Steel 10KHSND (SKHL-4)
Designation
Description
The 10KHSND steel is used: for the manufacture of welded steel elements and various details and requirements of high strength and corrosion resistance with the restriction of mass and operating at temperatures from -70 to +450 °C; rolled, intended for the manufacture of bridge structures normal Northern execution; load-bearing elements of various welded structures, parts of pipeline valves after quenching and tempering; as a base layer in the manufacture of hot-rolled dual-layer corrosion-resistant sheets.
Note
Chronographically low alloy steel with copper. The degree of deoxidation — SP.
The 10KHSND steel provides strength class long products, strip and shaped rolled KP 390 with a thickness up to 15 mm.
The 10KHSND steel provides strength grade sheet, universal broadband rental and roll-formed profiles KP 390 with plate thickness of up to 40 mm. without the use of additional hardening treatment.
Standards
Chemical composition
Fe is the basis.
According to GOST 17066-94, the mass fraction of arsenic is allowed up to 0.015%, with the mass fraction of phosphorus being not more than 0.030%.
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. In the steel, cobalt is allowed up to 0.050%.
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 6713-91, nitrogen content is allowed up to 0.012%. In steel, deoxidized with aluminum, the residual content of acid-soluble aluminum should be not less than 0.020%. The use of other deoxidizers is allowed. In the rental for bridge structures of the northern version, the mass fraction of sulfur should not exceed 0.030%, phosphorus - not more than 0.025%. Manufacture of electroslag remelting steel is permitted. The analysis of rolling on arsenic and nitrogen is made at the request of the consumer. In the finished rolled category 3, the mass fraction of silicon should be 0.70-1.00%.
According to TU 14-1-5120-2008 the chemical composition is given for high quality steel grade 10ХСНДА. A mass fraction in the finished sheet steel is allowed up to 0.012%.
