CCSD32-Z25 ship steel plate

CCSD32-Z25 ship steel plate

CCSD32-Z25 ship steel is a kind of hull structure steel plate additional Z to the performance. Hull structure steel plate additional Z to the performance not only has good comprehensive mechanical property, welding performance and processing properties corresponding grade structural steel (grade mother steel), but also has good lamellar tearing resistance.
