Category: AISI & UNS Grades-Compositions & Properties

  1. Chemical compositions of ACI stainless and heat resisting steel castings grades

    ASTM standards A297, A351, A743, A744 and A890 specify castings for corrosion and heat-resisting service. These include stainless steels and some nickel based alloys. The grade designations used in these standards are those originally developed by the ACI, the Alloy Casting Institute. (Now the Steel Founder’s Society of America). The chemical composition of stainless steel grades covered by these standards include ACI grade designations CA6N, CA6NM, CA15, CA15M, CA28MWV, CA40, CA40F, CB6, CB30, CB7Cu-1, CB7Cu-2, CC50, CD3MCuN, CD3MN, CD3MWCuN, CD4MCu, CD6MN, CE20N, CE3MN, CE30, CE8MN, CF3, CF8, CF8C, CF20, CF3M, CF3MN, CF8M, CF8C, CF10, CF10M, CF10MC, CF10SMnN, CF16F, CF16FA, CG6MMN, CG3M, CG8M, CG12, CH8, CH10, CH20, CK20, CK3MCuN, CK35MN, CN3M, CN3MN, CN7M, CN7MSCT15C, HC, HD, HE, HF, HH, HI, HK, HK30, HK40, HL, HN, HP, HT, HT30, HU, HW, HX. Duplex castings grades 1A, 1B, 1C, 2A, 3A, 4A, 5A, 6A are also listed and cross references to wrought AISI grades 410, 420, 304L, 304, 347, 302, 316L, 316LN, 316, 317, 317L, 309, 310 made.

  2. Chemical compositions of AISI (ASTM/ASME) and UNS austenitic stainless steel grades

    Most ASTM and ASME standards list the steel grades by their UNS, (Unified Numbering system), numbers but also make reference, where appropriate to the more general AISI, (American Iron and Steel Institute), grade designations. These grade numbering systems are widely used in the USA, where they originated and are recognised by most stainless steel specifiers and users. In Japan the AISI grade number is preceded by SUS, e.g. SUS 304. The chemical compositions of stainless steel grades covered in this article include AISI / common grade names, 301, 301L, 301LN, 302, 302B, 303, XM-5, 303Plus X 303Se, 303Cu, 304, 304L, 302HQ, XM-21, 304HN, 304LN, 305, 308, 316, 316L, 316Ti, 316Cb316LN, 317, 317L, 317LM, 317LMN, 317LN, 321, 347, 347F, 347FSe, 348, 384, 201, Gall-Tough, 202, XM-1, 203EZ, 205, XM-19, Nitronic 50, XM-31, Tenelon, XM-14, XM-17, 216, XM-18, 216L, Nitronic 60, 21-6-9, Nitronic 40, XM-11, XM-29, Nitronic 33, 18-2Mn, Nitronic 32, 18-18 Plus, 20Cb-3, 20Mo-4, 20Mo6, Sanicro28, AL-6X, AL-6XN, JS700, 904L, 1925hMo, Cronifer, 1815, LCSi, 310MoLN, 254SMO, 654SMO, Nirosta, 4565S, XM-15, 18-8-2, SAE grades, 30301, 30302, 30302B, 30303, 30303Se, 30304, 30304L, 30305, 30308, 30316, 30316L, 30317, 30321, 30347, 30348, 30384, 30201, 30202, and UNS grades S30100, S30103, S30153, S30200, S30215, S30300, S30310, S30323, S30330, S30400, S30403, S30430, S30452, S30453, S30454, S30500, S30800, S31600, S31603, S31635, S31640, S31653, S31700, S31703, S31725, S31726, S31753, S32100, S34700, S34720, S34723, S34800, S38400, S20100, S20103, S20153, S20161, S20162, S20200, S20300, S20400, S20500, S20910, S21400, S21460, S21600, S21603, S21800, S21900, S21904, S24000, S24100, S28200, N08020, N08024, N08026, N08028, N08366, N08367, N08700, N08904, N08925, N08926, S30600, S30601, S31050, S31254, S31266, S31277, S32050, S32615, S32654, S34565, S35135, S38100, S38815.
