Grade chemistry and mechanical properties supplied in monel pipe & fittings.
Chemical composition and mechanical properties are grade properties, not form properties — the same grade keeps the same chemistry whether it is supplied as sheet, plate or coil. The tables below list the specified limits for each grade we stock in monel pipe & fittings, tested and certified to ASTM B165. Values are weight percent (maximum unless a range is shown); mechanical values are minima in the annealed condition.
