p235gh vs p265gh specification and model table

P235GH vs P265GH surface cracks refer to the linear cracks on the surface of p235gh vs p265gh, 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: p235gh vs p265gh surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.

ASTM A335 specification covers main grades of P11, P12, P22,P9 nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high-temperature service. Pipe and tube ordered to this specification shall be suitable for bending, flanging, and similar forming operations, and for fusion welding.

As we all know, steel pipes occupy more space in the process of transportation. If there is no good way of packing, the transportation cost for steel pipes will be a big expense. In view of this characteristic, our company is ingenious and adopts the nest package method to solve this problem perfectly. The premise of the nest package is that the diameters of the steel pipes are different, and the small diameter pipe is inserted in the large diameter pipe. This not only saves the volume, but also saves the transportation cost. It also reduces the loading and unloading workload by half, saves precious time, and enables customers to receive goods earlier.

Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of p235gh vs p265gh, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
