Light guide fixture plate, material 6061-T6 aluminum, CNC machined, surface brushed finish, used for fixing light guides during vacuum coating process...
The blackening of aluminum parts is not "rust", but a layer of dense black oxide film is generated on the surface through chemical reaction, which has three functions of anti-corrosion, wear resistance and beauty.
Aluminum part chamfering is not appearance modification, but the rigid requirements of safety, assembly, strength and technology. If the corner does not fall, it may cause assembly jamming at the least and part scrapping at the worst.
The working principle of stainless steel threaded valve body joints is to control the smoothness or blockage of the valve by rotating the valve core. The valve body joint can be integrated or combined. Next, let's learn about the relevant knowledge of non stainless steel threaded valve body joints
(1) Stainless steel valves should be prevented from coming into contact with other metals, and attention should be paid to preventing foreign objects such as garbage from entering. They should be stored in a well ventilated environment. (2) In order to protect the inner gasket of the ball valve joint, the ball valve should be in the fully open state, and the gate valve, globe valve, and check valve should be stored in the fully closed state.
The carbon content is 0.42% to 0.50%. After quenching and tempering, the strength, toughness and wear resistance are balanced. It can be surface high-frequency quenched, and the surface hardness can reach HRC55 to 58. The core part maintains toughness, and is wear-resistant and impact-resistant. It is suitable for bearing sleeves, sleeves, gears and other stressed components. Small parts can be stabilized in shape through water quenching, and large parts can be stabilized through normalizing. The heat treatment process is mature and the product yield is high...
