P550 non-magnetic stainless steel rod introduction
P550 non-magnetic round steel cutting retail, P550 non-magnetic stainless steel rod processing custom, P550 non-magnetic stainless steel rod is a high nitrogen chromium manganese non-magnetic stainless steel rod, its chemical composition determines electromagnetic properties, stable organization, excellent mechanical properties, low permeability and high resistivity, eddy current loss in the magnetic field is minimal, At a magnetic field strength of 16,000 A /m (200 special hours),
The permeability of non-magnetic steel is μ≤1.319*10-6h/m(1.05 high/O). The permeability of stainless steel is μ=1.339*10-6h/m(1.1 high/O). Austenitic stainless steel has mild magnetism after cold working
P550 is a kind of high nitrogen chromium manganese non-magnetic stainless steel, its chemical composition determines the electromagnetic properties, stable organization, excellent mechanical properties, low permeability and high resistivity, eddy current loss in the magnetic field is very small, at the magnetic field strength of 16000a/m (200 special hours). The permeability of non-magnetic steel is μ≤1.319*10-6h/m(1.05 high/O). The permeability of stainless steel is μ=1.339*10-6h/m(1.1 high/O). Austenitic stainless steel has mild magnetism after cold working. In this state, non-magnetic steel can maintain stable austenite, with low permeability, high hardness, high density, good wear resistance. Due to the cold hardening of high manganese steel, it is difficult to cut, but the high temperature annealing process can change the particle size, shape and distribution of carbide to improve its cutting performance. Then the gas soft oxidation process is used to further improve the surface hardness, increase wear resistance, and improve the service life of the parts manufactured by the product.
P550 non-magnetic stainless steel is one of the most important and commonly used materials in the petroleum drilling field. It is usually used to produce:
Non-Magnetic Drill Collars, non-magnetic Drill collars,
The Collar for measuring while drilling/logging while drilling (MWD/LWD Collar),
Rotary Steerable Drilling,
Stabilizer and other products.
Because the domestic design of this type of steel did not take too much into account the corrosion resistance, coupled with the increasingly harsh environment of modern oil drilling (high temperature and high pressure high corrosion, etc.), the domestic non-magnetic stainless steel gradually exposed the shortcomings in the application.
Now more and more oil field equipment began to use imported non-magnetic stainless steel, imported non-magnetic stainless steel good performance to protect the electronic components in the equipment, greatly reducing the frequency of equipment maintenance and replacement and reduce the cost of maintenance.
Now recognized by the world foreign non-magnetic stainless steel manufacturers and product row number are:
15-15HS Max (Carpenter USA)
NMS140 (Jorgensen, USA)
P550 (P530,P750) (Austria SBS)
DATALLOY 2 (ATI)
