The most important factor in BA of AK steels is the control of precipitation of AlN, and composition is the key. It has been found that the optimum nitrogen and soluble aluminum contents are 0.005–0.01 wt.% and 0.025–0.04 wt.%, respectively.A favorable coination of nitrogen and aluminum not only inhibits the recrystallization process by the formation of AlN precipitates, but also results

Sacial Anodes FAQs – Performance Metals

Q. What do sacial anodes do? A. All metals immersed in an electrolyte (sea water for example) produce an electrical voltage. When two dissimilar metals are in contact (electrically connected) they produce a galvanic cell (like a battery), with the less noble metal (a bronze propeller for example) forming the anode and the more noble metal (stainless steel shaft) forming the hode.

Acid mine drainage - Wikipedia

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks
