2.2 Materials The Materials listed in the following sectious are suggcsted for usC based on their ability to meet the physical, mechanical, chemical, and environmental re- quirements of a given application. Acceplance of a material for a specifie application must be based on service experience or independent venification of its suitabilhty , 2.2.1 General Considerations (a) Materials slhall conforn 10 the applicable rcquite- ments in the sections herceinafier detailed. (b) The contractor shall subomit one copy of the chemical composition and mcchanical-property mill tcst reports for all steels used to the owner for pproval prior to construction unless otherw ise indicated. (e) When required for tssing purposes, the contractor will furnish the owner with identifed scrap samples of the shell plates. (d) This secton does not apply to linings and Catings of stacks. See Section 3. (e) Corrosion allowances shall be considered (typi- cally /i6 in. 10 % in.) where carbon, high- strengh. low alloy. and ulloy steels are used. Experience or the results of tcsts should be used when sclccling an allowance. 2.2.2 Shell and Base Plates. For more informa- tion on this subject. see Tables B-I through B-11 in Nunandatory Appendix B. (a) Shell and base plates typically may be of one or more of the following structural quality materials: (1) Carbon sieels confouming 10 the ASTM A 36, A 283, or A 529 Spcifications, (2) High-strength, low lly seels conforming to the ASTM A 242. A 572, or A 588 Speeifications; (3) Stainless steels conforming to the ASTM A 666 Specifcation; (4) Stainless chromium- nickel steel clad plate con forming to ASTM A 264 and nickel-base alloy clad steel conforming to ASTM A 265 may be considered for use as shell plate: (5) Metals listed in Materials Appendix (ie, Non- mandatury Appendix B). Table B-9 may be used not only as sheel linings and cladding but also as solid plate for shell plates. (6) Pressure vessel quality carbon steeis such as ASTM A 285. A 515, and A 516, llay sleels such as ASTM A 387; and stain (c) Carbon Steels such as ASTM A 516. Grades 55 through 70 and low alloy steels such as ASTM A 517. Grades A through T and ASTM A 537 are usually specifed for service temperatures as low as – -50^F (- 46°C). Nickel-containing alloy steels such as ASTM A 203, Grades A and B are usually used for service temperatures as low as -75°F (- 59°C); and ASTM Grades D, E, and F are often used for service tempera- tures of -150 (-101°C) Nickel-containing alloy steels and nickel stainless steels are used for even lower temperatures. Suppliers of structural quality steels will provide data on notch toughness when specified. (d) Prolection against corrosion and/or oxidation may be required on interior and/or exterior surfaces de- pending on the malerials utilized and the conditions encountered. Section 3 should be consulted and utilized as appropriate. (e) Creep rupture tensile stresses for sustained load- ing and high temperature service conditions must be considered as given in para. 4.4.8. 2.2.3 tiffeners and Structural Braces and/or Framework (a) Stifteners and structural braces and/or framework typically may be of one or more of the following matcrials: (I) Carbon steels conforming to the ASTM A 36, A 283, or A 529 Specifications; (2) High-strength, low alloy stcels conforming to the ASTM A 242. A 572, or A 588 Spcificatiuns; (3) Stainless sicels conforming to the ASTM A 240 or A 666 Specifications or nickel-containing alloys having compositions similar to those of the shell plate. (b) Protection may be required against corrosion for components exterior to the shell and against corrosion and/or oxidation for components on the shell interior. Section 3 should he consulted and utilized as appro- priate.ASME STS-1 pdf download.
