EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll GL-D40 hull steel plates, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.
The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, GL-D40 hull steel plates. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.
With our own engineers, metallurgists and CAD draftsmen, we can provide total support from design through to machined casting. OEM precision casting investment GL-D40 hull steel plates casting auto parts, customized investment casting auto parts, custom precision casting automobile parts, truck casting iron fitting parts.Precision Casting: Tooling making → Wax pattern → Shall making → Chemical analysis → Pouring → Measurement & inspection → Heat Treatment → Processing → Finished product.
