is a high-carbon, high-chromium cold-work tool steel used for blanking dies, forming tools,\n        shear blades, and other wear-resistant tooling. The same chromium carbides that give D2 its\n        excellent wear resistance and dimensional stability also make it one of the harder cold-work\n        steels to machine.\n      <\/p>\n      <p>\n        Equivalent grades include DIN 1.2379 and JIS SKD11. The practical machining guidance below\n        applies to D2, 1.2379, SKD11, and closely related D2-type cold work tool steels.\n      <\/p>\n    <\/header>\n\n    <article class=\"aobo-article\">\n      <p>\n        D2 should normally be rough-machined in the annealed condition before heat treatment. In this\n        condition it can be turned, milled, drilled, and ground with suitable carbide, cermet, or\n        high-quality tool materials, but cutting speeds must stay conservative because its chromium-rich\n        carbides cause rapid tool wear.\n      <\/p>\n      <p>\n        After hardening to about 58-60 HRC, conventional turning, milling, and drilling become much\n        more difficult. The work is usually finished by grinding, EDM, PCBN hard turning, or controlled\n        hard milling. The correct parameters depend on steel condition, tool material, machine rigidity,\n        coolant control, and required surface finish.\n      <\/p>\n\n      <h2>D2 \uacf5\uad6c\uac15\uc758 \uc8fc\uc694 \ub9e4\uac1c\ubcc0\uc218 \uc694\uc57d<\/h2>\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr>\n              <th>\uc791\uc5c5<\/th>\n              <th>\uc7ac\ub8cc \uc0c1\ud0dc<\/th>\n              <th>\uad8c\uc7a5 \ub3c4\uad6c \ub610\ub294 \ud504\ub85c\uc138\uc2a4<\/th>\n              <th>\uc2e4\uc6a9\uc801\uc778 \ucc38\uace0 \uc0ac\ud56d<\/th>\n            <\/tr>\n          <\/thead>\n          <tbody>\n            <tr><td>\uac70\uce5c \uc120\uc0ad<\/td><td>\uc5f4\ucc98\ub9ac \ud6c4, \uc57d 200-250 HB<\/td><td>\ucf54\ud305\ub41c \ucd08\uacbd<\/td><td>D2\ub294 \ub9c8\ubaa8\uc131\uc774 \uac15\ud558\ubbc0\ub85c \uc18d\ub3c4\ub97c \uc81c\ud55c\uc801\uc73c\ub85c \uc0ac\uc6a9\ud558\uc2ed\uc2dc\uc624.<\/td><\/tr>\n            <tr><td>\ub9c8\ubb34\ub9ac \uc791\uc5c5<\/td><td>\uc5b4\ub2d0\ub9c1\ub41c<\/td><td>\ucf54\ud305\ub41c \ucd08\uacbd\ud569\uae08 \ub610\ub294 \uc138\ub77c\ubbf9<\/td><td>\uc138\ub77c\ubbf9 \uace8\uc7ac\ub294 \ub354 \ube60\ub978 \uc18d\ub3c4\ub85c \uc791\ub3d9\ud560 \uc218 \uc788\uc9c0\ub9cc, \uc548\uc815\uc801\uc778 \ud658\uacbd\uc5d0\uc11c\ub9cc \uac00\ub2a5\ud569\ub2c8\ub2e4.<\/td><\/tr>\n            <tr><td>\uae09\ud68c\uc804<\/td><td>\uacbd\ud654 \uacbd\ub3c4 \uc57d 58-60 HRC<\/td><td>PCBN \ub610\ub294 \uc138\ub77c\ubbf9<\/td><td>\uc8fc\ub85c \ub9c8\ubb34\ub9ac \uc791\uc5c5\uc5d0 \uc0ac\uc6a9\ub418\uba70, \ub300\ub7c9\uc758 \uc7ac\ub8cc\ub97c \uc81c\uac70\ud558\ub294 \ub370\ub294 \uc801\ud569\ud558\uc9c0 \uc54a\uc2b5\ub2c8\ub2e4.