Usually, we refer the steel pipe used at -10 ~ -196\u2103 as low temperature steel and below -196\u2103 as cryogenic steel pipe or ultra-low temperature steel pipe. It is generally believed that manganese, nickel and other elements can improve the toughness at low temperature. Experiments showed that with the increase of nickel content by 1%, the critical transition temperature of brittleness can be reduced by about 20\u2103.<\/p>\n<p>\uacb0\uc815 \uaca9\uc790 \uad6c\uc870\uc5d0 \ub530\ub77c, <a href=\"https:\/\/www.wldsteel.com\/ko\/product\/astm-a333-334-grade-3-steel-pipe\/\">\uc800\uc628 \uac15\uad00<\/a> \ubab8\uccb4 \uc911\uc2ec\uc758 \uc785\ubc29 \ud398\ub77c\uc774\ud2b8 \uc800\uc628 \uac15\ucca0\uacfc \uc5bc\uad74 \uc911\uc2ec\uc758 \uc785\ubc29 \uc624\uc2a4\ud14c\ub098\uc774\ud2b8 \uc800\uc628 \uac15\ucca0\ub85c \ub098\ub20c \uc218 \uc788\uc2b5\ub2c8\ub2e4. \uc800\uc628\uc758 \ud398\ub77c\uc774\ud2b8 \uac15\uc740 \uc628\ub3c4\uac00 \uc784\uacc4 \uac12 (\ub610\ub294 \ubc94\uc704)\uc73c\ub85c \uae09\uaca9\ud788 \uac10\uc18c\ud558\uba74 \ucde8\uc131 \uc804\uc774 \uc628\ub3c4\uc5d0 \ub300\ud55c \uba85\ubc31\ud55c \uc5f0\uc131\uc774\uba70 \uc778\uc131\uc774 \uac11\uc790\uae30 \uac10\uc18c\ud558\ubbc0\ub85c \uac15\uad00\uc740 \uac04\uc9c8 \ubd88\uc21c\ubb3c\uc744 \uc904\uc774\uace0, \uc785\uc790 \ud06c\uae30\ub97c \uc815\uc81c\ud558\uace0, \uac15\ucca0\uc758 2 \uc0c1 \ud06c\uae30, \ubaa8\uc591 \ubc0f \ubd84\ud3ec\ub97c \uc81c\uc5b4\ud558\ub294 \ub4f1\uc758 \ud569\uae08 \uc6d0\uc18c\ub97c \ucd94\uac00\ud558\uc5ec \uc804\uc774 \uc628\ub3c4 \uc774\ud558\ub85c \uc0ac\uc6a9\ud574\uc11c\ub294 \uc548\ub418\uba70, \ucde8\uc131 \uc804\uc774 \uc628\ub3c4\uc5d0 \ub300\ud55c \ud398\ub77c\uc774\ud2b8 \uc5f0\uc131\uc744 \uac10\uc18c\uc2dc\ud0b5\ub2c8\ub2e4 (\uae08\uc18d \ubcf4\uac15 \ucc38\uc870).<\/p>\n<p>\uc800\uc628 \uac15\uad00\uc740 \uc800\uc628\uc5d0\uc11c \uac15\ub3c4\uc640 \uc778\uc131\uc774 \uc6b0\uc218\ud558\uace0 \uac00\uacf5 \uc131\ub2a5\uacfc \ub0b4\uc2dd\uc131 \ub4f1\uc774 \uc6b0\uc218\ud569\ub2c8\ub2e4. \uc624\uc2a4\ud14c\ub098\uc774\ud2b8 \uc800\uc628 \ud30c\uc774\ud504\uc758 \uc800\uc628 \ubc94\uc704\uc5d0\ub294 \ucde8\uc131 \uc804\uc774 \uc628\ub3c4\uac00 \uc5c6\uc73c\uba70, \uc800\uc628 \ucda9\uaca9 \uc778\uc131\uc744 \uac80\uc99d\ud558\uc9c0 \uc54a\uace0 \uc77c\ubc18\uc801\uc73c\ub85c \uc0ac\uc6a9\ud560 \uc218 \uc788\uc2b5\ub2c8\ub2e4. \ud398\ub77c\uc774\ud2b8\uacc4 \uc800\uc628 \uac15\uc740 \uac00\uc7a5 \uc77c\ubc18\uc801\uc73c\ub85c \uc0ac\uc6a9\ub418\ub294 \ud30c\uc774\ud504 \uc18c\uc7ac\uc785\ub2c8\ub2e4. \uc5f4\ucc98\ub9ac \uacf5\uc815\uc740 \uc800\uc628 \uac15\ucca0\uc758 \ubbf8\uc138 \uad6c\uc870\uc640 \uc785\uc790 \ud06c\uae30, \ud2b9\ud788 \ub2f4\uae08\uc9c8 \ubc0f \ud15c\ud37c\ub9c1 \ud6c4 \ubd84\uba85\ud788 \uac1c\uc120\ub418\ub294 \uc800\uc628 \uc778\uc131\uc5d0 \uc601\ud5a5\uc744 \ubbf8\uce69\ub2c8\ub2e4. \uadf8\uac83\uc740 \uad6c\uc131\uc5d0 \ub530\ub77c \ub098\ub269\ub2c8\ub2e4:<\/p>\n<h3>\uc800\ud0c4\uc18c Mn\uac15<\/h3>\n<p>0.05 ~ 0.28% C\uc640 0.6 ~ 2%Mn\uc774 \ud568\uc720\ub418\uc5b4 \uc788\uc2b5\ub2c8\ub2e4.
