Description

2507 stainless steel coil

2507 duplex stainless steel contains 25% chromium, 4% molybdenum, and 7% nickel. It has strong strength and corrosion resistance, and its main application areas are chemical processing, petrochemical, and subsea equipment. At the same time, it has excellent resistance to chloride corrosion, high thermal conductivity, and low thermal expansion coefficient. Also, the high content of chromium, molybdenum, and nickel makes it resistant to pitting, crevice corrosion, and uniform corrosion.

Product Description

The impact strength of 2507 duplex stainless steel is also very high. 2507 stainless steel should not be used for a long time at a temperature higher than 570°F, which will reduce the toughness of the stainless steel.

2507 duplex stainless steel has a high content of chromium and molybdenum, so it has better overall corrosion resistance to organic acids such as formic acid and acetic acid. At the same time, it also has strong corrosion resistance to inorganic acids containing chlorides.

316L stainless steel can’t be used in the hydrochloric acid environment, it may suffer local corrosion or overall corrosion. 2507 can be used in the diluted hydrochloric acid environment, with strong resistance to pitting and crevice corrosion.
