It is from the 30’s in the twentieth century that stainless steel began to be used in architecture, as the stainless steel has good anti-corrosion nature and excellent decoration nature, and is easy for cleaning and cheap for maintaining, and has a long life, and so on; now it is already widely used in buildings including residential building, city planning building, gymnasiums, parks, pleasure grounds and commercial buildings, etc. The steel type in use is mainly 0Cr18Ni9, under the damp seawater environment, use the 0Cr17Ni12Mo2，0Cr17 can also be used inside the house.

3. The application of stainless steel in bridges, tunnels and landscapes.
Stainless steel has been successfully used in constructing bridge, tunnel projects, the life span of stainless steel bridge can be much higher than common steel bridge, and has more beautiful appearance. Besides, stainless steel reinforced concrete has been used in architecture infrastructure, its life span can be more than 100 years, 3 times of common reinforced concrete, and it is especially adaptable to the corrosive environment of the sea and cold season deicing salt. The typical application examples of stainless steel in bridges, tunnels, and reinforced concrete and landscape projects are shown in the following table:

The application examples of stainless steel in bridges, tunnels, and landscape projects

Name	Material brand	Remark
Progreso Trestle, Mexico (1941)	0Cr18Ni9，steel reinforcement (φ30mm)	Perfect up to now

Apart from that the above stainless steel is used in edifices, bridges, landscape projects, there are other objects like components for reinforcing architecture, stone anchoring objects and large sums of fastening pieces which also are composed of stainless steel, the main brands are 0Cr18Ni9，0Cr17Ni12Mo2 and 0Cr17, etc. E.g. in American California, the 0Cr17Ni12Mo12 stainless steel anchoring piece that is 9 meters long is used to reinforce the clay bank.
