High-Carbon Steels - an overview | ScienceDirect Topics

Ramesh Singh, in Applied Welding Engineering (Third Edition), 2020. Welding high-carbon steels. The high-carbon steels contain carbon from 0.60% to 2.00%, and this group of steel is very difficult to weld, as they readily enter the hard and brittle martensite phase, as the steel cools from welding.. The primary use of this type of steel is cutting tools, springs, and abrasion-resistant ...

Corrosion of Embedded Metals - Portland Cement Association

Corrosion of Embedded Metals. Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration inconcrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expansion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling.
