Duplex Stainless Steel Containing Molybdenum Is Used in Xiamen Mountains-to-Sea Trail 244

Carbon steel is widely used around the globe for the construction of bridges of sizes ranging from the very large to the very small, but now many bridges around the world are approaching the end of their useful life because carbon steel bridges do not have the corrosion resistance benefits offered by chromium, molybdenum and other alloying elements. The forward-looking design of the Soderstrom Bridge with duplex stainless steel highlights the benefits of building bridges from structural stainless steel in…

What Are Excellent Properties of Molybdenum Disulfide in High Temperature Grease? 268

Molybdenum disulfide (MoS2) is a naturally occurring black solid compound that is slippery to the touch. It transfers easily and adheres to other solid surfaces it comes in contact with. Its mineral form — called molybdenite — was often confused with graphite until the late 1700s. Both have been used for lubricating and writing materials for centuries. So, what are the excellent properties of MoS2 in high temperature grease? 1)it can improve the bearing capacity of the grease and make…

Why Tungsten Crucibles and Molybdenum Crucibles Are Used for Sapphire Crystal Growth? 272

Crystal growth is the foundation of many cutting-edge technologies such as sapphire touchscreens, LED lighting components, solar cells and high-power lasers. Corrosion resistance, creep resistance and high temperature properties enable tungsten and molybdenum crucibles to be used for high temperature sapphire crystal growth processes. Crucibles made of tungsten and molybdenum materials perform well in the heat exchanger method (HEM) process for melting and solidification of single crystals. Better sapphire yield and quality can be achieved when the sapphire is easy…
