Technical data for Stainless steel bearings

Describtion of stainless material

      正在特种运用场所,一般轴承钢没法知足需求,可凭据差别工况挑选响应范例的不锈钢轴承,我公司常用去建造不锈钢轴承的质料有AISI SUS304AISI SUS316,AISI SUS316L,AISI SUS440C,AISI SUS440B等。个中马氏体不锈钢AISI SUS440C作为我司不锈钢轴承的尺度材质,适用于中等转速及较下负荷运用。作为稀奇定货,也供应奥氏体不锈钢轴承(304或316,316L),果其弗成淬硬性,故仅适用于低速及沉负荷场所运用。

Austenitic stainless stee
corrosion-resistance.
     All have rustless property and corrosion-resistance. Increase by with Cr amounts, it's able to bear hydrogen nitrate and oxidated acid corrosion and high temperature oxidated- resistance, enhance sulfuration capability. Increase by with Ni amounts, increase chloride- resistance stress corrosion capability and reductive acid- resistance. decrease by with C amounts,or adding steady element, the steel being able to bear corrodes a function among crystal improvement. Increase by with Mo amounts, steel's reductive-resistance and corrosion-resistance function increasing by. Contain Cu in steel, especially Mo、Cu compound,steel's sulfuric acid-resistance function having improving noticeably, when contain Si 4%,can be able to bear or endure aerosol nitric acid corrosion. Foreign substance element decrease a little steel,content such as C、Si、P、Ti, may be put into use as hydrogen nitrate level , urea level stainless steel.
Mechanics and physics function:
      All fine having the strong- tenacious- plasticity equally fits,low temperature tenacity is extremely nice, Can be put into use as low temperature steel. decrease by with C amounts with steel, the steel intensity is had a little of coming down(Generally low carbon steel is 29.4~49 MPa lower than tall carbon steel) Follow cold deformation amounts increasing by, the steel intensity, Elasticity is improved when containing N in steel, the steel intensity increases by. Cr-Mn Austenitic stainless steel since Mn , N put in strengthen an effect, the intensity is higher than Cr-Ni austenite steel approximately 30%, the plasticity、tenacity are still nice. This steel is nonmagnetic excessive, Therefore being able to be nonmagnetic steel be put into use.

Martensite stainless steel
corrosion-resistance:
      Martensite chromium stainless steel has rustless property, be able to bear weak medium corrosion, Increase by with Cr amounts, after Mo adds corrosion-resistance increase by, Increase by with C amounts, corrosion-resistance coming down, increase by with the hardness, Hydrogen sulfide- resistance stress corrosion sensitivity increases by. Martensite chromium nickel stainless steel has rustless property,when contain Cr17%, corrosion-resistance is as 18-8 or lower.
Mechanics and physics function:
      Martensite chromium stainless steel increase by with C amounts, steel intensity、hardness are raised. Maximal can reach above RC60, the steel abrasion resistance is good,but tenacity is bad.when contain Mo、V, the steel intensity is improved.When contain a little Ni, strong steel- tenacity fits well.This kind of steel has mbrittlemen peak temperature, magnetic,small density, concuss- resistance fine, the elasticity modulus is lower than carbon steel slightly.Martensite chromium nickel stainless steel has its high strength(ós is greater than 9800MPa)and high rigidity(RC is greater than 36), have higher intensity/ weight ratio.

Material hits the target in stainless steel bearing applying:
SUS304,SUS316,SUS316L:
      Austenitic stainless steel bearing’s inner outer ring、ball、cage、rivet、housing、bearing peak thread、dustproof seal、frame of the seal. Martensite stainless steel bearing’s cage、rivet、housing、bearing peak thread、dustproof seal、frame of the seal.
