ASTM A743/A743M Corrosion-Resistant Castings
Scope of ASTM A743/A743M
ASTM A743/A743M is a material specification for corrosion-resistant iron-chromium and iron-chromium-nickel alloy castings intended for general applications. It is not a universal casting grade or a blanket suitability statement for every corrosive service. The purchase order must identify the required grade, unit system, drawing and any supplementary requirements.
Information needed for a casting enquiry
Provide the exact ASTM designation and edition, alloy grade, part drawing, dimensions, machining allowance, heat-treatment condition, quantity and target delivery state. Define required chemical analysis, tensile or hardness tests, nondestructive examination, pressure testing, repair restrictions, marking and certification. Service medium, temperature and design-code requirements remain the purchaser’s responsibility and should be included where they affect material selection.
