Carbon Steel Casting
Low-carbon steels (below 0.15% carbon) contain too little carbon to benefit from hardening and are frequently used in the hot-worked or—for maximum ductility—the annealed condition. Steels of less than 0.25% carbon (often referred to as mild steel) have somewhat higher strength near the upper carbon level.
Medium-carbon steels (0.25–0.55% carbon) are often heat-treated (quenched and tempered) to achieve yet higher strength, but it is mainly the compositions below 0.35% carbon that are relevant to this report. Carbon steel is one of the most widely used materials in the industry. This material is used not only in many of the water- and steam-pressure containing systems in power plants but also in the supports for these systems. Although this report concentrates primarily on the pressure containing applications of carbon steels, it can also be a useful tool for structural carbon steel fabrication issues.
As the description implies, the primary alloying element of these iron based materials is carbon. Because carbon is such a powerful alloying element in steel, there are significant differences in the strength, hardness, and ductility achievable with relatively small variations in the levels of carbon in the composition. However, other important factors—such as material fabrication, heat treatment, component fabrication, and Introduction 1-2 fabrication processes—can result in significant changes to the properties of the carbon steel components.
In some cases, requirements established by codes and standards must be supplemented to achieve adequate results when working with carbon steels. It is important for the utility engineer to have access to metallurgical and properties information to aid in making decisions for projects involving carbon steels. This report is intended to provide such information on the most common boiler and piping materials used in power plants. Not all carbon steels will be covered explicitly, but the user should be able to draw relevant information needed for any required decision.
