The group of ingot casting shall be determined by the main alloy elements. The specific requirements shall comply with the stipulation in Table 1 below. 4.1.3 The second and third digits in the nameplate is the sequence number of ingot casting. It is adopted to identify different ingot castings in the same group. 4.1.4 The English letter in front of the decimal point and the digit behind the decimal point are type identification code. They are adopted to identify different types of the same ingot castings whose chemical composition is approximately the same. 4.2 Chemical Composition 4.2.1 The chemical composition of ingot casting shall comply with the stipulation in Table 2. 4.2.2 In Table 2, if the content has an upper and lower limit, it is alloy element; if the content is a single numerical value, it is the highest limit; “---” refers to unstipulated specific value; 4.2.3 Ingot castings for the food and hygiene industry shall control. ; ingot castings for the electrical and electronic equipment industry shall control. 4.3 Mechanical Properties under Room Temperature Tensile When the demand side has certain requirements towards the mechanical properties of ingot castings under room temperature tensile, the content shall be negotiated and determined by the demand side and the supply side and indicated in the order sheet (or contract). 4.5 Fracture Organization The fracture organization of ingot castings shall be compact; there shall be no slag or slag inclusions. 4.6 Amount of Slag When the demand side has certain requirements towards the amount of slag in ingot castings, the content shall be negotiated and determined by the demand side and the supply side.
