Hi Anshu, Here is what I have for 1010 steel. units are in um/mK. Stated values represents average coeffieient over temperature range. (from 0 to 100 c) 12.2 (from 0 to 200 c) 13.0 (from 0 to 300 c) 13.5 (from 0 to 400 c) 13.9 (from 0 to 500 c) 14.3 (from 0 to 600 c) 14.7 (from 0 to 700 c) 15.0 anshu mehtaon 04/12/2002 12:17:55 PM Please respond to mems-talk@memsnet.org To: mems-talk@memsnet.org cc: (bcc: Scott Sullivan/Disco_Corp) Subject: [mems-talk] metal properties Hi I am looking for the physical property of an alloy. I contacted the suppiers as well as a metallurgy worksop for this, even ASTM, but they couldnt provide me with the data. I am looking for the thermal expansion of coefficient for CRS 1010 the other specifications are: STANDARD SPECIFICATIONS: ASTM A109, AMS 5040, QQS 698 TYPICAL ANALYSIS: C .13 max Mn .30/.60 P .020 max S .025 Max TYPICAL HARDNESS: Rockwell B 65 max TYPICAL APPLICATIONS: Base plates, brackets, stampings, & washers AVAILABLE FORMS: Stock size sheets & coils. Material may also be Slit, Sheared, Laser Cut, Blanked, Edged, Deburred, and/or Reflattened to your specifications. Please get back to me with any information that you might have about this or even if you could suggest where I could look for this data, it would be of help. anshu Yahoo!
