Steel Q345R (HIC) is a Q345R pressure vessel plate with hydrogen induced cracking resistance test. Q345R(R-HIC) plate is based on Q345R (HIC) and SSCC test, namely sulfide stress corrosion test. The delivery status of Q345R (HIC) and Q345R Q345R(R-HIC) plate is normalizing, - 30 ℃ impact, level I flaw detection, process reference standard GB713-2014. A131 EH40 ship steel plate, Q345R (HIC) and Q345R (R-HIC) plates are smelted by electric furnace + refining outside the furnace. The smelting process is Ca-treated, and should be intrinsically fine-grained steel. The actual grain size is 5 or above.
Q245R boiler steel plate introduction: Q is the first letter of "Qu" Chinese Pinyin; Number 245 is the yield strength value; R: is the first character of "Rong" Chinese Pinyin. Q245R steel is a special plate for pressure vessels and boilers with a yield strength of 245MPa. It has outstanding mechanical properties and processability. If you have special requirements, our company can supply Z15, Z25, Z35 and other Z performance tests.
As the thickness and hardness of A131 EH40 ship steel plate increase, the tendency to crack at the cutting edge increases. In order to prevent the A131 EH40 ship steel plate from cutting cracks, preheating should be carried out before A131 EH40 ship steel plate cutting. Special attention should be paid to preheating to make the entire A131 EH40 ship steel plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole A131 EH40 ship steel plate cannot be preheated, the partial preheating method can be used instead.
