 ° C is used to relieve work hardening and after cold-hot plastic deformation.

Welding

Good weldability of all types of automatic and manual welding. When an electric hand-welding are used electrodes RLA-20 with steel wire 03H17N14M2 (or EP551). In the process of automatic welding in inert gas or submerged arc wire used the same brand. Strength and corrosion resistance of welded joints while not lower than the base metal. Welds steel urea synthesis in a medium not susceptible to intergranular, corrosion, and the blade have 0,041−0,11 corrosion rate mm / year.
