Overview
430 stainless steel contains trace amounts of manganese, silicon,
carbon, sulfur, and phosphorus.This chemical composition means that
430 stainless steel contains high thermal conductivity.It is
suitable for use high polishing decorative uses in mild atmospheric
environment, such as building interior decoration, heavy oil burner parts, household
appliances, home appliance parts, etc.

Application
1. Construction field: 430 stainless steel pipes are widely used in
the construction field for indoor and outdoor decoration and
structure. It can be used to make stair handrails, doors and
Windows, railings and other metal products. Because of its bright
appearance and strong corrosion resistance, it can maintain a good
surface state for a long time, so it is widely used in the
construction field.
2. Petrochemical and chemical industry: 430 stainless steel pipes
are used to transport various corrosive media in the petrochemical
and chemical industry. Because of its excellent corrosion
resistance, it can withstand high temperature and high pressure
environment, so it is widely used in petroleum, chemical, natural
gas and other fields of pipeline system. In addition, 430 stainless
steel pipes can also be used to make chemical equipment, reactors
and storage tanks.
3. Energy industry: In the energy industry, 430 stainless steel
pipes are widely used to transport oil, natural gas and other
fluids. Stainless steel material has corrosion resistance, which
can effectively prevent corrosion and leakage inside the pipeline
to ensure the safe transmission of energy.
4. Pharmaceutical industry: 430 stainless steel pipe is widely used
in the pharmaceutical industry. It can be used to make medical
instruments, surgical instruments and medical equipment. Stainless
steel has good sanitary properties and corrosion resistance...
Advantage
1. Formability, economy, corrosion resistance, oxidation resistance
and other functions
2. Do not add nickel and molybdenum and other precious alloys, with cost
advantages
3. Ferritic stainless steel has high ferromagnetism and thermal
conductivity, which is very suitable for the use of heat exchange
