..., hydrogen embrittlement, or both. At subzero temperatures, the steel was below its ductile-to-brittle transition temperature. These circumstances suggest a brittle condition. Steps to avoid this type of failure: For cold conditions, the steel plate should have a low carbon content and a high manganese-to...

... acid slag practice, phosphorus and sulfur could not be removed during the steelmaking process. Low sulfur steel could be produced if a low sulfur pig iron was used, such as that smelted from low sulfur iron ore obtained from Sweden. This was a common source of iron ore used in Britain in the late 19th...

Abstract The interior of a cylindrical tank used for the road transport of concentrated sulfuric acid revealed severe blistering of the plates, mainly over the crown and more particularly on the first ring. The tank, made in 1958, was of welded construction, the material being mild steel plate...