<\/td><\/tr>\n            <tr><td>\uac08\uae30<\/td><td>\uc5b4\ub2d0\ub9c1\uc774 \uc120\ud638\ub428<\/td><td>\ucf54\ud305\ub41c \ucd08\uacbd\ud569\uae08 \ub610\ub294 \uace0\ud488\uc9c8 \uace0\uc18d\ub3c4\uac15<\/td><td>\uacf5\uad6c \ub3cc\ucd9c\ubd80\ub97c \uc9e7\uac8c \uc720\uc9c0\ud558\uace0 \uc9c4\ub3d9\uc744 \ubc29\uc9c0\ud558\uc2ed\uc2dc\uc624.<\/td><\/tr>\n            <tr><td>\uacbd\uc9c8 \ubc00\ub9c1<\/td><td>\uacbd\ud654 \uacbd\ub3c4 \uc57d 58-60 HRC<\/td><td>\ucf54\ud305\ub41c \ud0c4\ud654\ubb3c \ub610\ub294 PCBN<\/td><td>\uacac\uace0\ud55c \uae30\uacc4\uc640 \uc548\uc815\uc801\uc778 \uacb0\ud569\uc774 \ud544\uc694\ud569\ub2c8\ub2e4.<\/td><\/tr>\n            <tr><td>\uad50\ub828<\/td><td>\uc5b4\ub2d0\ub9c1\uc774 \uc120\ud638\ub428<\/td><td>\ucf54\ubc1c\ud2b8 HSS \ub4dc\ub9b4, \ucd08\uacbd \ud301 \ub4dc\ub9b4 \ub610\ub294 \uc194\ub9ac\ub4dc \ucd08\uacbd \ub4dc\ub9b4<\/td><td>\uac00\ub2a5\ud558\uba74 \uacbd\ud654 \uc804\uc5d0 \ub4dc\ub9b4 \uc791\uc5c5\uc744 \ud558\uc2ed\uc2dc\uc624.<\/td><\/tr>\n            <tr><td>\uc5f0\ub9c8<\/td><td>\uc5b4\ub2d0\ub9c1 \ub610\ub294 \uacbd\ud654<\/td><td>\uae30\uc874 \ud720, SG \ud720 \ub610\ub294 CBN \ud720<\/td><td>\ud0c0\uac70\ub098 \uac08\ub77c\uc9c0\ub294 \uac83\uc744 \ubc29\uc9c0\ud558\uae30 \uc704\ud574 \uc5f4\uc744 \uc870\uc808\ud558\uc138\uc694.<\/td><\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n\n      <h2>D2 \uacf5\uad6c\uac15\uc740 \uc65c \uac00\uacf5\ud558\uae30 \uc5b4\ub824\uc6b8\uae4c\uc694?<\/h2>\n      <p>\n        D2 is widely recognized as difficult to machine compared with conventional steels. Its high\n        carbon and chromium content forms hard chromium-rich carbides distributed through the steel\n        matrix. During cutting, these carbides behave like abrasive inclusions, accelerating tool wear\n        and increasing cutting forces.\n      <\/p>\n      <p>\n        A practical machinability rating for D2 is around 45 percent, compared with 100 percent for a\n        1 percent carbon water-hardening tool steel such as W1. In practice this means lower cutting\n        speeds, stronger cutting tools, rigid workholding, and careful heat control.\n      <\/p>\n      <p>\n        The steel condition has the biggest effect on parameter selection. Annealed D2 is much easier\n        to machine because its spheroidized carbides sit in a softer matrix. Hardened D2, normally\n        about 58-60 HRC in cold-work tooling, requires PCBN, ceramic tools, grinding, or EDM for\n        final finishing. For this reason, most stock removal should be completed before heat treatment,\n        and post-hardening machining should be limited to final dimensional correction and surface\n        finishing.

