alloy steel In addition to iron and carbon, other alloy elements are added to the steel, which is called alloy steel. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements to an ordinary carbon steel. According to the different added elements, and adopt appropriate processing technology, can obtain high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other special properties.

Monel is also called nickel alloy. It is an alloy based on metallic nickel and adding other elements such as copper, iron, and manganese. Has many excellent characteristics.

Inconel alloys are generally known for their resistance to oxidation and their ability to maintain their structural integrity in high temperature atmospheres. There are several Inconel alloys that are used in applications that require a material that does not easily succumb to caustic corrosion, corrosion caused by high purity water, and stress-corrosion cracking. While each variation of Inconel has unique traits that make it effective in different circumstances, the majority of the alloys are used frequently in the chemical industry.  Inconel 601 is a nickel-chromium alloy that has additions of aluminum. These additions increase its resistance to oxidation and various forms of corrosion. This has made Inconel 601 a common material in heat treating equipment, furnaces, and gas-turbine components. Inconel 690 has a similar makeup to 601, but it is considered a high chromium-nickel alloy. The high chromium content in 690 makes it especially resistant to corrosion that occurs from salts, oxidizing acids, and other elements commonly found in aqueous environments.  Inconel 625 differs from many of the other Inconel alloys because its composition includes substantial amounts of nickel, chromium, and molybdenum. It also has an addition of niobium. The result is an alloy that possesses high levels of strength without ever having to go through a strengthening heat treatment. Inconel 625 is especially effective at resisting crevice corrosion, making it a chosen material in the aerospace and marine engineering industries.

Hastelloy C-276 alloy is a tungsten-containing nickel-chromium-molybdenum alloy with extremely low silicon-carbon content and is considered to be a universal corrosion-resistant alloy.

"Stainless steel fasteners" is a specific term concept covering a wide range of products. Stainless steel fasteners are often used for fastening of more expensive machine parts because of their beauty, durability, and strong corrosion resistance. With the progress of society, higher requirements have been put forward for stainless steel standard parts.

No matter what kind of industry, as long as it is assembly, it is basically inseparable from the thread, and the thread is essential for tapping. When it comes to tapping, my friends, you may know more or less. Because it is common for broken taps to appear during processing. Therefore, Xiaobian here is to provide some insights for the master of the fitter, machine tapping, the removal method of broken taps, for your reference.

In the machinery manufacturing industry, a large number of bolt parts need to be applied. Bolt parts are divided into corresponding 10 grades according to their basic properties and performance. Among them, bolt parts with a performance level greater than 8.8 are called high. Strength bolts. High-strength bolts have higher strength and surface hardness, and can be widely used in metal smelting and machinery manufacturing industries. We should fully study the material selection and processing technology of high-strength bolts to ensure that high-strength bolts can meet the requirements of related industries. Demand, so as to enable products in various industries to carry out effective quality assurance, improve product safety and practicability, and then improve the economic and social benefits of related industries.

Fastener is the most common type of standard parts in mechanical products due to its variety, specification, large usage and wide application. The reasonable selection of fasteners has also become an important link in the process of product design. Whether the fasteners are used correctly or not is directly related to the functional realization and safe operation of the product. Compared with general fasteners, high-strength fasteners have different requirements in product design, manufacturing, assembly, inspection and maintenance, and play a more critical role in the operation of equipment. With the development of mechanical products to large-scale, automatic, intelligent and other diversified situations, the use of high-strength fasteners as key functional parts is increasing, especially in key occasions and important parts. At present, there are still some problems in the selection and use of high-strength fasteners, such as different opinions and insufficient understanding. It is necessary to do further research work. This paper mainly discusses the use methods of high-strength fasteners for mechanical products, and does not discuss the use of high-strength fasteners instead of general fasteners.
