Steel Is The Most Fundamental Material In Fasteners

Apr. 09, 2019

Today Alloy Steel Stamping Fasteners Parts Factory to come to Steel is the most fundamental material in fasteners.

The production of fasteners can be made of steel, non-ferrous metals, stainless steel, titanium alloy, and other engineering materials. The processing method can be hot-processed and machined, but more than 90% of the products are processed by the cold-cold refrigerant. With high precision, good quality and high production obedience, China's fastener industry connection have been linked to a double-digit increase for five consecutive years.

Although the utilization ratio of non-ferrous metals and composite materials is increasing year by year, the effects of steel used for high-strength fasteners cannot be replaced.


All kinds of fasteners are usually constructed from cold rolled steel. In terms of type classification, the steel used for the fasteners is stainless steel, low-temperature alloy steel, aluminum-magnesium alloy, Monel and the like in addition to ordinary carbon steel. Among them, stainless steel and non-ferrous metals account for about 5% of the total consumption of consumables. The steel grades of cold-rolled steel wire rods and wire rods are usually low- and medium-carbon fine carbon layout sheets of steel and low-alloy steels. Low carbon cold heading steel is important for cold heading nuts. The materials used for bolts and screws are mainly medium carbon steel (ML35 and SWRCH35K), which are grade 8 and above after quenching and tempering.


Cold heading is the manipulation of metal plastic forming at normal temperature. The cold heading function is one of the tight junctions of cold heading steel. The performance of the machine is characterized by excellent cold formability; it must have as little resistance as possible and a high deformation ability. Cold heading steel is excellent in cold forming machine, and it is processed by cold drawing instead of hot rolling material cutting machine in the machining industry. The advantage of this kind of process is that while saving a lot of man-hours, the metal loss can be reduced by 10%-30%, suitable for clean production. The capital-saving enterprise has a large production scale, and the product has high dimensional accuracy, good brightness, and good obedience, and is a pioneering machining process. Therefore, the adoption of the cold rolling process to make fasteners is not only subject to high quality, good quality but also saves materials and costs.


Although the development of cold-rolled steel wire rods and wire rods in the sea started late, it has grown rapidly. Especially in the middle of the 20th century, the high-speed wire production line and the wire rod rolling production line have been put into production. The production of wire rods provides the package on the equipment. At the end of 2005, the production capacity of cold-rolled wire rods reached 6 million tons/year (about 1012% of the total wire rod).


The steel mills with Baosteel, Maanshan Iron and Steel, Xinggang, Xiangtan Iron and Steel and Hangzhou Steel, which have established cooperative relations with the fastener industry, have formed the property group of cold wire rods in China. The types of products are low-carbon, ultra-low-carbon, medium-carbon (tempered), low-alloy alloy steel and generalized carburizing and softening steel. The specifications range from 5.5 to 42 sisters, which are used to cover fasteners. All steel is needed.
