Now let's compare the low carbon steel and stainless steel shelving in terms of raw materials:

　　1. Low carbon steel shelf, also known as mild steel, with carbon content ranging from 0.10% to 0.30%, is easy to accept various processing, such as casting, welding and cutting. It is often used to make chains, rivets, bolts, shafts, etc. Carbon steel with carbon content less than 0.25% is also called mild steel because of its low strength and hardness. It contains most ordinary carbon structural steels and some good carbon structural steels. Most of them are used for engineering structural parts without heat treatment, and some are used for mechanical parts requiring wear resistance after carburizing and other heat treatment. Low carbon steel is a very strong and resistant metal material. The cost of low carbon steel is relatively low, but its hardness is good. It is very suitable for writers or commercial shelves and display shelves.

　　2. Stainless steel shelf. SUS304 stainless steel and SUS201 stainless steel are common in the market,

　　Stainless steel refers to the steel that can resist the corrosion of weak corrosive media such as air, steam and water and chemical corrosive media such as acid, alkali and salt, also known as stainless acid resistant steel. Stainless steel has two aspects: stainless steel and corrosion resistance, which are called stainless steel and corrosion resistance steel respectively, collectively referred to as stainless steel. General steel can be divided into

　　a. Low carbon steel, usually C% < 0.25%, is called low carbon steel, with low strength, good plasticity and weldability.

　　b. Medium carbon steel, with C% of 0.25 ~ 0.60%, is called medium carbon steel. It has high strength, but poor plasticity and weldability.

　　c. High carbon steel, C% > 0.60%, is called high carbon steel. The plasticity and weldability are very poor, but there will be high strength and hardness after heat treatment. The carbon content of high carbon steel is between 0.6% - 2%, and more than 2% is cast iron. The standard of stainless steel is more than Cr12, which indicates whether it is resistant to corrosion and corrosion by containing Cr and Ni respectively. It can also be divided into low carbon and high carbon. The primary function of carbon in general steel is to add hardness. In stainless steel, it affects the function of intergranular corrosion. Of course, hardness can also be added.

　　In a word, the difference between low carbon steel and stainless steel mainly lies in the strength of anti rust and anti-corrosion ability; The anti rust and anti-corrosion effect of stainless steel is much stronger than that of carbon steel, so the price of stainless steel is higher than that of low carbon steel (especially steel). The quality of the raw materials of the shelf is to select the appropriate steel according to the purpose, rather than simply according to the concave convex of the steel price.
