1/4" Steel Plate Hot Rolled 09CuPCrNi-A steel details

The difference between 09CuPCrNi-A steel details, Q420D steel and Q460D steel: Q420D steel has good mechanical properties and weldability, good cold and hot workability. Q420D steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts. 09CuPCrNi-A steel details, Q460D steel has high strength, good plasticity and toughness, good weldability and good cold and hot workability. Q460D steel is mainly used for manufacturing engineering machinery components, such as mining machinery, forklift truck, transport vehicle, bridge, medium and high pressure boiler and other large-scale welding structural parts.

Automobile girder steel is a kind of low alloy hot-rolled steel plate with thickness of 2.5-12.0 mm for manufacturing automobile girder (longitudinal beam and cross beam). Due to the complex shape of automobile girder, good stamping performance is required in addition to high strength and cold bending performance for automobile girder steel. The 09CuPCrNi-A steel details, medium thick and heavy steel plates are mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on.

Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This 09CuPCrNi-A steel details method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.
