Sri Sakthi Steels

17-4 PH (UNS S17400) round bars are a precipitation-hardening stainless steel known for their high strength, good corrosion resistance, and excellent mechanical properties. They are a popular choice for applications requiring a combination of these characteristics. Key Properties:

• High Strength: 17-4 PH round bars exhibit high tensile and yield strength, particularly in the hardened condition. 
• Good Corrosion Resistance: Their corrosion resistance is comparable to 304 stainless steel in many environments. 
• Excellent Mechanical Properties: They offer a good balance of strength, hardness, and ductility. 
• Machinability and Weldability: 17-4 PH is relatively easy to machine and weld. 
• Non-magnetic: They are generally non-magnetic, especially in the annealed condition. 
• Precipitation Hardening: This steel is hardened through a precipitation heat treatment, which creates a martensitic crystalline structure. 

Typical Applications:

• Aerospace Industry:Due to their high strength and corrosion resistance, they are used in aircraft parts and components. 
• Petrochemical Industry:Their resistance to corrosion and high strength make them suitable for equipment in this sector. 
• Paper and Pulp Industry:The material's durability and corrosion resistance are valuable in this industry. 
• Other Industries:They are also used in various applications requiring high strength and corrosion resistance, such as in marine environments, and for tools and dies. 

Mechanical Properties (Typical Values in Hardened Condition):

• Tensile Strength: 160-190 ksi (1100-1310 MPa)
• Yield Strength: 130-150 ksi (900-1035 MPa)
• Elongation: 10-15% (dependent on heat treatment)
• Hardness: 38-44 HRC (depending on heat treatment) 

Chemical Composition:

• Chromium: 15.00 - 17.50%
• Nickel: 3.00 - 5.00%
• Copper: 3.00 - 5.00%
• Carbon: 0.07% (max)

Stainless steel 17-4 PH bright round bars are used for mechanical components requiring high strength, hardness, and good corrosion resistance, such as in the aerospace (aircraft structures, engine parts), chemical, food processing, and oil and gas industries. Common applications include pump shafts, valve stems, gears, turbine blades, and mechanical seals.  Key uses and applications

• Aerospace: Components for aircraft structures, accessories, and engine parts. 
• Oil and gas: Pump shafts, oil paths, and components for pipelines and refining equipment. 
• Chemical and power generation: Equipment for chemical processing, power plants, and nuclear reactors. 
• Food processing: Machinery and components for food production. 
• Mechanical components:
  • Valve stems, balls, and seats 
  • Mechanical seals 
  • Springs 
  • Turbine blades 
  • Propeller shafts 
  • Gears and shafts 

Why it is used

• High strength: It can be heat-treated to achieve very high tensile strength and hardness. 
• Corrosion resistance: It offers good resistance to corrosion, particularly in certain environments like marine vessels or when not exposed to air, making it suitable for a wide range of applications. 
• Toughness: It provides a good balance between strength and impact toughness. 
• Weldability: It can be forged, welded, and machined, making it versatile for manufacturing complex parts.
