Composition control of weld metal is often performed to maximise the volume fraction of acicular ferrite due to the toughness it imparts. During continuous cooling, higher alloy contents or faster cooling generally delay transformation, which will then take place at lower temperatures, below the bainite start temperature, and lead to higher ...
The majority of sewing machine needles are made of various grades of hardened steel coated with either nickel or chromium, though certain specialty needles are coated with titanium nitride on top of chromium. Titanium nitride is a reflective golden-colored ceramic material which reduces abrasion allowing the needle to stay sharper longer and ...
