Powder Metallurgy Stainless Steel Manufacturer of custom

Short Description:

Powder metallurgy stainless steel can be made into parts.The stainless steel water smelted in the induction furnace flows out of the leakage hole of the nozzle, atomizes with high-pressure water, and condenses to get the stainless steel powder.The powder was dehydrated, dried, graded and annealed, and the bulk density of water atomized stainless steel powder was 2.5~3.2g/cm.It is formed under the pressure of 550~830MPa.The compaction is sintered in hydrogen or decomposed ammonia atmosphere with a dew point of -45~-50℃.Vacuum sintering can also be used, sintering temperature of 1120~1150℃.When good mechanical properties and corrosion resistance are required, sintering temperatures of up to 1315C are used.

Powder Metallurgy Stainless Steel

Powder Metallurgy Stainless SteelPowder 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.
