Duplex stainless steel get their name from the fact that they contain both a ferritic and austenitic microstructure. The effect of thermal expansion is most noticeable where components are restrained, as the expansion results in buckling and bending. Contact Us At [emailprotected] For Best Price. This expansion coefficient not only varies between steel grades, it also increases slightly with temperature. Reply. Ferritic - such as grades 409, 430 and 439.

This expansion coefficient not only varies between steel grades, it also increases slightly with temperature. Stainless steel is an alloy of iron that is resistant to rusting and corrosion.It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Grade 304 has a coefficient of 17.2 x 10-6 /C over the temperature range 0 to 100C but increases above this temperature. Stainless steel flatware is often found in 18/10, 18/8, and 18/0. Although not formally defined, it is gener-ally accepted that the lesser phase will be at least 30% by volume. Newer to the world of stainless steel grades is the duplex category. Related Papers. Duplex stainless steel get their name from the fact that they contain both a ferritic and austenitic microstructure. Thank. Medium carbon steels are stronger than mild steel, but with an increase in carbon content, the formability reduces. The Stainless Steel Welded Tube ASTM A554 is good to be used with welded applications.
