Characteristics of 10-brand steel
10 steel is a high-grade structural carbon steel used in ductile components and structures used in temperatures of -40°С to +450°С. Hot-rolled and forged long products made from 10 steel conform to the DSTU 7809 and GOST 1050 standards.
Classification: High-grade structural carbon steel.
Product: Rolled products, including shaped.

Application
10 steel is widely used due to its low cost and high usability. It is found in flat products for cold-forging; components requiring high ductility and preservation of characteristics at temperatures up to +450°С; components that have been thermo-chemically treated with high surface hardness and durability (bushings, screws etc); arc-welded pipes for tubular electric heaters and certain mechanical devices; seamless cold-sized tubes for boilers; oil and steam heaters; the main layer in hot-rolled dual-layer corrosion-resistant sheets; and hydraulic pipes for automobiles, combine harvesters, tractors, fridges, etc.
Welding
10 steel possesses excellent characteristics for manual-arc, automatic-arc, and spot welding. However, these methods are not appropriate for components that have undergone thermo-chemical treatment, as they have very low welding capacity.
