Zero Heat-Treatment Distortion (35 HRC)<\/p>\n

Because 718H steel is pre-hardened at the steel mill, no post-machining quench heat treatment is needed. This eliminates thermal stress distortion across large core plates, guaranteeing true-to-CAD dimensions on large appliance molds during \u062a\u0635\u0646\u064a\u0639 \u0627\u0644\u0642\u0648\u0627\u0644\u0628 \u0627\u0644\u0645\u062e\u0635\u0635\u0629<\/strong><\/a>.<\/p>\n<\/div>\n

Deep-Section Uniform Hardness (Nickel Addition)<\/p>\n

Unlike standard P20, 1% nickel addition in 718H prevents core softening in massive steel blocks. Jucheng\u2019s 5-axis CNC machining centers cut deep cavity walls with uniform tool wear and \u00b10.005 mm accuracy.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
