Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cold-rolled equivalent strength steel
Processing method determines primary classification over strength designation.
If fabricated into marine vessel components
Vessels and floating structures classified by function under Chapter 89.
If alloy steel shipbuilding grade
Grade 50W weather-resistant ship steel typically alloy composition moves to 7225.
