A516 GR.70 Spectacle Blind

The performance of spectacle blinds produced by chromium element is better than that of general spectacle blinds, mainly because of chromium element. Generally, spectacle blinds made of stainless steel are added with chromium element, which is because chromium is often used in chemical industry to make stainless steel. In addition, in our production of spectacle blinds, chromium plating on metal can prevent rust, also known as multi meter, solid and beautiful. The spectacle blind produced in this way will have better performance than the ordinary nickel base alloy spectacle blind. In general, chromium based alloys are relatively brittle, and their use as metal materials is still under study. Chromium is mainly used to produce stainless steel and various alloy steels in the form of ferroalloys (such as ferrochromium). However, our spectacle blind flange will undergo heat treatment in the production. Metal chromium is used as an additive for aluminum alloy, cobalt alloy, titanium alloy, superalloy, resistance heating alloy, etc. Chromium oxide is used as a light and heat-resistant coating, as well as an abrasive, a colorant for glass and ceramics, and a catalyst for chemical synthesis. Basic chromium sulfate (trivalent chromium salt) is used as tanning agent for leather. Chrome alum and dichromate are used as mordants, impregnants and various pigments for fabric dyeing. Chromium plating and chromizing can make steel, copper, aluminum and other metals form a corrosion-resistant surface, which is bright and beautiful, and is widely used in construction and other industries. In addition, chrome ore is also widely used to make refractory materials. Therefore, our spectacle blinds made of this material will be visually brighter than ordinary stainless steel spectacle blinds. Of course, its price will be slightly higher, but for customers who have this performance demand, they will still use products made of this material.
