High-Strength Alloy Steel Structural Nut

This product is a high-strength alloy steel structural nut designed for heavy-duty fastening applications requiring high load-bearing capacity and impact resistance. It is suitable for use in demanding environments such as aerospace, industrial equipment, and structural assemblies.

Key Features

Material: 30CrMnSiA (30ХГСА)
This alloy steel offers high tensile strength and good toughness. After heat treatment, the hardness reaches 29–35.5 HRC, enabling the nut to withstand heavy loads and impact conditions. It provides significantly higher performance compared to standard carbon steel nuts.

Surface Treatment: Ц6хр Zinc-Chromium Coating
The zinc-chromium coating delivers a much higher level of corrosion resistance than conventional galvanizing. It is suitable for harsh environments, including outdoor exposure, corrosive media, marine conditions, and industrial atmospheres, effectively extending service life.

Manufacturing Standard: ОСТ 1 33101 (Upsetting and Heat Treatment)
Produced in accordance with ОСТ 1 33101, with upsetting followed by heat treatment to ensure thread precision and overall structural strength. This process helps prevent thread stripping and fracture during fastening, improving connection reliability.
