Application of 403 stainless steel pipe
In automobile manufacturing, it can be used for automobile turbine blades and other parts; in the field of mechanical manufacturing, it can be used to manufacture various high-stress parts, such as engines, transmission systems and other parts.
In pressure vessel manufacturing, it meets its requirements for material strength and certain corrosion resistance; in chemical equipment, it can work in some non-strongly corrosive environments, such as containers and pipelines for storing and transporting general chemical raw materials.
Processing services
Including no processing, customized samples, deep processing (stamping, bending, etc.), rough processing (opening, striping, etc.) and other processing services. SUS403 stainless steel can be processed according to the specific needs of users to meet the shape and size requirements of various application scenarios.
