Chemical composition and standard of 347 steel plate

The main chemical composition of 347 steel plate includes chromium (Cr), nickel (Ni) and other elements, and contains a certain amount of carbon (C). The corresponding standard is ASTM A240/240M-2018, which specifies the technical specification for chromium and chrome-nickel stainless steel plates, sheets, and strips used in the manufacture of pressure vessels and for general purposes. In addition, the US UNS number of the 347 plate is S34700, and the ASTM type or grade is 347.

Typical characteristics of 347 steel plate

Good workability: 347 steel plate has good workability and can be formed and processed by conventional metal processing technology.

High temperature performance: Due to its high carbon content, 347 steel plate has good strength and creep resistance at high temperatures.

Corrosion resistance: 347 steel has similar corrosion resistance to 304 and 316 stainless steel and is suitable for a variety of environments.

Resistance to stress corrosion cracking: The high carbon content helps to improve the resistance to stress corrosion cracking of steel plate 347.

Weldability: 347 steel plate may need to be annealed after welding to restore its properties, because the high carbon content makes it prone to hardening after welding.

347 steel plate is widely used in many fields

Chemical field: Used to manufacture chemical equipment and components, which can resist the corrosion of a variety of chemical substances.

Petroleum: Used to manufacture oil extraction and processing equipment that can maintain stable performance in high temperature and high pressure environments.

Pharmaceutical field: Used in the manufacture of medical devices and instruments to ensure their excellent corrosion resistance and biocompatibility during use.

Food field: Used to manufacture food processing equipment and containers to ensure food hygiene and safety.
