Popular Design for Monel Bar - Duplex Stainless Steel 2205 – Sekonic

Common Trade Names: 2205, UNS S32205, 00Cr22Ni5Mo3N,W.Nr 1.4462

 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.The yield strength of 2205 duplex stainless steel is more than twice that of ordinary austenitic stainless steel . This feature enables designers to reduce weight when designing products, making this alloy more cost-effective than 316 and 317L. This alloy is particularly suitable for the temperature range of -50°F/+600°F.

Why Duplex Stainless Steel 2205 ?

1) The yield strength is more than twice that of ordinary austenitic stainless steel, and it has the necessary requirements for forming
Sufficient plasticity. The wall thickness of storage tanks or pressure vessels made of duplex stainless steel is 30-50% less than that of commonly used austenite, which is beneficial to reduce costs.
2) It has excellent resistance to stress corrosion cracking. Even the duplex stainless steel with the lowest alloy content has higher resistance to stress corrosion cracking than austenitic stainless steel, especially in an environment containing chloride ions. Stress corrosion is a prominent problem that is difficult to solve for ordinary austenitic stainless steel.
3) The corrosion resistance of 2205 duplex stainless steel, which is most commonly used in many media, is better than ordinary 316L austenitic stainless steel, while super duplex stainless steel has extremely high corrosion resistance. In some media, such as acetic acid and formic acid It can even replace high-alloy austenitic stainless steel and even corrosion-resistant alloys .
4) It has good local corrosion resistance. Compared with austenitic stainless steel with the same alloy content, its wear corrosion resistance and fatigue corrosion resistance are better than austenitic stainless steel.
5) The coefficient of linear expansion is lower than that of austenitic stainless steel , which is close to that of carbon steel. It is suitable for connection with carbon steel and has important engineering significance, such as the production of composite plates or linings.
6) Whether under dynamic or static load conditions, it has a higher energy absorption capacity than austenitic stainless steel. This is for structural parts to cope with sudden accidents such as collisions and explosions. Duplex stainless steel has obvious advantages and has practical application value.
