Eco-friendly material Small tolerance hinge pin with nut accessory type for Automatic assembly machine

Hinge pin

is a kind of standardized fasteners, which can be static fixed connection, can also be connected with the relative movement, mainly used for the hinge of two parts, usually form hinge pin lock with cotter pin, reliable work, easy to disassemble.

Commonly used material

Steel no.45

45 steel shaft parts are commonly used materials, it is cheap after quenching and tempering (or normalizing), can get better cutting performance, and can get higher strength and toughness and other comprehensive mechanical properties, after quenching surface hardness can reach 45 ~ 52HRC.40Cr and other alloy structural steel is suitable for shaft parts with medium accuracy and high rotating speed. After quenching and tempering, this kind of steel has better comprehensive mechanical properties.

No.45 steel is widely used in machinery and has good mechanical properties.But this is a medium carbon steel, the quenching performance is not good, 45 steel can be hardened to HRC42~46.So if you need the surface hardness, and want to play 45# steel superior mechanical properties, often quenching 45# steel surface (high-frequency quenching or direct quenching), so that you can get the required surface hardness.
