Chemical composition and standards of AISI 329 stainless steel
SUS329 duplex stainless steel complies with JIS G4304 standard, and its core components are:
Chromium (Cr): 25%-28% (high chromium content improves oxidation resistance)
Nickel (Ni): 3%-6% (enhanced high temperature stability)
Molybdenum (Mo): 1%-2% (enhanced pitting resistance)
Other elements: balanced iron (Fe) and trace carbon (C), manganese (Mn)
This combination of ingredients gives the material a composite property of high strength, wear resistance, and stress corrosion resistance, making it the preferred alloy for harsh industrial environments.
1.Ultra-high strength and toughness
The yield strength is above 450MPa, which is better than 304/316 austenitic stainless steel, and takes into account the adaptability of plastic processing.
2.Full-scenario corrosion resistance
Resistant to corrosion by sulfuric acid, hydrochloric acid, seawater and chloride, suitable for acidic environments such as marine engineering and chemical reactors.
3.Synergistic effect of duplex structure
Austenite + ferrite duplex structure, with both resistance to crack propagation and resistance to stress corrosion cracking (SCC).
4.Easy processing and forming
Supports cold rolling, welding, stamping and other processes, and can be processed into complex parts such as pipes, valves, pump bodies, etc.
5.Long life economy
Reduce the frequency of equipment maintenance and reduce the cost of the entire life cycle.
