What is SS304 Stainless Steel?
Austenitic stainless steel SS304 is renowned for its outstanding corrosion resistance and exceptional durability. The McCoy Power Series Friction Stay hinges are manufactured using this grade of stainless steel. Understanding the chemical composition and mechanical properties of SS304 helps explain its benefits for window hardware applications.
Chemical Composition of SS304:
Chromium: ≥ 17.5
Nickel: ≥ 11%
Carbon: < 0.08%
Manganese: 2%
Silicon: 1%
Phosphorous: 0.045%
Sulfur: 0.03%
Mechanical Properties of SS304:
Hardness: Up to 360 BHN
Fatigue Strength: Up to 440 MPa
Tensile Strength: 1180 MPa
Shear Strength: 690 MPa
SS304’s properties make it ideal for products that require high strength and durability, especially for outdoor applications that face exposure to harsh elements.
Features of McCoy Power Series Heavy-Duty Friction Stay
These friction stays integrate advanced technologies and innovations, setting them apart from standard window hinges.

2. Composite Stainless Steel and Plastic Slider
The combination of plastic and stainless steel in the slider ensures smooth movement with minimal friction, reducing wear and tear while providing self-cleaning properties.
3. Friction Adjustment Mechanism
The friction adjustment screw allows users to easily modify the force required to open or close the window, making operation effortless even for larger, heavier windows.
4. Mechanical Properties of SS304 Stainless Steel
The SS304 stainless steel offers extraordinary mechanical characteristics, such as a tensile strength of 1180 MPa and a shear strength of 690 MPa, making it highly resistant to stress and pressure.
5. Fatigue Resistance
With a high fatigue strength of 440 MPa, the SS304 friction stay can endure multiple cycles of loading and unloading, ensuring long-lasting performance.
6. Built to Last: Corrosion Resistance
The McCoy Power Series Friction Stay is ideal for coastal or industrial environments due to its exceptional corrosion resistance. The SS304 stainless steel undergoes 500 hours of neutral salt spray testing and has a Pitting Resistance Equivalent Number (PREN) of 20, making it highly resistant to rust and corrosion.
7. Self-Balancing and Safety Features
The McCoy Power Series Friction Stay includes a self-balancing sash mechanism that prevents the window from closing unintentionally. This feature enhances safety by ensuring the window stays open when desired.
