What are the differences between the stainless steel materials of the Pin , 201, 303 and 304?

201 stainless steel presents a darkish bright color and is prone to rusting. 303 has better rust prevention ability than 201, but it is inferior to 304. 304 stainless steel has excellent corrosion resistance and rust prevention ability, but its price is 304 > 303 > 201.

What are the differences Plastic-top chains with plastic plates materials Physical and chemical properties？

Polyoxymethylene (POM), also known as acetal,polyacetal, and polyformaldehyde,It is an engineering thermoplastic used in precision parts requiring high stiffness, low friction and excellent dimensional stability. 

POM is characterized by its high strength, hardness and rigidity to −40 °C. POM is intrinsically opaque white because of its high crystalline composition but can be produced in a variety of colors.Working temperature  −40 °-80°C，

Polypropylene (PP), also known as polypropene, It is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.

Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance.Working temperature 0 °-100°C，It is more wear-resistant compared to POM, and it is also more resistant to acids and alkalis, with better corrosion resistance.
