Stainless steel is an alloy material containing iron, carbon, nickel and chromium, and a non-magnetic stainless steel material. Stainless steel has better malleability. Because of the austenite structure of stainless steel, it has strong corrosion resistance in many environments, good fracture resistance caused by corrosion caused by metal stress, and its material properties are not affected by heat treatment.
In stainless steel, there are two opposite forces acting at the same time: ferrite forming elements continuously form ferrite and austenite forming elements continuously form austenite. The final crystal structure depends on the relative amount of the two types of additives. Chromium is a ferrite forming element, so there is a competitive relationship between chromium and austenite forming elements in the formation of crystal structure of stainless steel. Because both iron and chromium are ferrite forming elements, stainless steel is a completely ferritic stainless steel with magnetic properties. In the process of adding the austenitic forming element-nickel to the Fe-Cr stainless steel, the austenite formed will gradually increase with the increase of nickel composition until all ferrite structures are transformed into austenitic structures, thus forming stainless steel.

Scope of use
Water ring vacuum pumps and compressors are widely used in petrochemical, pharmaceutical, food, sugar industry and other fields. Because the gas compression process is isothermal in the working process, it is not easy to occur danger when compressing and sucking flammable and explosive gases, and its application is more extensive.
Coaxial direct connection design of pump saves space and is easy to install.
The mechanical seal is used as the standard configuration, eliminating leakage and easy maintenance.
It runs smoothly and has low noise.
Unified corrosion resistance design, bronze impeller improves the corrosion resistance of the pump, stainless steel material is more suitable for more rigorous applications.
The unique flexible exhaust design does not produce over-compression, which ensures that is efficient in its performance range.

304 stainless steel rotary vane vacuum pump is a single stage rotary vane oil seal vacuum pump. Basic equipment for extracting gases from sealed containers to obtain vacuum. The pump can be used for repairing air conditioning and refrigeration equipment, suction devices of medical instruments, vacuum packaging, vacuum plastic suction, physical and chemical experiments, and small devices requiring vacuum environment. It can also be used as a front-stage pump for small oil booster pumps, oil diffusion pumps, molecular pumps, etc. The pump is not suitable for the removal of corrosive ferrous metals, chemical reactions on the pump oil, gas containing particulate dust, as well as excessive oxygen, explosive toxic gases. It can not be used as a transmission pump (i.e. pumping from one container to another).
Scope of use:
1. Vacuum 6 Pa;
2. Small size, light weight and low noise;
3. It can be used independently or as a pre-pump of booster pump, diffusion pump, molecular pump, maintenance pump and titanium pump.
4. It can also be used in the manufacture of electric vacuum devices, vacuum welding, printing, plastic absorption, refrigeration equipment repair and instrument matching.
5. It can not be used to extract gases with excessive oxygen, explosive, corrosive to metals, chemical reactions to vacuum oil, particles and dust, nor can it be used as conveyor pumps and compression pumps.
