HOT ROLLED STAINLESS SHEET A240 TP321

Stainless steel plate a240 321 is equal to chinese stainless steel grade 0Cr18Ni10Ti,stainless steel sheet a240 tp321 has better resistance to grain boundary corrosion and high temperature strength due to the adding of Titanium element in chemical composition,and also Hot rolled stainless sheet A240 TP321 is much better than A240 316L stainless sheet in high temperature.

In stainless A240 321 steels,there are stainless steel sheet A240 321 and stainless steel sheet A240 321H,the main difference between these two grades are carbon percentage in chemical composition,A240 321H requires minimum 0.04% and maximum 0.10% carbon contains,but A240 321 only need carbon contains maximum 0.08% is okay,not requires minimum value.
