Duplex Steel 2205 Stainless Pipe Tee Asme B16.9 Dn10-Dn600 Seamless Or Welded

Duplex Steel 2205 ASME B16.9 Fittings DN10-DN600 Stainless Steel Tee Seamless Or Welded

The yield strength of 2205 duplex stainless steel is more than double that of ordinary austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more affordable than 316 and 317L. This alloy is particularly suitable for use in the -50°F/+600°F temperature range. For applications outside this temperature range, this alloy can also be considered, but there are some limitations, especially when applied to welded structures.

The difference between duplex 2205 stainless steel plate and austenitic 304 stainless steel plate

1) The yield strength is more than double that of ordinary austenitic stainless steel, and it has the necessary forming requirements.

Sufficient plasticity. The wall thickness of storage tanks or pressure vessels made of duplex stainless steel is 30-50% lower than that of commonly used austenite, which is conducive to reducing costs.

2) It has excellent resistance to stress corrosion cracking. Even the duplex stainless steel with the lowest alloy content has a higher resistance to stress corrosion cracking than austenitic stainless steel, especially in the environment containing chloride ions. Stress corrosion is a prominent problem that ordinary austenitic stainless steel is difficult to solve.

3) The corrosion resistance of the most commonly used 2205 duplex stainless steel in many media is better than that of ordinary 316L austenitic stainless steel, while the super duplex stainless steel has extremely high corrosion resistance, and in some media, such as acetic acid, 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 equivalent 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 connecting with carbon steel and has important engineering significance, such as the production of clad plates or linings.

6) No matter under dynamic load or static load condition, it has higher energy absorption capacity than austenitic stainless steel, which has obvious advantages for structural parts to cope with sudden accidents such as collision, explosion, etc., and has practical application value.

Compared with austenitic stainless steel, the disadvantages of duplex stainless steel are as follows:

1) The universality and versatility of application are not as good as that of austenitic stainless steel, for example, its use temperature must be controlled below 250 degrees Celsius.

2) Its plasticity and toughness are lower than that of austenitic stainless steel, and its cold and hot working processes and forming properties are not as good as that of austenitic stainless steel.

3) There is a medium temperature brittle zone, and it is necessary to strictly control the process system of heat treatment and welding to avoid the appearance of harmful phases and damage the performance.
