Moreover, the plate produced from ASTM A240 UNS S31803 is a good choice for use in marine engineering, due to the alloys high resistance to stress related corrosion cracking (SCC) in chloride containing environments. The mechanical properties of this dual microstructured austenitic sheets are more than grade 304.
For instance, the Rockwell hardness is valued at 31 and the materials yield strength is about 65 KSI. And the melting point of the shim stock is at a temperature of 1440 °C.With a significantly higher nickel content, the ASME SA 240 S32205 plates have a PREN value of more than 34, which means the alloy has good resistance to pitting conditions.
What is ASTM A240 Type 2205 Sheet?
This chromium-nickel based stainless steel grades such as Alloy 2205 covered by specification ASTM A240. This specification envelopes plates, sheets, and strips that have been deliberated with the purpose of being used in pressure vessels and for general applications as well. Aside from the chemical composition specified, the ASME SA 240 S31803 sheets are required to conform to the mechanical properties specified herein.
