Technical characteristics

Steel 30CH13 is stainless steel heat resistant alloy of the martensitic class. Used in the manufacture of lightly parts that work at temperatures up to 450 °C. it includes chromium, 12−14% Nickel — 0.6%, manganese and silicon, 0.8%, copper -0.3 percent titanium and 0.2% carbon — 0,26−0,35%, a few thousandths of a percent of sulfur and phosphorus, balance iron. The density of 7.76 g/cm3. 30X13 steel heat-resistant and corrosion-resistant, not prone to temper brittleness, poorly welded and, as a rule, does not apply to welded structures. Pipe of this brand has excellent resistance to atmospheric and soil moisture.

Technological parameters

Pipe production is regulated by the following GOST: 30 245−2003, 10 706−76, 10 705−80, 380−94, 13 663−86, 1050−88, 8639−82, 8642−68, 8645−68. Each of the standards specifies the individual characteristics of the product, for example, tubes with a certain cross section. The temperature of the hot rolling is initially 1180 °C, and at the end — of about 900 °C. When rapid heating and cooling pipes are prone to cracking, so heating step is applied, and slow cooling furnace or sand. For softening heat treatment after hot rolling is used, the annealing at t° 800 °C with cooling at 30 — 50°C/hour. The quenching temperature of about 1000 °C with cooling in air or in oil.

Supplied in tubes of different length. 4−12 m — dimensional length, the dimensional tube length, the length of which is estimated in the range of dimensional. For each cut made allowance for 5 mm, the longitudinal deflection of pipes shall not exceed 10 mm the entire length.

Pipe on the accuracy of production can be high and normal precision. Pipes are of the following types: profile with a square section, with square and rectangular cross-sections.


Details of steam generators, compressors, pumps, cracking plants. Bearings, carburetor needle rods reciprocating compressors, and other parts working at slightly aggressive media up to a temperature of 450 °C. This steel is widely used in petroleum, chemical industry, medical and food industry and in shipbuilding.
