Sheet, strip 18KHG - 16MnCr5 - 16hg
Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a sheet, a strip, which are made of steel grade 18HG (16MnCr5, 16hg). The supplier guarantees the timely delivery of products to any address specified by the consumer.
Low-carbon steel grade 18ХГ (the nearest foreign analogues — steel 16MnСr5, 16hg) is a structural steel alloyed with chromium and silicon. Abroad is also produced according to the AISI 1.7131 standard. It is well amenable to chemical-thermal treatment, as a result of which it significantly increases the surface hardness and wear resistance in the sliding nodes. The presence of chromium increases the heat resistance of the material, but the combined effect of chromium, manganese and silicon limits plasticity at room temperatures. Has good resistance to operation in non-aggressive environments.
Urgency of application
Due to increased wear resistance, 18ХГ steel (16MnСr5, 16hg) is used in the manufacture of piston bolts, rods, camshafts, oil distillers, levers and other similar products in the automotive, pipeline and general engineering industries.
According to the technical requirements of the standard GOST 4543−91, the following elements are included in steel 18ХГ steel (numerical data — in percentage):
|0.15 — 0.21||0.17 — 0.37||0.9 — 1.2||up to 0,3||up to 0.035||up to 0.035||0.9 — 1.2||up to 0.3|
