Oxygen content is an important parameter to measure the level of titanium-zirconium-molybdenum alloy (TZM) products and it is also an important indicator on products’ processing plastic and vacuum performance. But the specific request parameter to determine by the level of the industry average.
American Standard ASTM B387 mark 364 requires oxygen content of TZM not more than 0.030%. But Chinese products due to different sintering production methods lead to different levels of oxygen content which can divided intoⅠandⅡtwo kinds of levels. LevelⅠproduct ‘s oxygen content requirement not more than 0.030%, and the products are usually produce by high-temperature vacuum sintering. Besides using this method the product processing plastic is better, and during vacuum there has small volume decentralized, suitable for forming a variety of high-temperature structural parts, electronic components and other functional parts. Level Ⅱ TZM oxygen content is usually at 0.030% to 0.080%, typically use hydrogen sintering protection to produce, but after processing its room temperature ductility low which is suitable for making a high-temperature structures on non-oxidizing atmosphere conditions.
