Description
14KHGS steel is used: for the manufacture of welded structures and litosfernyh, valve components; tubes for plants of chemical and petrochemical plants with nominal pressure PN=19.6−98 MPa (200−1000 kgf/cm2); pipes for pipes in installations for the production of ammonia with a working pressure of PN=31 MPa (320 kgf/cm2).
Note
Steel low alloy bromocinnamaldehyde. The degree of deoxidation — SP.
Steel 14KHGS provides strength grade sheet, universal broadband rental and roll-formed profiles KP 345 with plate thickness of up to 10 mm. without the use of additional hardening treatment.

According to GOST 19282-73, it is allowed to modify steel with calcium and rare-earth elements from the calculation of the introduction of not more than 0.02% calcium and 0.05% rare-earth elements into the metal.
According to GOST 19281-89 and GOST 19282-73, it is allowed to add aluminum and titanium from the calculation of the mass fraction in the rolled aluminum - no more than 0.050%, titanium - no more than 0.030%.
According to GOST 5520-79, the mass fraction of arsenic can be up to 0.15% in the smelting of steel from the Kerch ore, while the mass fraction of phosphorus should not be more than 0.030%. At the request of the consumer, the mass fraction of sulfur should not exceed 0.025, 0.030 or 0.035%, and phosphorus 0.030 or 0.035%. When steel is smelted in electric furnaces, the mass fraction of nitrogen must be ≤ 0.012%.
