High-quality steel is superior to high-quality steel in some or all of the following:
A, reduce the content range of ingredients;
B. Reduce the content of harmful elements (such as sulfur, phosphorus, copper);
C, to ensure a higher degree of purity (requires less non-metallic inclusions);
D, to ensure higher mechanical properties and process performance.
A. Nominal dimension: It is the nominal dimension specified in the standard. It is the ideal size that the user and the production company hope to obtain. It is also the order size specified in the contract.
B. Actual size: It is the actual size obtained in the production process, and this size is often larger or smaller than the nominal size. This phenomenon that is larger or smaller than the nominal size is called deviation.
