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.
CCSD32-Z25 shipbuilding steel chemical composition %
Grade | C max | Si max | Mn | P max | S max | Als min | Ti max | Cu max | Cr max | Ni max | Mo max |
| D32-Z25 | 0.18 | 0.50 | 0.90-1.60 | 0.035 | 0.035 | 0.015 | 0.02 | 0.35 | 0.20 | 0.40 | 0.08 |
Note: Generally speaking CE will be ≤ 0.40%. If the delivery condition is TMPC, the CE will be : ≤ 0.36% (thickness ≤ 50mm),≤0.38%( when the thickness >50-100). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
