Introduce the prevention of hydrogen embrittlement in spring steel. Spring steel and its alloys produce hydrogen due to comprehensive or local corrosion in pickling solutions. The newly generated hydrogen enters the metal and accumulates at internal defects or stress concentration points, causing fracture. This type of fracture occurs in various spring steels (especially high-strength spring steels) and various stainless spring steels and their alloys. The hydrogen embrittlement caused by acid pickling of spring steel will bring trouble to future processing. To prevent hydrogen embrittlement of spring steel, the following methods can be adopted.
A spring is a mechanical component that works by utilizing elasticity. Generally made of spring steel. Used to control the movement of mechanical components, mitigate impact or vibration, store energy, measure the magnitude of force, etc., widely used in machines and instruments. The types of springs are complex and diverse, classified by shape, mainly including spiral springs, spiral springs, plate springs, etc. But how much knowledge do you have about the use and maintenance of springs
The surface treatment technology of spring Dacromet and chromium free zinc aluminum coating is a new concept of surface treatment developed to meet the VOC regulations and environmental requirements of the automotive industry in various countries around the world. As an updated product of zinc chromium coating (Dacromet), chromium free zinc aluminum coating has been widely recognized and accepted by the automotive manufacturing industry. Currently, there are only a few products that have achieved industrialization of chromium free zinc aluminum coatings: one is the Geomet coating launched by MCI in the United States, and the other is the Delta coating launched by Delta in Germany
How to distinguish the size and length of steel? How do we know the size of the most commonly used steel in our daily lives? We have springs such as small springs, medical springs, antenna springs, etc. They have sizes such as outer diameter, inner diameter, and length, and steel also has its own name. Here are a few points to distinguish the ethnic sizes of steel
