State of the sheets, circles, wires, tubes of steel 08Х17Н15М3Т, ЭИ580

Technical characteristics

Grade 08Х17Н15М3Т (ЭИ580) belongs to the type of highly alloyed austenitic steels. It has high resistance to intergranular corrosion of base metal and welded joints in aggressive environments up to 80 °C. It is used in the production of welded equipment for urea and phosphoric acid synthesis columns, as well as in contact with other aggressive media in cases where the use of steel with a lower content of nickel causes focal corrosion in areas of S-ferrite.

Chemical composition (GOST 5632-72)

This steel grade is produced in electric arc furnaces in full compliance with strict requirements of state standard.

Production

The following rolled products are manufactured: rounds, tubes, wires, sheets, strips. Production is regulated by following GOSTs: 18 907-73; 5632-72; 25 054-81; 18 143-72; 5949-75; 7350-77; 4405-75; 9941-81; 9940-81. In stamping, rolling and forging, the initial process temperature is 1170 °C, and at completion it is about 900 °C. Such steel can be machined by cutting, which expands the possibilities of its use.

Physical properties at t° 20°C

- Thermal conductivity 0.147 - 10² W/(m - K)

- Specific weight 7.9 ^g/cm3

- Modulus of elasticity 20.3 - 10 - ^{4 N/mm2}

- Hardness - 200 NV MPa ^-1

- Specific electrical resistance is 0.75 ^Ohmxmm2/m

- Specific heat capacity is 0.504 - 103, J/(kg - K);

- Magnetic permeability 1.255 micro Tesla/m

Welding

It is carried out by automatic, gas-electric, electric arc welding methods. Sheet thicknesses of up to 10 mm can be easily welded by means of electric arc welding. The argon-arc method is recommended for sheets with less than 6 mm thickness and for root welds over 10 mm. In order to prevent hot cracks in welds over 10 mm, root joints should be welded back-to-back using niobium-free welding components. Sheet thicknesses over 12 mm are welded using a combined method (argon arc welding and piece electrode welding). Seams facing the corrosive environment are welded last with OZL-20 electrodes.

Use

Production of welded chemical equipment for the manufacture of urea synthesis columns, and mineral fertilizers. Also used in the manufacture of tanks which are operated in extraction phosphoric acid, 55% acetic acid and other highly aggressive environments at temperatures up to 80 °C. It is used for the manufacture of welding electrodes 08Х17Н15М3Т, which are necessary for connections of fittings, in joints of pipelines, repairs of welded joints of equipment, which operates in a radioactive environment.
