Industrial Stainless Steel Seamless Tube A213 TP304 High Strength
For Heat Exchanger
In the damp industrial or coastal atmospheres of Europe, they
perform better than TP 304/304L and ferritic grades. In low
temperature seawater they offer limited resistance to pitting but
are susceptible to crevice attack. Their short- and long-time
properties at elevated temperatures are also superior to those of
comparable TP304/304L grades.
