65Mn spring steel is mainly used for various flat and round springs, cushion springs, spring springs, and can also be used to make spring rings, valve springs, clutch reeds, brake springs and cold-drawn steel wire cold coil springs, etc.
430 is a kind of stainless steel, which has very good corrosion resistance. Compared with austenitic stainless steel, it has better thermal conductivity and smaller thermal expansion coefficient. The mechanical properties of welding parts are better, and it is safe and non-toxic. tendency to corrode.
According to the processing method, stainless steel is divided into: steel for pressure processing and steel for cutting; according to the structure characteristics, it is divided into five types: austenite type, austenite-ferrite type, ferrite type, martensite type and precipitation hardening type .
Carbon steel pipe is a kind of steel pipe alloy. It is made of solid round steel or steel ingot as raw material, and then made into capillary tube through perforation process, and then made by hot rolling or cold drawing technology.
High carbon steel is used to manufacture metal structural parts, carburized or carbonitrided parts with low core strength requirements, tie rods, connecting rods, hooks, couplers, bolts, nuts, sleeves, shafts and connectors; C , Class D is used to manufacture important welded structural parts.
The so-called duplex stainless steel is that in its solid solution structure, the ferrite phase and austenite phase account for about half, and the content of the minimum phase generally needs to reach 30%, so it has both the properties of ferritic stainless steel and austenitic stainless steel features.
