When a pass heats the surface faster than the bulk can absorb, the surface either re-hardens into a brittle white layer at 65 to 70 HRC or softens due to local tempering, and the resulting thermal stress opens fine cracks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\uc774\ub7ec\ud55c \ubbf8\uc138 \uade0\uc5f4\uc740 \ub208\uc5d0 \uc798 \ub744\uc9c0 \uc54a\uc9c0\ub9cc, \uacfc\ub3c4\ud55c \uc5f0\uc0ad \uc791\uc5c5\uc73c\ub85c \uc778\ud574 \uae4a\uc5b4\uc9c0\uace0 \ud53c\ub85c \ud30c\uad34\uc758 \uc8fc\uc694 \uc6d0\uc778\uc774 \ub429\ub2c8\ub2e4. \uc801\uc808\ud55c \uc5f0\uc0ad \ud720 \uc120\ud0dd, \uc81c\uc5b4\ub41c \uc18d\ub3c4, \uadf8\ub9ac\uace0 \ucda9\ubd84\ud558\uace0 \ud6a8\uacfc\uc801\uc778 \ub0c9\uac01\uc218 \uacf5\uae09\uc740 \uc774\ub7ec\ud55c \uc190\uc0c1\uc744 \ubc29\uc9c0\ud569\ub2c8\ub2e4. \uc5f0\uc0ad \uc791\uc5c5\uc740 \uac89\ubcf4\uae30\uc5d0\ub294 \uba40\uca61\ud574 \ubcf4\uc774\ub294 \uae08\ud615\uc774\ub77c\ub3c4 \uc870\uc6a9\ud788 \uc190\uc0c1\uc2dc\ud0ac \uc218 \uc788\ub294 \ub9c8\ubb34\ub9ac \ub2e8\uacc4\uc774\ubbc0\ub85c \uc8fc\uc758\ud574\uc57c \ud569\ub2c8\ub2e4.<\/p>\n\n\n\n<h2 id=\"h-what-goes-wrong-during-h13-heat-treatment\" class=\"wp-block-heading\">H13 \uc5f4\ucc98\ub9ac \uacfc\uc815\uc5d0\uc11c \ubb34\uc5c7\uc774 \uc798\ubabb\ub418\ub098\uc694?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">H13 \uae08\ud615\uc758 \ud488\uc9c8\uc774 \uacb0\uc815\ub418\ub294 \uac00\uc7a5 \ud070 \uc694\uc778\uc740 \uc5f4\ucc98\ub9ac \uacfc\uc815\uc785\ub2c8\ub2e4. \uc8fc\uc694 \ubb38\uc81c\uc810\uc73c\ub85c\ub294 \ud0c8\ud0c4, \ubcc0\ud615, \uade0\uc5f4, \uc794\ub958 \uc624\uc2a4\ud14c\ub098\uc774\ud2b8\uac00 \uc788\uc73c\uba70, \uac01\uac01\uc758 \ubb38\uc81c\ub294 \ub300\uae30 \uc870\uac74 \ubc0f \uac00\uc5f4 \ub610\ub294 \ub0c9\uac01 \uc18d\ub3c4\uc640 \uad00\ub828\uc774 \uc788\uc2b5\ub2c8\ub2e4.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Decarburization strips carbon from the surface in poorly controlled furnaces and leaves a soft skin, so it hardens in vacuum, neutral salt, or controlled neutral atmospheres. Distortion and cracking come from uneven heating or quenching, especially in complex sections, and staged preheat with controlled air quenching reduces the gradients. Retained austenite, common in higher-alloy H13, is soft and unstable, and can later transform, embrittling the material. Tempering at 540 to 620\u00b0C for two or three cycles, sometimes with sub-zero treatment, transforms and stabilizes it.