CCSDH890 steel plate flaw

detection A and Z direction steel plates should be ultrasonic flaw detection, and the flaw detection level should be specified in the contract.

B. According to the requirements of the buyer, other steel plates can also be subjected to non-destructive inspection by agreement between the supply and demand parties.

In the process of use, the performance of items and steel plates will not be well displayed because of bad weather, and the results often occur are catalysis, cracking, fracture, deformation, etc

However, after the steel plate has low-temperature impact performance, it can work in the cold climate of the corresponding temperature and still maintain the specific performance and state of the steel plate itself, so it is still very necessary
to select the steel plate grade in some cold areas
CCSDH890 there are two levels of steel plate (DH890=-20 °C low temperature impact)
