That hardware you've photographed is a Milano Soft-Closing Concealed Cabinet Hinge (also known as a European hinge).
Key Features & Details ⚙️
* Brand: Milano (clearly marked on the hinge arm).
* Function: Soft-Closing (it has an integrated mechanism to prevent the cabinet door from slamming).
* Material: The search results suggest it is made from SS 304 Stainless Steel (or Stainless Steel Grade SUS304), which is known for its excellent corrosion resistance and durability. The "SS 304 steel" detail you provided is consistent with premium versions of these hinges.
* Type: The most common design for this type of hinge is a Clip-On or Slide-On Concealed Hinge (also called a cup hinge or Euro hinge), used for cabinet doors.
* Application: These are primarily used for kitchen and wardrobe cabinet doors.
* Mechanism: The parts shown include the main hinge arm (with the soft-close damper) and the mounting plate (the part that screws into the cabinet frame).
* Overlay: Concealed hinges like this come in different 'overlays' (Full Overlay, Half Overlay, or Inset), which determine how the door sits relative to the cabinet frame. The image alone doesn't definitively tell us the overlay, but the common 110° opening angle is typical for these designs.
The soft-closing feature makes it a popular choice for furniture where quiet operation is desired.
