Our company leverages unique forging equipment, adjusts element content, and strengthens process control. During steel melting, we strictly control the contents of S, P, H, O, and limit harmful elements such as Pb, Sn, Bi as required by customers. We adopt bottom pouring for ingot casting and optimize the shrinkage ratio of large ingots to ensure steel purity and compactness, reducing nonmetallic inclusions. Inclusion testing is conducted in accordance with GB/T10561-2005, and the rating of A, B, C, D types shall be ≤2.0 (judged by the worst case).
