Auto Parts

Usage: Hinges, also called hinges or doors, are used to connect two solids and allow the two to do relative rotation between the mechanical device, the main feature is to bring the buffer function when the cabinet or door is closed, to minimize the noise caused by the collision with the body when closing. Automobile hinges are generally used in automobile doors, engine covers, tail box covers, fuel tank cover hinges, etc. The mounting surface between the door hinge and the door and the body must be flat; If the door hinge is bolted, the relative size between the bolt mounting holes of the body and the door parts must be in line with the size and stable.

Material: 16Mn 16Mn steel belongs to carbon manganese steel, the carbon content is about 0.16%, and the yield point is equal to 343mpa (the strength level belongs to 343mpa grade). 16Mn steel has less alloy content and good weldability, so it generally does not need to be preheated before welding. However, since the hardening tendency of 16Mn steel is slightly larger than that of mild steel, preheating measures are required to prevent cold cracks when welding at low temperatures (such as winter open-air operations) or on large rigidity and large thickness structures.
