Powder metallurgical stainless steel can be made into steel.The stainless steel water was atomized into powder with high pressure nitrogen. The powder particles were spherical, the density of loose packing was about 4.8g/cm, and the oxygen content of powder was less than 100×10.Ball stainless steel powder can also be produced by rotating electrode pulverization with oxygen content of (40~70)×10.These stainless steel powders are put into the casing, vacuum sealed, cold isostatic pressing at 5kPa pressure, and then hot isostatic pressing at 1050℃ and 2kPa pressure to densify the material.The cold isostatic compaction can also be hot extruded into compact rods and pipes at 1200℃.Compared with ordinary cast and forged stainless steel, the segregation of nickel, chromium and molybdenum elements in powder treated stainless steel is smaller, the grain size is much smaller, and the sulfide inclusion is fine and evenly distributed.So it's improved:

1. Stainless steel powder metallurgy parts

2. Stainless steel powder metallurgy parts

3. Mechanical properties and corrosion resistance.

Special stainless steels with high molybdenum, nickel, nitrogen and manganese content are used to enhance corrosion resistance and strength in harsh offshore environments.1234
