17-4 PH Stainless Steel Casting Service
When industries demand stainless steel components that combine robust mechanical strength, good corrosion resistance, and the flexibility of precipitation hardening, 17-4 PH stainless steel casting rises to the challenge. Also known as Grade 630, 17-4 PH offers a potent blend of strength and resistance to corrosive environments, making it a popular choice in aerospace, petrochemical, and energy sectors. At Dawang Metals, we specialize in producing high-quality 17-4 PH stainless steel cast parts through our advanced foundry practices. Our commitment to precision and consistency ensures you receive castings that maintain top performance in the most demanding conditions.
Key Properties of 17-4 PH Stainless Steel
17-4 PH (Precipitation Hardening) stainless steel contains approximately 17% chromium and 4% nickel, along with additions of copper and niobium (or columbium). Through a controlled heat treatment process, its mechanical properties and corrosion resistance are enhanced. Notable characteristics include:
High Strength and Hardness: Achieves superior tensile and yield strengths with appropriate aging treatments.
Good Corrosion Resistance: Excels in environments where both strength and anti-corrosion attributes are required.
Precipitation Hardening Capability: Allows for a variety of heat treatment conditions (H900, H1025, etc.) to meet specific mechanical demands.
Stable Performance Across Temperatures: Retains reliable mechanical properties in a broad range of operating climates.
These unique qualities make 17-4 PH an excellent material for structural applications that must support significant loads and resist corrosive damage over long service lives.

17-4 PH Stainless Steel Casting Process
17-4 PH Stainless Steel Investment Casting
We use silica sol investment casting to produce high-precision 17-4 PH stainless steel components with exceptional surface finishes. This method offers tight dimensional control, suited for parts requiring robust strength and corrosion resistance.
17-4 PH Stainless Steel Sand Casting
Our sand casting process employs resin sand and pearl sand, providing uniform grain size and consistent heat resistance. Rigorous testing and recycling procedures ensure that 17-4 PH castings meet stringent quality standards.
17-4 PH Stainless Steel Shell Mold Casting
Our shell mold casting line, equipped with eight automated machines, can handle parts up to 200 kg and deliver a monthly output of 800 tons. This system maintains reliable production of 17-4 PH components without compromising quality or precision.
Post Treatments of 17-4 PH Stainless Steel Casting
Heat Treatment
17-4 PH stainless steel benefits from controlled heat treatment cycles, including normalizing, annealing, and tempering. By carefully managing temperatures and cooling rates, we can enhance this alloy’s hardness, strength, and corrosion resistance.
Post Machining
After casting, we refine each part’s dimensions and surface finish through processes such as grinding and polishing. These finishing steps help 17-4 PH components meet specific industrial or design requirements.
Surface Finishes
We offer rust prevention oil, painting, sandblasting, chemical treatments, anodizing, and polar electrophoresis to protect and enhance 17-4 PH stainless steel parts. These treatments improve durability, corrosion resistance, and overall appearance.
17-4 PH Stainless Steel Casting Products & Applications
Due to its impressive balance of strength and corrosion resistance, 17-4 PH is highly sought after across various fields, including:
Aerospace & Aviation: Turbine blades, structural brackets, and landing gear components subjected to continuous stress and corrosive environments.
Petrochemical & Oil/Gas: Valves, pump shafts, flanges, and fittings operating in corrosive fluids and high-pressure conditions.
Nuclear & Power Generation: Components where strength-to-weight ratio is essential and prolonged exposure to heat or radiation can occur.
Medical & Dental Instruments: Surgical tools and device components needing exceptional cleanliness, strength, and corrosion resistance.
Military & Defense Equipment: Weapon system parts, missile components, and other hardware under elevated mechanical and environmental demands.
By employing 17-4 PH stainless steel castings, industries can enhance longevity, reliability, and cost-effectiveness in systems that face rigorous operational stress.
