In special applications, ordinary bearing steel can't meet the demand, can choose according to different working conditions of the corresponding type stainless steel bearing, in order to cater to all kinds of special conditions of use, our company committed to the development and production of stainless steel bearings, main use material AISI SUS304, AISI SUS316, AISI SUS316L, AISI SUS440C, AISI SUS440B, etc.
The martensitic stainless steel AISI SUS440C as our standard material of stainless steel bearings, applicable to medium speed and high load.
As a special order, also provide austenitic stainless steel bearing (
304 or 316316 L)
Due to its hardenability, reason is only applicable to low speed and light load situations.
Austenitic stainless steel has no rust and corrosion resistance.
With increasing amount of Cr, nitric acid oxidation, such as acid corrosion resistance and high temperature oxidation resistance, vulcanization performance improvement.
With improving Ni content, the resistance to chloride stress corrosion performance and the performance of reducing acid increased.
With the decreasing amount of C, or join a stabilizing element, steel intergranular corrosion resistant performance for improvement.
With the increase of the amount of Mo, steel reducing acid resistance and resistance to pitting corrosion, crevice corrosion performance increase.
In steel containing Cu, in particular, Mo, Cu composite, steel has been improved, the sulfate resistance of containing Si ~ 4%, fuming nitric acid corrosion resistance.
Reduce some impurity elements in steel C, Si, P, such as Ti content, can be used as nitric acid, urea level using stainless steel.
Mechanical and physical properties have strong -
Tough -
Good cooperation from the plastic, excellent low temperature toughness, can be used as low temperature steel.
With the decreasing of C content in steel, the strength of the steel are down a bit,
Low carbon steel than high carbon low average of 29.
4~49MPa)
With the increase of cold deformation, the strength of the steel, elastic steel containing N, increase the strength of steel.
Cr-
Austenitic stainless steel with Mn, Mn N join reinforcement, strength of Cr - relatively
High Ni austenitic steel by about 30%, and plastic, toughness is better.
This kind of steel is non-magnetic more, can be used as no magnetic steel.
Chromium martensitic stainless steel does not rust resistance, resistance to weak corrosion medium, with increased Cr content, the addition of Mo increased corrosion resistance, with the C content increased, the corrosion resistance decline, with the increase of hardness, resistance to hydrogen sulfide stress corrosion sensitivity enhancement.
Martensite chromium nickel stainless steel does not rust resistance, including Cr17 %, corrosion resistance and 18
8 similar or slightly lower.
Mechanical and physical properties of chromium martensitic stainless steel with C content increased, the strength of steel, hardness increased, up to RC60 above, the wear resistance of steel is good, but the toughness is poor.
Containing Mo, V, improve the strength of steel.
Steel is strong - containing a small amount of Ni
Toughness cooperate well.
This kind of steel is brittle transition temperature, magnetic, small density, good shock resistance, elastic modulus was slightly lower than that of carbon steel.
Martensite chromium nickel stainless steel with high strength (
ó
S not less than 9800 mpa)
And high hardness (
RC is not less than 36)
With high strength/weight ratio.
When selecting a different material of stainless steel bearing should consider their own situation and application of the machine, select the most appropriate materials, experts around you professional stainless steel bearing.
