Description Steelun of 16ХГ (АЦ16ХГ) Alloy structural steel:

16ХГ (АЦ16ХГ) steel is used: for the production of carburized parts of small sections, working on friction; details of pipeline valves are designed to cut non-aggressive media (water, steam, air, nitrogen, inert gases, fuel oil, oil, oil distillers, diesel fuel, diesel oil, crude oil and petroleum products); parts of front-wheel drive passenger cars by machining.

Note

Steel structural quality chromatorgraphy.
ATS in naming the brand means automatic calcium.
Steel is manufactured with controlled hardenability.
