Corrosion Resistant Nickel Chromium Molybdenum Alloy

Alloy 625 is a nickel – chromium – molybdenum alloy containing niobium, iron and tanatalum to improve its corrosion resistance and mechanical properties. Alloy 625 is a solid solution-strengthened alloy that retains a large amount of its mechanical strength through a range of temperatures from cryogenic values up to elevated temperatures. It also provides high corrosion resistance in a wide range of media and is used in power generation, chemical process industries, offshore sour oil and gas production, waste incineration, phosphoric acid production, nuclear fuel processing, high temperature environments and aerospace. The annealed state of Grade 1 material alloy 625 as stocked by Columbia Metals provides an excellent combination of hardness, corrosion resistance, yield, fatigue and tensile strength at high temperatures up to 815°C. It also features high resistance to oxidation and scaling up to 980°C under cyclic heating conditions. The use of Alloy 625 is restricted to a maximum temperature of 595°C for long term exposure. Alloy 625 has excellent properties for resisting corrosion erosion and corrosion fatigue in a wide variety of media including freshwater, seawa...

Hands-On: The HYT H3, With Linear Fluid Time Display

In the cluttered modern luxury watch landscape, it never hurts to have something that clearly sets you apart from the competition, and HYT pretty much has the fluid horology niche all to itself. The company’s signature design element is its liquid time display, which when it debuted in 2012 got pretty much everyone’s attention. The idea of using liquids to display the time is of course, absurd from a practical standpoint, but far more relevantly for modern high end horology – much of which is involved in actively exploring new technologies and materials as performance advantages, and to offer new creative opportunities – it looked, and looks, very cool, and HYT since then has not only succeeded with its highly idiosyncratic first designs, but also continued to expand its visual and technical languages. In 2015 HYT introduced what was at the time its largest and most complex watch: the H3. Previous HYT models (and for that matter, all subsequent HYT models as well) implement the fluid time display with a circular tube, and a bellows system feeding colored fluid into one end of the tube, and clear fluid into the other. The meniscus between the two fluids marks the poin...
