Abstract
One-inch plate obtained from a reference heat of type 304 stainless steel was characterized at room temperature. This characterization consisted of composition, microstructure, and mechanical property evaluations relative to data available for other heat of type 304 stainless steel. The influence of laboratory reannealing was also examined. The composition was fairly typical except for below average carbon and nitrogen levels. The microstructure was fairly free of inclusions, and the grain size was coarse. The yield strength was near the 30,000 psi minimum specified for type 304 stainless steel conforming to ASTM specification A 240 and below the minimum in the rearmealed condition. Possibly this was due to the coarse grain size in combination with low interstitial element content. Little, if any, differences were observed between specimens reannealed in the 1800 to 2000 deg F range. (auth)Keywords
