1、 Core features and functional positioning

Made of alloy steel through heat treatment process, with a tensile strength of over 800MPa and no corrosion after salt spray test for more than 500 hours. Mainly suitable for permanent connection scenarios that withstand dynamic loads or are exposed to humid and corrosive environments.

2、 Comparative analysis of performance parameters

Compared to ordinary carbon steel nails, the product has significant advantages in three aspects: 1) yield strength is increased by 2-3 times; 2) Extend the service life by 5-8 years in marine atmospheric environment; 3) The extreme temperature range (-40 ℃ to 150 ℃) maintains stable mechanical properties.

3、 Typical Industry Application Examples

1. Ship engineering: used for riveting of decks and bulkheads, certified according to ISO 2048 standard;

2. Bridge construction: applied to the connection of steel box girder segments, meeting the requirements of AASHTO specifications;

3. Petrochemical equipment: As a flange fastener for reaction vessels, it has excellent resistance to hydrogen sulfide corrosion.

4、 Selection and usage points

The diameter of the nail rod should be matched according to the thickness of the connecting piece, and special hydraulic tools should be used during installation to ensure that the pre tightening force meets the standard. It is recommended to use sealant in acidic and alkaline environments to enhance the protective effect.
