SUS630 corresponds to the domestic Chinese grade 05Cr17Ni4Cu4Nb (GB/T 1220-2019), formerly 0Cr17Ni4Cu4Nb (GB/T 1220-2007)....

The hardness of 630 stainless steel (namely 17-4PH, a martensitic precipitation-hardening stainless steel) is directly related to its heat treatment state, with significant hardness differences observed under different conditions: Solution-treated (non-a...

17-4PH is the American grade equivalent of SUS630....

17-4PH is equivalent to the Chinese national standard grade:<0.05Cr17Ni4Cu4Nb (recommended for use in the new standard) or its old grade 0Cr17Ni4Cu4Nb. Its unified numerical code is S51740....

17-4PH is a martensitic precipitation-hardening stainless steel. Its core feature is achieving a balance between high strength and moderate corrosion resistance through solution annealing + aging heat treatment, making it a commonly used high-strength sta...

The Chinese designation corresponding to 17-4PH is 05Cr17Ni4Cu4Nb (according to GB/T 1220-2019 standard)....

The hardness of 17-4PH directly depends on the aging temperature—the lower the aging temperature, the higher the hardness. The typical range is 30–45 HRC. Hardness at Different Aging Temperatures (Typical Process: 4 hours hold + air cooling):...

The yield strength of 17-4PH mainly depends on the aging temperature, ranging from 800–1200 MPa. Lower aging temperatures correspond to higher yield strength. Yield Strength at Different Aging Temperatures (Typical Process: 4 hours hold + air cooli...

The core heat treatment process for 17-4PH is “solution treatment + aging”, which together balances strength and toughness. Different aging temperatures correspond to different mechanical properties. 1. Solution Treatment (Pre-treatment, prep...
