Developed with Cr-Mo-V medium carbon steel through precision alloy design1, this casing
series undergoes "normalization + quenching + high-temperature tempering" heat treatment to achieve optimal
strength-toughness balance (HRC≤22). The manufacturing process incorporates
continuous casting with vacuum degassing and electromagnetic stirring for ultra-low impurity content (S≤0.005%, P≤0.025%).
