17-4PH H1150 Stainless Steel: Ultra-High Strength & Corrosion Resistance for Industrial Applications
Solve your high-stress, corrosion-prone component challenges with 17-4PH H1150. Precision-engineered for aerospace, medical, and industrial applications where strength, durability, and machinability are non-negotiable.
Trusted by Fortune 500 manufacturers for molds, shafts, and structural parts—delivered with China’s fastest lead times and ISO 9001-certified quality.
Core Pain Points in Sourcing 17-4PH H1150
Corporate purchasing managers and technical directors face six critical challenges when sourcing 17-4PH H1150 stainless steel:
- High Costs from Western Suppliers: European and US suppliers charge 20-40% premiums for 17-4PH H1150, inflating project budgets without proportional quality gains. Data: 2025 Metal Pricing Index shows Asian suppliers offer 17-4PH H1150 at $8-$12/kg vs. $15-$20/kg from Western mills.
- Inconsistent Heat Treatment: H1150 condition requires precise aging at 1150°F (621°C) for 4 hours. Poorly controlled processes lead to reduced toughness (Charpy impact < 50 ft-lb vs. target 80 ft-lb).
- Long Lead Times: Overseas suppliers quote 12-16 weeks for custom sizes, delaying production schedules.
- Surface Defects: Improper machining causes work hardening, leading to micro-cracks in high-stress applications (e.g., turbine blades).
- Certification Gaps: Lack of NADCAP or AS9100 approvals blocks aerospace/defense contracts.
- Minimum Order Quantities (MOQs): Mills demand 5+ metric tons, forcing excess inventory costs for prototypes.
Result: Projects stall, budgets overrun, and quality risks multiply—unless you partner with a supplier like Guangdong Yingtai.

FAQ: Your 17-4PH H1150 Questions Answered
Q: What’s the difference between 17-4PH H1150 and H900?
H1150 is aged at 1150°F (621°C) for 4 hours, offering higher toughness (80+ ft-lb Charpy) but slightly lower strength (1100–1300 MPa) than H900 (aged at 900°F, 1300–1500 MPa, but only 20–40 ft-lb toughness). Choose H1150 for impact-resistant applications like aerospace fasteners; H900 for static high-strength parts like mold bases.
Q: Can you supply 17-4PH H1150 in custom shapes?
Yes. Our 5-axis CNC machining and EDM wire cutting handle tolerances down to ±0.01mm. Common custom forms:
- Rounds: Ø6mm–Ø500mm
- Plates: 5mm–200mm thick
- Hex bars: 8mm–150mm AF
- Forged blocks: Up to 1000kg
Q: How does 17-4PH H1150 compare to 316L stainless steel?
| Property | 17-4PH H1150 | 316L |
