Dec-2021The principle of hydrogen embrittlement of fasteners
When hydrogen atoms enter steel and other metals, it will exist on the crystallization of the material. When stress is applied to the metal, it will reduce the ductility or load bearing performance of the metal. Hydrogen embrittlement is delayed dama...08
Dec-2021Uses of various stainless steel bolts
Stainless steel plate anchors generally refer to steel bolts that have the ability to resist corrosion by air, water, acid, alkali or other media. Stainless steel plate screws are generally not easy to rust, durable, and can be used in environmental ...07
Dec-2021Guidelines for choosing stainless steel materials for fasteners
1. Requirements for fastener materials in terms of mechanical function, especially strength.2. The requirements of the working conditions on the anti-corrosion function of the material.3. The requirements of the operating temperature on the heat-resi...06
Dec-2021What are the commonly used stainless steel materials for fasteners
Austenitic stainless steelCommonly used trademarks are 302, 303, 304, 305 four trademarks, the so-called "18-8" type austenitic stainless steel four trademarks. Whether it is corrosion resistance, or its mechanical functions are similar. The starting...05
Dec-2021What are the standard parts disassembly skills
1. Disassemble the rusty bolt and nut standard partsSoak in kerosene for 20-30 minutes. Knock around the nut with a hand hammer to loosen the rust layer, and then unscrew it. If it still cannot be removed, use a torch to heat the nut. When the nut is...04
Dec-2021How to prevent moisture and rust from stainless steel bolts
1. Use impregnating varnish that does not contain oxidizing components, such as epoxy urethane or unmodified epoxy-based impregnating varnish, and apply it to the surface of the stud bolt. Use paint that does not contain volatile acids. Use solvent-f...03
Dec-2021Why are stainless steel bolts magnetic
1. After the stainless steel is cold-headed and cold-rolled, its molecular arrangement changes to form micro-magnetism, but this is only a physical property, and the chemical property remains unchanged; generally speaking, the greater the deformation...02
Dec-2021Basic knowledge of surface treatment of standard parts
Generally speaking, high-strength fasteners can be surface treated to achieve certain goals we want to achieve, such as high temperature resistance. Or avoid the corrosion of standard parts.First, electroplating the standard parts. This method is to ...01
Dec-2021What are the related measures for quality control of non-standard parts
1. All non-standard equipment should be manufactured strictly in accordance with the requirements of the drawings and plans.2. Non-standard production units should compile a construction schedule to facilitate the calculation of the construction sche...
