2205 Stainless Steel Plate
2205 stainless steel plate is derived from 022Cr22Ni5Mo3N and has a narrower interval. Two-way the most common types of steel used in steel, copy of curing, carbon dioxide and hydrogen chloride environment has the tolerance, can be hot and cold processing and forming, welding performance lh-zd good, used as a structural material, instead of using 304 and 316.Chemical composition: C≤0.030 Mn≤2.00 Si≤1.00 p≤0.030 S≤0.020 Cr 22.0 ~ 23.0 Ni 4.5 ~ 6.5 Mo3.0 ~ 3.5 N0.14 ~ 0.20(austenitic ferrite body type).
(1) yield strength is more than twice as high as ordinary austenitic stainless steel, with enough plasticity and toughness to form. The wall thickness of storage tank or pressure vessel made of duplex stainless steel is 30-50% lower than the commonly used austenitic body wall thickness, which is conducive to cost reduction.
(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 the austenitic stainless steel, especially in the environment containing chloride ions. Stress corrosion is a difficult problem to solve in ordinary austenitic stainless steel.
1, the universality and versatility of the application is not as austenitic stainless steel, such as its use temperature must be controlled below 250 degrees Celsius.2, its plasticity toughness is lower than austenitic stainless steel, cold, hot processing technology and forming performance is not as good as austenitic stainless steel.
2205 stainless steel plate.Duplex stainless steel has twice the compressive strength of austenitic stainless steel and can be designed to reduce its weight compared to 316L and 317L. Alloy 2205 is particularly suitable for the temperature range of -50 °F/+600°F, and can also be used at lower temperatures under strictly limited conditions.
Never be afraid to bother me, it is no matter if you have the regular supplier, just take a consideration while our products are the best price and high quality.
