Notes
- Stainless round bar (304, also 316 and 303 at other distributors) comes in inch diameters in 1/16 to 1/8 in steps below 2 in and larger steps above. Metals Depot lists 33 diameters from 1/8 to 12 in for 304 (10 and 12 in as 304/304L); Remington Industries lists 8 round rod diameters (1/4 to 2 in in 1/4 in steps), every one of which is also on the Metals Depot list. Shaw Stainless & Alloy's page gives only a range, 1/8 to 20 in, in 303 / 304 / 316 / 17-4PH.
- Weights are Metals Depot's printed lb/ft, shown from 1/2 in up, where each agrees within 4 % with a density of 7.9 g/cm³ (304) computed from the diameter (a sanity check, not additional data). Below 1/2 in the printed values (1/8: 0.05, 3/16: 0.11, 1/4: 0.18, 5/16: 0.29, 3/8: 0.42, 7/16: 0.57) are 7 to 19 % above that computed value, so they are not used. 316 round bar was not listed on the pages read, so no 316 sizes are claimed.
- Flat bar: Remington's configurator options are thickness 1/4, 1/2 and 1 in, width 1/2, 1, 2, 3 and 4 in (which of these combinations are stocked is not stated, so no size table is claimed). Shaw's stainless flat bar range is thickness 1/8 to 3 in and width 1/2 to 8 in, grades 303 / 304 / 316 / 17-4PH. A distributor's complete flat bar list (thickness × width) was not read.
- Sheet and plate: the existing sheet-metal gauge page covers 10 to 20 gauge stainless sheet; stainless plate sizes were not read. No STEP/STL: bar stock is a plain cylinder or box.
