Common corrosion types and causes of TM rolled GL-AH 40 hull steel plate

TM rolled GL-AH 40 hull steel plate, Shipbuilding steel plate refers to hot-rolled steel for the manufacture of ship structures produced in accordance with the requirements of the TM rolled GL-AH 40 hull steel plate construction society. Often used as a special steel ordering, scheduling, sales, a ship including ship plates, steel and so on.

At present, the overall market demand of TM rolled GL-AH 40 hull steel plate is weak, the purchase intention of end users is not strong, and the purchase is basically on demand. The market transaction of TM rolled GL-AH 40 hull steel plate is relatively general, and some markets have declined. However, the overall market inventory of TM rolled GL-AH 40 hull steel plate is not high, coupled with the strong willingness of steel mills to support price, and the high resource cost in the later stage, therefore, businesses are not willing to sell of TM rolled GL-AH 40 hull steel plate at too low price. On the whole, the short-term market of TM rolled GL-AH 40 hull steel plate is expected to be dominated by high fluctuations.

Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the TM rolled GL-AH 40 hull steel plate steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This TM rolled GL-AH 40 hull steel plate method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.

Available steel plate types: TM rolled GL-AH 40 hull steel plate, carbon structural steel plate, low alloy high strength steel plate, bridge steel plate, building structural steel plate, shipbuilding and offshore platform steel plate, boiler and pressure vessel steel plate, mold steel plate, alloy structural steel plate, oil and gas transmission pipeline steel plate, high strength and high toughness steel plate, corrosion-resistant steel plate, composite steel plate, wear-resistant steel plate, etc.
