ASME SA387 GR.22 CL2 ji esi mmiri ọkụ na Pressure Vessel Steel efere

SA 387 GR.22 CL.2 Efere na-enwe chromium nke 2.25% na molybdenum nke 1% na ike na-arụ ọrụ na 600 Deg C okpomọkụ gburugburu n'ụzọ dị irè. Molybdenum na chromium ígwè efere na-arụ ọrụ nke ọma na okpomọkụ dị iche iche na-enye ọrụ kacha mma. Mgbakwunye nke molybdenum na SA 387 alloy na-abawanye ike ike nke efere na okpomọkụ ka ukwuu. Ọzọkwa, ọ na-enye ezigbo ikike nguzogide corrosion na oxidation yana site n'ịbawanye eriri lattice. Nke a na-akwụsị n'ụzọ dị irè onye na-emebi emebi site na mgbaze ígwè ma na-enye ikike nguzogide okpomọkụ dị mma ma ghọọ ezigbo nhọrọ maka gas gbara ya gburugburu. Ọzọkwa, ọ nwere ezigbo weldability. Ya mere, a na-achọ efere a nke ukwuu n'ụwa nile.
