Processing of stainless steel structural parts Time:【2020-08-20】 Read together【341】Second 【Printing】 【Return
As we all know, titanium will not corrode. Construction enterprises generally use titanium nails in knowledge, which will not rust and lead to structural collapse. Custom made stainless steel structures are custom-made for machining, and when screws made of other metals are used, they lose strength and stability in harsh weather conditions. Additional repair of common screw damage is an expensive business, so titanium is recommended. Their reliability means that these screws are suitable for important building projects, especially for external structures。

自The definition of corrosion resistance of stainless steel structural parts can directly determine the service life of products made of this material, especially those exposed to the outside. The service life of titanium alloy screw depends not only on its wear but also on its corrosion resistance. In order to improve the corrosion resistance of titanium alloy screw, oxidation method, electroplating method, plasma spraying method, ion nitriding method, ion implantation method and laser treatment method were used to improve the protective effect of titanium oxide film。In order to meet the needs of sulfuric acid, hydrochloric acid, methylamine solution, high temperature wet chlorine and high temperature chloride, a series of corrosion-resistant titanium alloys, such as titanium molybdenum, titanium palladium, titanium molybdenum nickel, were developed in titanium alloy screw for the production of sulfuric acid, hydrochloric acid, methylamine solution, high temperature wet chlorine and high temperature chlorides。

According to the traditional strength design method, for plastic materials, the allowable stress is σ YS / N, and the safety factor n can be 1.1 ~ 2 or more in different situations according to the yield strength. For brittle materials, the allowable stress is σ B ≤ n, and the safety factor n is generally 6。

According to the traditional strength design method, high yield strength of materials will inevitably lead to one-sided pursuit. However, with the increase of yield strength, the brittle fracture strength of materials will decrease and the risk of brittle fracture will increase。

The yield strength of customized stainless steel structural parts is not only of direct significance, but also a general measurement of some mechanical and technological properties of materials in engineering。
