ASTM A709 bridge steel plate,P460NH steel is a normalized weldable fine grain steel. Executive standard: EN10028-3, steel number: 1.8935. P460NH steel is alloy special steel for pressure equipment. P460NH steel has good plasticity, toughness, cold bending performance and welding performance. P460NH steel plates are usually delivered in normalized condition. According to the negotiation between the supplier and the buyer, normalizing rolling can be used instead of normalizing. In this case, the sample shall be subject to simulated normalizing according to the agreed test frequency to verify that the performance meets the requirements.
ASTM A709 bridge steel plate,12Cr1MoVR steel plate is suitable for medium and high temperature pressure vessels, and implements GB713-2014 standard. 12Cr1MoVR pressure vessel plate is usually delivered in normalizing + tempering state. According to the special agreement at the time of order, 12Cr1MoVR steel plate can also be delivered in annealing or tempering state, which significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
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 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.ASTM A709 bridge steel plate
ASTM A709 bridge steel plate,According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.
