ASTM A268 steel yeeb nkab
Qhov kev qhia tshwj xeeb no suav nrog ntau qib ntawm nominal-phab ntsa-thickness, stainless hlau tubing rau kev xeb-tiv taus thiab kev pabcuam kub.Feem ntau ntawm cov qib no feem ntau hu ua "ncaj-chromium" hom thiab yog tus yam ntxwv los ntawm kev ua ferromagnetic.Ob ntawm cov qib no, TP410 thiab UNS S 41500 (Table 1), yog amenable to hardening by heat treatment, and the high-chromium, ferritic alloys are sensitive to notch-brittleness on slow cooling to dog dig temperatures.Cov yam ntxwv no yuav tsum raug lees paub hauv kev siv cov ntaub ntawv no.Qib TP439 feem ntau yog siv rau kev pabcuam dej kub thiab tsis xav tau kev kho cua sov tom qab vuam los tiv thaiv kev tawm tsam ntawm thaj chaw tshav kub.
