Super Duplex Stainless Steel Tubing Pipe Customized 304 316 2mm
Product Description
Overview:
The relatively high chromium, molybdenum and nitrogen content of duplex stainless steels also gives them good resistance to chloride pitting and crevice corrosion, and their duplex structure is an advantage in environments where chloride stress corrosion cracking can occur.
If the microstructure of duplex stainless steel contains at least 30% ferrite, its resistance to chloride stress corrosion fracture is far better than that of austenitic stainless steel 304 or 316. However, ferrite is sensitive to hydrogen embrittlement, so in environments or applications where hydrogen may enter the metal and cause hydrogen embrittlement, duplex stainless steel does not have high corrosion resistance.
