The role of chromium in ASTM A537CL1 vessel steel plate

The addition of chromium in ASTM A537CL1 vessel steel plate can significantly improve the oxidation resistance and corrosion resistance of A537CL1 steel materials. Chromium can improve the performance of A537CL1 steel.

In ASTM ASTM A537CL1 vessel steel plate, the main function of chromium is to improve the hardenability and comprehensive mechanical properties of A537CL1 steel material. That is to say, under certain strength level, ASTM A537CL1 steel plate will have better plasticity and toughness.

At the same time, chromium is an element with passivation tendency. Therefore, adding chromium to ASTM A537CL1 vessel steel plate will enable the steel to get better corrosion resistance and oxidation resistance.
