High-strength TY-5E bolts are reliable because they are professional

High-strength bolts
We use the most advanced technology, the most advanced materials, and the most top technical personnel to produce high-strength bolts
The meaning of bolt performance grades is divided into three grades for steel structure connection bolts, among which Bolts made of low-carbon alloy steel or medium-carbon steel and heat-treated (quenched and tempered) are generally called high-strength bolts, and the others are called ordinary bolts. The bolt performance grade label consists of two parts of numbers, which represent the nominal resistance of the bolt material. Tensile strength value and yield-strength ratio. For example
The meaning of bolts of performance level is
, the nominal tensile strength of bolt material reaches level
, and the yield-strength ratio of bolt material is
, The nominal yield strength of the bolt material reaches
performance level. After heat treatment, the material of high-strength bolts can reach
, The nominal tensile strength of the bolt material reaches level
, The yield-strength ratio of the bolt material For
, the nominal yield strength of the bolt material reaches
The meaning of bolt performance grade is an internationally accepted standard. Bolts with the same performance grade, regardless of the difference in material and origin, have the same performance. In terms of design Just select the performance level.
The so-called sum of strength levels refers to the shear stress resistance level of the bolt.
It is called tensile strength/nominal yield strength/
Generally speaking, bolts use ,
*The tensile strength of this bolt,
**The yield strength of this bolt
(Because the yield strength/tensile strength/ is specified according to the logo)
Such as
Then the
tensile strength of this bolt is
and the yield strength is */[]

The reason why our company has achieved today’s outstanding achievements is that we strictly follow the coal mine policies emphasized at the beginning of the year The important theory of safety production must ensure that every machine that can enter the coal mine at every step of construction must be safe and efficient, improve every coal miner's familiarity with the machine, and avoid unnecessary injuries. We insist on this and must achieve it. customer's request. Satisfy the needs of customers and do our best to improve customer benefits. At the same time, we can also establish credibility in this highly competitive industry so that we can get greater improvements in the next step. Only by impressing the hearts of customers can we have the motivation to produce. Produce the best product. All suppliers and leaders are welcome to come for observation and guidance.
