High-strength bolts are manufactured from high-strength materials.
Screws and nuts for high-strength bolts
and gaskets are made of high-strength steel
Production, commonly used 45 steel, 40 boron steel,
20 manganese titanium boron steel. Q235 is commonly used for ordinary bolts
Steel manufacturing.
High-strength bolts are mainly divided into 2 categories. A class
of carbon steel high-strength bolts. Another type
of stainless steel high-strength bolts. Carbon
steel high-strength bolts mainly include 8.8 grades,
10.9 grades, 12.9 grades, etc. The commonly
used grades of stainless steel high-strength bolts are 80 and 100. Such as
A4-80, A4-100, C3-80, C1-110, A5-80, etc.
Bentley has industry-leading stainless steel resource
integration capabilities, and rich raw material reserves,
to ensure that thousands of leading position in the
stainless steel wire processing industry. The
combination of production, university and research,
upstream and downstream linkage, and the special
research and development of high-standard specific
materials ensure the need for thousands of professional
materials.
Scope of
application
Because the fasteners with black zinc plating have good corrosion resistance and wear resistance, they are suitable for harsh working environments, such as Marine environments and chemical equipment.In addition, black zinc plated fasteners are also commonly used in occasions requiring higher aesthetics, such as automotive, electronics and other industries.
Quality
Certification
The main performance indicators of hexagon bolts are tensile strength, yield strength, hardness, etc., and the tensile strength of high-strength bolts (grade 12.9) can reach more than 1200MPa. The maximum stress that a bolt can withstand when it is deformed but not completely damaged, and the high-strength bolt has high yield strength and better durability.
inspection
Bentley has invested a huge amount of money to build a product testing laboratory, equipped with imported high-end instruments: such as thread comprehensive scanners, high temperature tensile testing machines, high frequency fatigue testing machines, etc., to ensure that all products are strictly tested before leaving the warehouse to ensure the reliability of customers during use.
