ASTM A131 DH40 steel

ASTM A131 DH40 steel

Shanghai Katalor Enterprises Co., Ltd, as a DH40 ship steel supplier, we can provide DH40 shipbuilding plate and DH40 profile steel.

DH40 shipbuilding steel plate standard size:

thickness: 4-150 mm

Width :1000-3800mm

Length :3000-120000mm

Besides ,we also have our own cutting machines to fabricate these goods ,the width and length of our steel plate can be cut as our customers’ requirement.

For DH40 steel, we can do pretreatment:

shot blast+shop primer

standard:ISO SA2.5 PSPC

primer coating thickness: 15-35 micro mm

Usage: rust clearning, rust protection.

DH40 steel plate chemical composition %:


Grade
C max Si max Mn P max S max Als min Ti max Cu max Cr max Ni max Mo max Nb V
DH40 0.18 0.50 0.90-1.60 0.035 0.035 0.015 0.02 0.35 0.20 0.40 0.08 0.02-0.05 0.05-0.10

Note: Generally speaking CE will be ≤ 0.40%. If the delivery condition is TMPC, the CE will be : ≤ 0.40% (thickness ≤ 50mm). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
