Certified raw material sourcing, certified heat-treatment verification, and extreme tolerance manufacturing calibrated specifically for 17-4 PH Stainless & 4140 Alloy Steel Precision Machining components.
17-4 PH undergoes low-distortion single-step aging from Condition A up to H900 (44 HRC) with negligible dimensional change.
4140 pre-hardened (28-32 HRC) withstands immense shock loads and repetitive torque reversals without shear.
CBN (Cubic Boron Nitride) tool inserts turn hardened surfaces directly, eliminating the need for slow secondary grinding.
Liquid or gas nitriding of 4140 produces surface hardness exceeding 60 HRC with superior anti-scuffing properties.
