High quality ABS D40 submarine hull steel with heat treatment test

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

Good weldabilityBecause of its low carbon content, low alloy element content, good plasticity and low hardenability, this material ABS D40 submarine hull steel is not suitable to have quenching structure or crack at the weld. The cold and hot pressure processing performance is good. Because of its good plasticity and small deformation resistance, it is not easy to produce cracks after pressure processing. Good corrosion resistanceUnder various atmospheric conditions, it has higher corrosion resistance than carbon steel.

Non-destructive flaw detection of steel plates is a test method for inspecting the ABS D40 submarine hull steel surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used ABS D40 submarine hull steel steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.

ANDRITZ GROUP is the world's leading industrial group, with 29500 employees and more than 280 branches in more than 40 countries. We have cooperated with their Mexico company for many years about S355J2+N steel plates and cutting sectors. The S355J2+N steel plates ABS D40 submarine hull steel need to cut according to the drawing by standard tolerance, UT, MT and dimension request. The final application of the S355J2+N steel plates and cutting sectors are for assembling hydraulic machine.
