    摘要: This invention provides a non-magnetic, austenitic, corrosion resistant stainless steel alloy having improved machinability, a consistently reproduceable coefficient of thermal expansion, and an essentially ferrite-free structure. The alloy contains about 0.04-0.10 w/o C, 0.03-0.07 w/o N, 2.00 w/o max. Mn, 1.00 w/o max, Si, 0.045 w/o max. P, 0.015-0.10 S, 19.00-24.00 Cr, 0.75 w/o max. Mo, 12.00-18.00 w/o Ni, and the balance iron. The alloy is balanced so that no more than about 2 v/o ferrite as determined by the DeLong diagram is present and so that the coefficient of thermal expansion is about 14.5.times.10.sup.-6 to 16.5.times.10.sup.-6 per C..degree. within the temperature range of about -51 to 121 C.This invention further provides articles, including a non-magnetic tube in a magnetically biased accelerometer having good corrosion resistance, a coefficient of thermal expansion of about 14.5.times.10.sup.-6 to 16.5.times.10.sup.-6 per C..degree. within the temperature range of about -51 to 121 C., and containing no more than about 2 v/o ferrite as determined by the DeLong diagram and therefore, being non-magnetic.
