DIC Fasteners is an Exporter of all kinds of industrial nuts in various countries. These industrial are available with us in various sizes, shapes, styles, grades, and plating.
High-class stainless steel nuts are mainly imitated in their technical requirements, and thickened nuts are commonly used.
A high-strength stainless steel nut, made of high-strength steel, or a nut that requires a comparably ample torque to lock can be called a high-strength nut. Many high-strength nuts or high-pressure and ultra-high-pressure equipment are used to fasten flyovers and rails.
Is the high-class stainless steel nuts safe for equipment?
The crack mode of High-class steel nuts is a generally brittle crack. Usually, to ensure the sealing of the container, we require large pre-tensioning when installing the high-pressure equipment.
Using high-strength steel nuts these days, most power generation equipment and vehicles such as airplanes, cars, trains, and ships are undergoing rapid development.
Therefore, locking elements such as our nuts also need to follow the trend and develop quickly to keep up with the development momentum.
High-strength nuts are mainly used to fasten critical mechanical equipment, particularly the repeated disassembly and assembly, and various assembly techniques have high requirements for nuts.
The surface finishes of High strength steel nuts
The surface position and accuracy of the thread will affect the use of the equipment and the safety factor. Usually, to adjust the amount of friction and avoid rust and jamming during use, we require that the surface be plated with a layer of nickel and phosphorus.
The high-strength nut nickel-phosphorus plating process consists of three parts.
First is the pre-plating treatment, which mainly comprises the precision and presence examination of the high-strength nut before plating to see whether there are fissures or defects, and the oil mark can be manually removed, or It can be removed by engagement, or pickling, followed by electricity to operate the nut and rapid nickel plating;
Then the electroless nickel plating procedure and a sequence of chemical methods to plate nickel on the nut;
Last is the Post-treatment procedure; post-treatment generally comprises procedures such as removing the heat caused by hydrogen, polishing treatment, and finished product inspection.
Should focus on some prominent points of the high-strength nut
High-strength steel nuts need to pay attention to some problems. First, the standard needs to pay attention to the surface cleaning needs to be thorough, and then the friction amount must meet the technical requirements,
The use of high-strength stainless steel nut standard high-strength nuts has been widely used and generally comprised of two strength levels, Grade 8 nuts, and Grade 10 nuts, of which class 10 is the majority.
High-strength nuts are more practical than ordinary nuts. With the advancement of technology and life, the execution of high-strength nuts has gradually become more widely used. Now its execution and status in the industry are irreplaceable.
