Hinges

Stainless Steel 316 (SS 316) butt hinges, often referred to as marine-grade hinges, are designed for high-corrosion environments like coastal areas, chemical plants, and food processing facilities. The addition of molybdenum (2-3%) provides superior resistance to chloride-induced pitting compared to standard SS 304.

 

Core Material Specifications

The mechanical and chemical properties of SS 316 ensure it remains non-magnetic and physically durable under heavy loads.

 

• Chemical Composition: 16-18% Chromium, 10-14% Nickel, and 2-3% Molybdenum.

• Tensile Strength: Approximately 515 MPa (75,000 psi).

   

   

• Yield Strength: 205 MPa (30,000 psi).

   

   

• Density: 8.0 g/cm³.

   

   

• Finish: Typically available in Mirror Polished, Satin/Brushed, or Superior Matt.

Common Mechanical Dimensions

Butt hinges are measured by their height (length), open width, and leaf thickness. Standard specifications for residential and industrial use include:

 

 

Size (Height)	Standard Widths	Average Thickness	Typical Use Case
1.5″ (38mm)	1.5″ (38mm)	1.5mm – 4.0mm	Cabinet doors, boat hatches
2″ (50mm)	2″ (50mm)	2.0mm – 4.5mm	Small lockers, marine furniture
3″ (75mm)	2″ – 3″	1.6mm – 2.5mm	Standard internal doors, toolboxes
4″ (100mm)	3″ – 4″	2.5mm – 3.0mm	Main entrance doors, heavy cabinets
5″ (125mm)	3″ – 4″	3.0mm – 4.0mm	Heavy-duty industrial or metal doors
