Comparison between stainless steel and carbon steel.
1. Density.
The density of carbon steel is slightly higher than that of ferrite and martensitic stainless steel, but slightly lower than that of austenitic stainless steel.
2. Resistivity.
The resistivity increases according to the order of carbon steel, Ferritic, martensitic and austenitic stainless steel.
3. The order of linear expansion coefficient is similar, austenitic stainless steel is the highest and carbon steel is the smallest.
4. Carbon steel, Ferritic and martensitic stainless steels are magnetic, while austenitic stainless steels are not magnetic, but their cold work hardening results in martensitic transformation. Heat treatment can be used to eliminate this martensitic structure and restore its non-magnetism.

Application of stainless steel.

1. Water industry: stainless steel is the best material for water industry, such as water preparation, storage, transportation, purification, regeneration, seawater desalination, etc., its advantages are corrosion resistance, earthquake resistance, water saving, sanitation (no rust and copper green), light weight (reduced 1 / 3), less maintenance, long life (40 years), low life cycle cost (LCC), etc., and it is a recyclable green environmental protection material.
2. Construction industry: in terms of architectural decoration, stainless steel is mainly used to cover exterior walls, interior and outer columns of high-rise buildings, handrails, floors, elevator panels, doors and windows, curtain walls and other internal and external decoration and components. After surface treatment, coloring and coating of stainless steel plate, the problems such as handprint after touch are solved, and the application range of stainless steel is further expanded.
3. Home appliance industry: in the home appliance industry, the large consumption of stainless steel is the inner cylinder of automatic washing machine, the inner tank of water heater, the inner and outer shell of microwave oven, the lining of refrigerator, and the use of Ferritic stainless steel. generally speaking, the ratio of stainless steel used in household appliances in Western Europe is larger, while in Asia, only Japan is close to the European level.
4. Environmental protection industry: industrial waste gas, garbage and water treatment equipment need to be made of stainless steel, and in the process of flue gas desulfurization, it is necessary to resist the corrosion of sulfur dioxide, chloride ion and iron ion, in absorption towers, coolers, pumps, valves, flue, etc., it is necessary to use duplex stainless steel and high-grade austenitic stainless steel another waste incinerator, wastewater treatment and other facilities, all need to be made of high-performance stainless steel.
5. Industrial facilities: the proportion of stainless steel used in industrial facilities in developed countries can generally reach 15% to 20%, but the proportion of applications in mainland China is still very small. Chemical, petrochemical, chemical fiber, paper, food, medicine, energy (nuclear power, thermal power, fuel cells) and other fields all need stainless steel with the improvement of the quality of domestic stainless steel products and the development of special brand products. In the future, the application of stainless steel in mainland industrial facilities is expected to increase year by year.
6. Automobile industry: the application field of stainless steel in mainland is mainly concentrated in the automobile industry, while in Europe and America, it is further expanded to be used in cars, buses, trains, subway cars, high-speed railway vehicles, etc., indicating that there is a huge space for the development of the vehicle industry.

Production according to customers request

Compared with carbon steel, austenitic stainless steel has the following characteristics:

1) High resistivity, about 5 times that of carbon steel.

2) the large coefficient of linear expansion is 40% larger than that of carbon steel, and the value of the coefficient of linear expansion increases accordingly with the increase of temperature.

3) low thermal conductivity, which is about 1 beat 3 of carbon steel.
