Thermocouple Materials Discover how different metals in thermocouples create varying voltage levels. Learn about common thermocouple types like K and J, each with unique characteristics. Choose the right one for precise temperature readings. For additional knowledge, check out: https://lnkd.in/dzV6jig5 #Thermocouple

With so many different "types" of thermocouples in the world, how do we know the difference between them?! What makes a "Type C" thermocouple different from a "Type J" thermocouple?! Aside from differences in price, of course, the various thermocouple types are simply made from different combinations of dissimilar metals. Not only that, but you'll notice that a Type D and Type C thermocouple are actually constructed with the same two metals... but they are in different concentrations. So... what makes the various types of thermocouples different?! It all comes down to the type and mixture of dissimilar metals that make up the sensing element. The chart below goes into much more detail, and also explains the benefits and drawbacks of each thermocouple type. Pretty cool, huh?! 😎 #thermocouples #temperature #Nanmac

#Hydrogen causes changes in the mechanical properties and behavior of metal, from the reduction of ductility to increased fatigue behavior to hydrogen-induced cracking. Selecting components made from the right materials – such as austenitic alloys with nickel content between 10% and 30% – can help avoid #embrittlement issues. But what’s the right balance between what you need and what’s available? And how do you decide? We can help you navigate material selection so that you get exactly what you need for your application.

Make sure that your 316 SS has at least 12% nickel content to avoid hydrogen embrittlement. Furthermore, ensuring a nickel equivalency of at least 27 can also provide some assurance that your 316 SS will perform well in hydrogen applications. Nickel equivalency is defined as Ni eq = (12.6 × C + 0.35 × Si + 1.05 × Mn + Ni + 0.65 × Cr + 0.98 × Mo)

Today is New Year's Eve, considered the last day of the year and the most important festival for the Chinese people. Our colleagues at the smelter are still trying to meet a deadline. A new φ680mm Gr5 titanium ingot is out. We are currently using: vacuum consumable arc furnace (VAR), the maximum melting 10 tons, titanium ingot product maximum φ680mm. It is a process that uses arc heat to heat and melt metals. Its working principle is to generate physical and chemical reactions during the formation of droplets and drops at the lower end of the electrode to remove gas impurities and non-metallic inclusions, such as oxides, nitrides, and some harmful impurities with low melting points. This process is carried out in a vacuum state, there is no slag and other materials between the consumable electrode and the spindle, so the material to be smelted is not contaminated. At the same time, when the vacuum arc furnace smelting, the smelted metal is directly exposed to the vacuum, so the degassing effect is very good, can effectively remove hydrogen, nitrogen, oxygen and other gases

There are various methods to purify graphite. On the WFI US side of things, we’ve only had experience with high-temperature methods. Aside from our own experience, there are different methods like flotation, alkaline acid, chlorination roasting, etc… This goes back to our posts, over the last few weeks. There are so many material-specific techniques to fabricate high-purity graphite parts, that we’ve found there is no shame in leaning on experts. We’ve even found that part fabricators may not know every detail behind purifying graphite parts. High-temperature vacuum induction purification furnace at Advanced Carbon Technologies:

Hydrogen mobility and transportation applications have unique operational demands. Only the highest grades of #StainlessSteel can resist the introduction and diffusion of hydrogen molecules into the material. Lesser-quality stainless steels with low nickel and chromium content are more susceptible to on-road corrosion and #hydrogen embrittlement. Learn about how our 316 stainless steel is specifically formulated to overcome #HydrogenEmbrittlement with enhanced strength and corrosion resistance. https://bit.ly/43Wj9qU

Flux is an integral component in the removal of metallic oxides that would otherwise inhibit filler metal flow. It is a chemical compound applied to the joint surfaces before brazing. Understanding the functions of flux and the stages of flux during heat application will help you achieve strong joints in your manufacturing process. The four functions of flux: • Protect from oxygen • Dissolve & absorb oxides • Help filler flow • Indicate temperature Stages of flux during the brazing process: • 212°F/100°C - water boils off • 600°F/315°C - white & puffy • 800°F/425°C - cloudy appearance • 1100°F/593°C - clear & active Visit our YouTube channel here to learn more about the functions and stages of flux : https://hubs.li/Q02BlzZJ0 #lucasmilhaupt #steelpartners #alloy #flux #technicalexpertise #engineering #bestinclass #manufacturer #verticalintegration #innovation #fabrication #joinwiththebest
