Low temperature performance of stainless steel welded pipe is shown below 1. Low temperature embrittlement  In low temperature environment, the deformation energy is small. In low temperature environ...

Notes of stainless steel pipe in the storage 1. First, the stainless steel pipe in the preservation of the time must be avoided and the corrosion of chemicals together, if the leakage will be on the ...

Electrolytic polishing principle is mainly: the metal ions on the workpiece and the phosphoric acid in the polishing solution to form a layer of phosphate film adsorbed on the surface of the workpiece...

Hot-rolled stainless steel seamless pipe processing technology, according to different production methods can be pided into hot-rolled tube, cold-rolled tube, cold drawn tube, extrusion pipe. 1, Hot-r...

The process of making stainless steel seamless pipe: 1, steelmaking → 2, rolling round steel → 3, perforation (annealing) → 4, cold drawn → 5, cold rolling (annealing, demagnetization, pickling, clean...

First, the magnetic test The magnetic test is the simplest way to distinguish between annealed austenitic stainless steel and ferritic stainless steel. Austenitic stainless steel is non-magnetic steel...

1. Plasticity: plasticity refers to the metal material under the action of the load, resulting in plastic deformation (permanent deformation) without breaking the ability. 2. Hardness: hardness is a ...

1, Argon arc welding. Stainless steel welded pipe requirements penetration penetration, no oxide inclusions, heat affected area as small as possible, tungsten inert gas protection of the TIG welding h...
