In this study, tensile behavior of Nb-containing 25Cr–20Ni austenitic stainless steels composed of coarse or fine grains has been investigated at temperatures ranging from room temperature to 900 °C. Results show that the tensile strength of fine-grained specimens decreases faster than that of coarse-grained specimens, as the test temperature increases from 600 °C to 800 °C. The rapidly ...

Control of grain size is the key to a successful ultrasonic test. An average grain size of 6 or finer is required for most stainless alloys. For light walls, around 0.015 in. thick, grain size 7 or finer is the target. A mix of large and small grains poses problems by creating noise.

Step 2: Preparing Stainless Steel Sheet. If you have a wider area to polish, you will realize that the grinder is digging deep into the surface. For stainless steel, you may need a 3-inch dual action air sander or an electric sander. Start with the coarsest 60-grit abrasive and proceed using finer versions 180-grit, 320-grit, and lastly 400-grit.

Because the deoxidation and grain refinement create hard abrasive oxide and nitride particles, they machine and process differently than coarse grained steels. Fine Austenitic Grain Size appears on the material test report as an ASTM value of 5 or greater.

(2) Cast steel slabs In the melting and deoxidizing operations of cast steel, some elements that delay grain growth are added. Therefore, compared with forged steel, cast steel is less likely to form coarse grains. Steel castings with coarse grains due to composition can be refined by annealing or normalizing.

with decreasing grain size. Machinability is also affected; rough machining favors coarse grain size while finish machining favors fine grain size. The effect of grain size is greatest on properties that are related to the early stages of deforma-tion. Thus, for example, yield stress is more dependent on grain size than ten-sile strength [2, 3].
