700mce hot rolled automotive steel surface cracks refer to the linear cracks on the surface of 700mce hot rolled automotive steel, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: 700mce hot rolled automotive steel surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
Advantages of NM360 wear-resistant steel plate: NM360 steel has high strength: generally its yield strength is above 300MPa. 2. High toughness: The elongation is required to be 15% -20%, and the room temperature impact toughness is greater than 600kJ / m ~ 800kJ / m. For large welded components, high fracture toughness is also required. 3. NM360 steel plate has good welding performance and cold forming performance. 4. Low cold and brittle transition temperature.
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 700mce hot rolled automotive steel 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.
700mce hot rolled automotive steel, S235JR VS S275JR VS s355jr plates in yield strength: For plate thickness ≤16mm, the min. yield strength of S235JR plates is 235 Mpa, S275JR plates is 275 Mpa, S355JR plates is 355 Mpa. The yield strength of S235JR S275JR S355JR plates reduces with the increasing of plate thickness. S235JR VS S275JR VS S355JR plates in tensile strength: For plate thickness 3-100mm, the tensile strength of S235JR plates is 360-510 Mpa, S275JR plates is 410-560 Mpa, S355JR plates is 470-630 Mpa. For plate thickness 100-150mm, the tensile strength of S235JR plates is 350-500 Mpa, S275JR plates is 400-540 Mpa, S355JR plates is 450-600 Mpa.
