5/16 Duplex 2507 Seamless Stainless Steel Coils
5 / 16 * 0.049 Duplex 2507 Seamless Stainless Steel Coiled Control Line Tubing
Super duplex stainless steel 2507 (S32750) is a kind of stainless steel that PREN>40, containing 25%Cr and high molybdenum (>3.5%), high nitrogen (0.22% ~ 0.30%). 2507 duplex stainless steel has strong strength and corrosion resistance. It is mainly used in chemical processing, petrochemical industry and subsea equipment.It has strong resistance to chloride corrosion, high thermal conductivity and low coefficient of thermal expansion.The higher the content of chromium, molybdenum and nitrogen, the higher the resistance to spot corrosion, crack corrosion and general corrosion.
Duplex 2507 control line tubing is also one of our most competitive products, we have rich processing and supply experience. Our products are standardized and international, meeting ASTM A789 and all relevant industry standards, and have been exported to overseas markets in large quantities for many years.
