ASTM A240 UNS S32205 Duplex Stainless Steel Strips

What Are ASTM A240 UNS S32205 Duplex Stainless Steel Strips

ASTM A240 UNS S32205 duplex stainless steel strips

ASTM A240 UNS S32205 duplex stainless steel strip is a chromium-nickel- molybdenum-nitrogen stainless steel strip.

It is also called duplex 2205 stainless steel strip.

UNS S32205 strip has high strength and corrosion resistance at temperatures up to 316°C.

The yield strength of duplex UNS S32205 stainless steel strip is more than twice that of normal austenitic stainless steel strip. This feature enables engineers and designers to reduce weight when designing related products, making this strip more cost-effective than 316L stainless steel strip and 317L stainless steel strip.

Waht Are ASTM A240 UNS S32205 Duplex Stainless Steel Strips Applications

Due to the super strength and excellent corrosion resistance features, quality grade UNS S32205 stainless steel strip is widely used for below applications.

  1. Pressure vessels, high pressure storage tanks, high pressure pipelines
  2. Heat exchangers fittings, chemical processing industry
  3. Oil and gas pipelines,
  4. Sewage treatment system

What’s The Difference Between 2205 And 2507 Stainless Steel Strip?

The standard of duplex stainless steel 2205 is ASTM A240.

Duplex stainless steel 2205 alloy is a duplex stainless steel composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy.

It has high strength, good impact toughness and good overall and local stress corrosion resistance.

2507 (UNS S32750) super duplex stainless steel is composed of 25% chromium, 4% molybdenum and 7% nickel.

It has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and sea equipment.

It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient.

The high content of chromium, molybdenum and nitrogen makes it highly resistant to pitting corrosion, crevice corrosion and uniform corrosion.

The 2205 and 2507 stainless steel strip has become an important engineering material during past decades. Do you know what is the difference between two stainless steel strips?