<\/p>\n\n\n\n<h2 id=\"h-what-are-the-most-common-h13-failure-modes-in-service\" class=\"wp-block-heading\">H13 \uae30\uc885\uc5d0\uc11c \uac00\uc7a5 \ud754\ud558\uac8c \ubc1c\uc0dd\ud558\ub294 \uace0\uc7a5 \uc720\ud615\uc740 \ubb34\uc5c7\uc785\ub2c8\uae4c?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\uc0ac\uc6a9 \uc911 \ubc1c\uc0dd\ud558\ub294 \uc8fc\uc694 \uace0\uc7a5\uc740 \uc5f4\ud53c\ub85c, \uc2ec\uac01\ud55c \uade0\uc5f4 \ubc0f \ub9c8\ubaa8\uc785\ub2c8\ub2e4. \uc5f4\ud53c\ub85c, \ub610\ub294 \uc5f4 \uade0\uc5f4\uc740 \uace0\uc628 \uac00\uacf5 \uae08\ud615\uc5d0\uc11c \uac00\uc7a5 \ud754\ud558\uac8c \ubc1c\uc0dd\ud569\ub2c8\ub2e4. \ubc18\ubcf5\uc801\uc778 \uac00\uc5f4 \ubc0f \ub0c9\uac01 \uc0ac\uc774\ud074\ub85c \uc778\ud574 \ud45c\uba74\uc5d0 \ubbf8\uc138\ud55c \uade0\uc5f4\ub9dd\uc774 \ud615\uc131\ub418\uace0, \ub2e4\uc774\uce90\uc2a4\ud305 \uacf5\uc815\uc5d0\uc11c \uc6a9\uc735 \uc54c\ub8e8\ubbf8\ub284\uc774 \uc555\ub825 \ud558\uc5d0 \uc774\ub7ec\ud55c \uade0\uc5f4 \uc18d\uc73c\ub85c \uc720\uc785\ub418\uba74 \ubd80\ud488 \ucd94\ucd9c \ubc0f \ud45c\uba74 \ud488\uc9c8\uc774 \uc800\ud558\ub429\ub2c8\ub2e4.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\uac70\ub300 \uade0\uc5f4\uc740 \uc791\uc740 \ubc18\uacbd\uacfc \uac19\uc740 \uc751\ub825 \uc9d1\uc911 \ubd80\uc704\uc5d0\uc11c \uae30\uacc4\uc801 \uc751\ub825\uacfc \uc5f4\uc801 \uc751\ub825\uc774 \ubcf5\ud569\uc801\uc73c\ub85c \uc791\uc6a9\ud558\uc5ec \ubc1c\uc0dd\ud558\ub294 \ud06c\uace0 \uae4a\uc740 \ud30c\uc190\uc774\uba70, \uc870\ub300 \uacb0\uc815\ub9bd, \ud0c4\ud654\ubb3c \ud3b8\uc11d \ub610\ub294 \uacfc\uc789 \uc794\ub958 \uc624\uc2a4\ud14c\ub098\uc774\ud2b8\uc640 \uac19\uc740 \uacb0\ud568\uc5d0 \uc758\ud574 \uc545\ud654\ub418\ub294 \uacbd\uc6b0\uac00 \ub9ce\uc2b5\ub2c8\ub2e4. \ub2e8\uc870 \uacf5\uc815\uc5d0\uc11c \ub9c8\ubaa8\ub294 \uc8fc\uc694 \uc6d0\uc778\uc774\uba70, \uc2a4\ucf00\uc77c \ubc0f \uacbd\uc9c8 \uc785\uc790\uc5d0 \uc758\ud55c \ub9c8\ubaa8\uc640 \uace0\uc628\uc5d0\uc11c\uc758 \uc811\ucc29\uc131 \uae01\ud798\uc73c\ub85c \uc778\ud574 \uae08\ud615 \ud30c\uc190\uc758 \uc57d 70%\ub97c \ucc28\uc9c0\ud569\ub2c8\ub2e4.<\/p>\n\n\n\n<h2 id=\"h-when-should-you-not-use-h13\" class=\"wp-block-heading\">H13\uc744 \uc0ac\uc6a9\ud558\uba74 \uc548 \ub418\ub294 \uacbd\uc6b0\ub294 \uc5b8\uc81c\uc785\ub2c8\uae4c?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\ubd80\uc2dd\uc774 \uc2ec\ud55c \uc791\uc5c5, \ub9c8\ubaa8\uac00 \ub9e4\uc6b0 \uc2ec\ud55c \uc791\uc5c5 \ub610\ub294 H13\uc758 \uc5f0\ud654 \uc628\ub3c4 \ubc94\uc704\ub97c \ubc97\uc5b4\ub098\ub294 \uc0ac\uc6a9 \uc628\ub3c4\uc5d0\uc11c\ub294 \ub2e4\ub978 \ub4f1\uae09\uc744 \uc120\ud0dd\ud558\uc2ed\uc2dc\uc624.
