In a diaphragm valve designed to seal with a metal diaphragm, corrosion resistance and strength of the diaphragm are improved by forming the diaphragm from a thin alloy sheet containing, by weight, 12.5-14.5% Mo, 20.0-22.5% Cr, 2.0-6% Fe, 2.5-3.5% W, 2.5% or less Co, 0.015% or less C, 0.08% or less Si, 0.50% or less Mn, 0.35% or less V, 0.02% or less P, 0.02% or less S and the remainder Ni. The thin alloy sheet is cold-rolled after annealing to enhance the strength of the diaphragm.