Successful weld repair usually depends\n        on controlled preheating, a suitable filler material, slow cooling after welding, and a post-weld\n        temper.\n      <\/p>\n\n      <h2>\uad8c\uc7a5 \uac00\uacf5 \uc21c\uc11c<\/h2>\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr><th>\ub2e8\uacc4<\/th><th>\uad8c\uc7a5 \uc791\ub3d9 \ubc29\uc2dd<\/th><th>\ubaa9\uc801<\/th><\/tr>\n          <\/thead>\n          <tbody>\n            <tr><td>\uc6d0\ub8cc \uc900\ube44<\/td><td>\uc2a4\ucf00\uc77c, \ud0c8\ud0c4\uce35 \ubc0f \uac70\uce5c \ud45c\uba74 \uacb0\ud568\uc744 \uc81c\uac70\ud569\ub2c8\ub2e4.<\/td><td>\uac00\uacf5 \uc77c\uad00\uc131 \ud5a5\uc0c1<\/td><\/tr>\n            <tr><td>\ud669\uc0ad \uac00\uacf5<\/td><td>\uc5b4\ub2d0\ub9c1 \ucc98\ub9ac\ub41c \uc0c1\ud0dc\uc758 \uae30\uacc4<\/td><td>\uacf5\uad6c \ub9c8\ubaa8\uac00 \uc801\uc740 \uc7ac\ub8cc\ub97c \ub300\ubd80\ubd84 \uc81c\uac70\ud558\uc2ed\uc2dc\uc624.<\/td><\/tr>\n            <tr><td>\uc2a4\ud2b8\ub808\uc2a4 \ud574\uc18c<\/td><td>\ud544\uc694\uc5d0 \ub530\ub77c \uac70\uce5c \uac00\uacf5 \ud6c4 \uc801\uc6a9\ud558\uc2ed\uc2dc\uc624.<\/td><td>\uacbd\ud654 \uacfc\uc815 \uc911 \ubcc0\ud615\uc744 \uc904\uc785\ub2c8\ub2e4<\/td><\/tr>\n            <tr><td>\ubc18\uac00\uacf5<\/td><td>\uc5f4\ucc98\ub9ac \uacfc\uc815\uc5d0\uc11c \ubc1c\uc0dd\ud560 \uc218 \uc788\ub294 \ubcc0\ud615\uc744 \uace0\ub824\ud558\uc5ec \uc801\uc808\ud55c \uc5ec\uc720 \uacf5\uac04\uc744 \ub0a8\uaca8\ub450\uc2ed\uc2dc\uc624.<\/td><td>\uacbd\ud654 \uc804\uc5d0 \ud615\uc0c1\uc744 \uc900\ube44\ud558\uc138\uc694<\/td><\/tr>\n            <tr><td>\uc5f4\ucc98\ub9ac<\/td><td>\ud544\uc694\ud55c \uc791\uc5c5 \uacbd\ub3c4\ub85c \uacbd\ud654 \ubc0f \ud15c\ud37c\ub9c1\ud569\ub2c8\ub2e4.<\/td><td>\ucd5c\uc885 \ub0b4\ub9c8\ubaa8\uc131\uc744 \ub2ec\uc131\ud569\ub2c8\ub2e4<\/td><\/tr>\n            <tr><td>\ucd5c\uc885 \ub9c8\ubb34\ub9ac<\/td><td>\uc5f0\uc0ad, EDM, PCBN \uacbd\uc9c8 \uc120\uc0ad \ub610\ub294 \uacbd\uc9c8 \ubc00\ub9c1\uc744 \uc0ac\uc6a9\ud558\uc2ed\uc2dc\uc624.<\/td><td>\ucd5c\uc885 \uacf5\ucc28 \ubc0f \ud45c\uba74 \uc870\ub3c4\ub97c \ub2ec\uc131\ud569\ub2c8\ub2e4.<\/td><\/tr>\n            <tr><td>\uc810\uac80<\/td><td>\ud06c\uae30, \ud45c\uba74 \uc0c1\ud0dc \ubc0f \uc5f0\uc0ad \uc190\uc0c1 \uc5ec\ubd80\ub97c \ud655\uc778\ud558\uc2ed\uc2dc\uc624.<\/td><td>\uacf5\uad6c\uc758 \uc870\uae30 \uace0\uc7a5 \uc704\ud5d8\uc744 \uc904\uc774\uc2ed\uc2dc\uc624<\/td><\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n      <p>\n        When heavy roughing has been done, stress relief around 650-677 \u00b0C (1200-1250 \u00b0F)\n        before hardening helps reduce distortion during the hardening cycle.
