S460N and S460NL normalized structural steel plate

Posted:10/27/2011 2:04:46 PM

With minimum yield strength 460Mpa,S460N steel and S460NL steel can work in the normal strength situiations when construction.
Besides the impacting test and Normalized heat treatment, customers usually indicate the following technical terms in their P/O:
I. PWHT (Simulated post-weld heat treatment), instruct temperature and time when rolling.
II. Ultrasonic examination or named UT.
III. DWTT for steel plate straight test.
IV. The third party inspection.
Our mill definately would issue all the above tests result on our MTC paper for customers' checking when finished rolling. We give the chemical elements contains sheet as bellows:
