Cause of corrosion pits on 09cuptire-a equivalent

EN10025-3 S460NL material is a hot rolled low carbon manganese steel. It has min. 460Mpa yield strength and low temperature impacting at -50℃ with minimum energy 27 J. 09CUPTIRE-A equivalent, S460NL also has good weldable property and possess good impact resistance (also in sub-zero temperatures). We supply S460NL steel plate for deep oceans, bulit the tanks or structural parts of nuclear submarine all over the world. Large stock of S460NL hot rolled plate available in India, Bangladesh, Malaysia, Nigeria, South Africa & UAE.

Will 09CUPTIRE-A equivalent, stainless steel rust? Under normal conditions, stainless steel will not rust. It has a great relationship to the composition of stainless steel. In addition to iron, stainless steel has chromium, nickel, aluminum, silicon and so on elements. Scientists have found that the more uniform the internal structure of steel, the closer the various components are linked, and the more difficult it is for corrosive substances to invade. In addition, a layer of oxide protective film is attached to the surface of stainless steel, which is just like wearing armor on steel, it is not easy to rust.

Ultrasonic flaw detection emits ultrasonic waves to the 09CUPTIRE-A equivalent steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the 09CUPTIRE-A equivalent steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
