ASTM A217 stainless steel castings in the product form of valves, flanges, fittings and other pressure-containing parts. ASTM A217/A217M covers one grade of martensitic stainless steel and nine grades of ferritic alloy steel which are primarily utilized in high-temperature and corrosive service. It includes C-Mo alloy steel: Grade WC1; Cr-Mo alloy steel: Grade WC4, WC5, astm a516 grade 70 temperature range, Grade WC6, WC9, WC11, C5, C12; Cr-Mo-V alloy steel: Grade C12A; and Chromium Steel: Grade CA15.

The main difference between astm a516 grade 70 temperature range, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest astm a516 grade 70 temperature range processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain astm a516 grade 70 temperature range by rolling method.
