Material Introduction & Manufacturing Process
17-4PH stainless steel is a precipitation-hardened alloy known for its exceptional combination of strength, toughness, and corrosion resistance. Its composition includes chromium, nickel, and copper, providing both mechanical superiority and anti-corrosive properties.
Manufacturing Process:
- Raw material (17-4PH SS) inspection
- Hot forging and precision machining
- Thread rolling with CNC control
- Heat treatment for precipitation hardening
- Surface treatment (passivation or plating)
- Assembly with nuts and washers
- Final inspection and packaging
Typical Applications in Steel Structures
These hex bolts are widely used in industries and structural applications requiring high tensile performance and resistance to harsh environments:
- Steel structures and fabrication
- Bridge construction
- Offshore platforms
- Heavy machinery assemblies
- Wind energy towers
- Mining and infrastructure projects
The combination of high-strength classification (10.9S) and stainless steel resilience makes them ideal for both indoor and outdoor uses, especially in corrosive or high-vibration environments.
