- Chemically AISI 1214 is one of the more simple steels. The carbon content, .015 percent, translates to a softer steel that is too soft to be truly heat treated but is easy to machine in quantity. The standard allows for a slightly higher than normal level for phosphorus at .07 percent but requires sulfur impurities to be kept below .03 percent. The steel's 1 percent manganese and .1 percent silicon gives the steel some added toughness despite the low carbon content.
- Because the AISI 1214 is such a soft material, with a hardness of between 142 and 205 HB, it is quite easy to machine. The steel is most often used in industries where it is machined in large quantities and through automated means. 1214 is ideal for this type of machining process since its softness doesn't wear on cutting surfaces.
- AISI 1214 steel can be welded via all common techniques including MIG, TIG and MMAW, though the high manganese content results in weak welds. Because of this, 1214 is not recommended for use in industries where high weld strength is required such as the automotive industry.
- AISI 1214 is sometimes used as a decorative material since it is available in polished form. It can be found in both bar and round form and in many sizes, making it an attractive choice in the manufacture of steel-based products.
