A203GrD steel plate belongs to ultra-low temperature container plate. ASTM A203 is a low-nickel alloy steel, including five grades A, B, D, E, and F. Among them, Grades D, E, and F have a nominal nickel content of 3.5%, commonly known as 3.5Ni steel. A203D/E/F steel has good impact toughness and mechanical properties in a low temperature environment, and is usually used in a low temperature environment of -70～-101℃ (the tempered state can reach -107℃).
40Cr steel belongs to alloy structural steel. TM rolled GL-FH 32 shipbuilding steel, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.
The visual inspection (VI) or visual detection method is to scan the surface of the steel plate through a machine vision system (CCD line camera), convert the captured target into an image signal, and send it to a dedicated image TM rolled GL-FH 32 shipbuilding steel processing system, which converts it into a digital signal based on pixel distribution and brightness, color and other information. The system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on the spot according to the result of the discrimination. Visual detection method can achieve online high-speed detection for the TM rolled GL-FH 32 shipbuilding steel steel plate.
TM rolled GL-FH 32 shipbuilding steel, SS400 steel is one of the most commonly used hot rolled general structural steel. SS400 steel’s mechanical properties is yield strength more than 225-235MPa, tensile strength 360-510Mpa and 340-470Mpa. For SS400 steel, the C element content is 0.2% max, the Mn element content is 1.40% max, the P element content is 0.045% max, the S element content is 0.045% max.
