Hexagon bolts are the most typical high-strength fasteners. Hexagon bolts are made of high-strength steel, or bolts with high preload. Hexagon bolts are mainly used to connect bridges, railways, high-voltage and ultra-high-voltage equipment. The bolt is broken and brittle. In order to ensure the sealing performance of the container, it is necessary to prestress the hexagonal bolts used in the ultra-high pressure equipment. Heavy Hex Bolt Wholesaler introduced the effect of heat treatment on hexagonal bolts:

Hexagon bolts must be quenched according to relevant technical requirements. Quenching heat treatment is to improve the mechanical properties of fasteners, so as to meet the requirements of tensile strength greater than a predetermined value and product qualification rate.

The heat treatment process has an important influence on the internal quality of high-strength fasteners. Therefore, in order to produce high-quality, high-strength fasteners, heat treatment technology and equipment are necessary. Due to the mass production, low price, fine thread, and precise structure of hexagon bolts, heat treatment equipment must have a large production capacity and a high degree of automation.

The heat treatment quality is good. The cleaning, heating, quenching, cleaning, tempering, decoloring and coloring of high-strength fasteners are automatically controlled, which effectively guarantees the quality of heat treatment. Threaded fasteners can cause decarburization. When they do not meet the mechanical performance requirements, they will trip first, causing the threaded fasteners to fail and shorten their service life. Because the raw material is decarburized, if the annealing is not proper, the decarburized layer of the raw material will deepen. In the heat treatment and tempering heat treatment process, some oxidizing gas is usually introduced from outside the furnace.
