But if the demonstration turns into anarchist action, the police will definitely take enforcement action, because this country cannot lose to the mob, nor can this country lose to intolerant behavior. At the same time, the various trade union organizations that rejected the comprehensive employment law wil...

  The chemical heat treatment of Duplex 2507 stainless steel Chemical heat treatment of Duplex 2507 is mainly the formation of active atoms: the active atoms are absorbed by the metal surface and the active atoms diffuse into the metal. Duplex 2507 flange in heat treatment The speed of these three processes is not only related to the carburizing agent used, but also closely related to the temperature and time during chemical heat treatment. The effect of heating temperature: The decomposition rate of carburizing agent is closely related to the heating temperature. Generally speaking, when the heating temperature is higher, the decomposition rate of the carburizing agent is faster, and the more active atoms are formed. Therefore, all chemical heat treatments are mostly carried out in a higher temperature range. However, because there are many types of 2507 stainless steel chemical heat treatment, many of them are carried out at lower temperatures, such as low-temper...

       There are many grades of stainless steel, 300 series stainless steel is the most famous and commonly used, especially 304, 316, etc.. 301 : Good ductility, used for molded products. It can also be quickly hardened by mechanical processing and has good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel. 301 stainless steel exhibits obvious work hardening during deformation, and is used in various occasions requiring higher strength 302 : In essence, it is a variant of 304 stainless steel with higher carbon content, which can be made to obtain higher strength through cold rolling. 302B : is a kind of stainless steel with high silicon content, which has high resistance to high temperature oxidation. 303 and 303Se  are free-cutting stainless steels containing sulfur and selenium respectively, which are used in occasions where free cutting and high surface gloss are required. 303Se stainless steel is also used to make par...
