This involves reheating the steel to an intermediate temperature below its critical transformation temperature.<\/p>\n<p>M2 high-speed tool steel requires\u00a02 to 4 tempering cycles\u00a0at a temperature of at least\u00a0540\u00b0C (1000\u00b0F), typically 3 cycles.<\/p>\n<p>For example, after austenitizing at\u00a01230\u00b0C (2250\u00b0F), the first tempering cycle is performed at\u00a0565\u00b0C (1050\u00b0F), followed by the second at\u00a0550\u00b0C (1025\u00b0F), and the third at\u00a0540\u00b0C (1000\u00b0F).<\/p>\n<p>For each tempering cycle, the soaking time is\u00a02 hours per inch (25 mm) of the thickest cross-section. After the first tempering, the M2 steel component must be completely cooled to room temperature before the next tempering can be performed.<\/p>\n<p>M2 \uc18c\uc7ac\ub97c \ud15c\ud37c\ub9c1\ud558\uba74 \uc794\ub958 \uc624\uc2a4\ud14c\ub098\uc774\ud2b8\uac00 \uc0c8\ub85c\uc6b4 \ub9c8\ub974\ud150\uc0ac\uc774\ud2b8\ub85c \ubcc0\ud658\ub418\uace0, \ubcf5\ud569 \ud0c4\ud654\ubb3c\uc774 \uc11d\ucd9c\ub418\uba70, \uac15\ucca0\uc758 2\ucc28 \uacbd\ub3c4\uac00 \ud06c\uac8c \ud5a5\uc0c1\ub429\ub2c8\ub2e4. \uc5ec\ub7ec \ubc88\uc758 \ud15c\ud37c\ub9c1 \uc0ac\uc774\ud074\uc744 \uac70\uce58\uba74 \ubbf8\uc138 \uad6c\uc870\uac00 \uac1c\uc120\ub418\uace0 \ub0b4\ub9c8\ubaa8\uc131\uc774 \ud5a5\uc0c1\ub418\uba70 \uc751\ub825\uc774 \ub354\uc6b1 \uc644\ud654\ub429\ub2c8\ub2e4.<\/p>\n<p>M2\uac15\uc740 \uc5f4\ucc98\ub9ac \ubd80\uc871 \uc0c1\ud0dc\uac00 \ub418\uc5b4\uc11c\ub294 \uc548 \ub41c\ub2e4\ub294 \uc810\uc744 \uc720\uc758\ud574\uc57c \ud569\ub2c8\ub2e4.<\/p>\n<p>Additionally, we recommend performing stress-relief tempering after subsequent processes such as grinding, welding, or electrical discharge machining (EDM), with the tempering temperature set\u00a014\u201328\u00b0C (25\u201350\u00b0F) below the final tempering temperature.<\/p>\n<p>M2\uac15\uc758 \uacbd\ub3c4-\ud15c\ud37c\ub9c1 \uc628\ub3c4 \uad00\uacc4\ud45c<\/p>\n<div class=\"ads2-tw\"><table class=\"ads2-t kv\"><tbody><tr><td><strong>\ud15c\ud37c\ub9c1 \uc628\ub3c4<\/strong><\/td><td><strong>\ub85d\uc6f0 C<\/strong><\/td><\/tr><tr><td>\ub2f4\uae08\uc9c8 \uc9c1\ud6c4<\/td><td>65<\/td><\/tr><tr><td>900\u00b0F\/480\u00b0C<\/td><td>64<\/td><\/tr><tr><td>950\u00b0F\/510\u00b0C<\/td><td>65<\/td><\/tr><tr><td>1000\u00b0F\/540\u00b0C<\/td><td>65<\/td><\/tr><tr><td>1050\u00b0F\/565\u00b0C<\/td><td>64<\/td><\/tr><tr><td>1100\u00b0F\/595\u00b0C<\/td><td>62<\/td><\/tr><tr><td>1150\u00b0F\/620\u00b0C<\/td><td>58<\/td><\/tr><tr><td>1200\u00b0F\/650\u00b0C<\/td><td>52<\/td><\/tr><\/tbody><\/table><\/div><figcaption>\uc2e4\ud5d8 \uc870\uac74: 1. \uc608\uc5f4 \uc628\ub3c4 1500\u00b0F\/815\u00b0C 2. \uacbd\ud654 \uc628\ub3c4 2250\u00b0F\/1230\u00b0C 3. \uc624\uc77c \ub610\ub294 \uc5fc \ub2f4\uae08\uc9c8 4. \ud654\ud559 \uc870\uc131: \ud0c4\uc18c 0.85%, \ub9dd\uac04 0.30%, \uaddc\uc18c 0.30%, \ud06c\ub86c 4.75%, \ubab0\ub9ac\ube0c\ub374 5.00%, \ubc14\ub098\ub4d0 1.90%, \ud145\uc2a4\ud150 6.35%<\/figcaption>\n<\/section>\n<section class=\"ads2-sec\">\n<h2>5. \ub3d9\ub4f1\ud55c \ub4f1\uae09<\/h2>\n<ul>\n<li><strong>\ubbf8\uad6d (AISI\/ASTM):<\/strong>\u00a0M2 (\uc774\uac83\uc774 \uc8fc\uc694 \uba85\uce6d\uc785\ub2c8\ub2e4)<\/li>\n\n\n\n<li><strong>\ub3c5\uc77c (DIN\/W-Nr):<\/strong>\u00a01.3343, HS6-5-2<\/li>\n\n\n\n<li><strong>\uc77c\ubcf8(JIS):<\/strong>\u00a0SKH51<\/li>\n\n\n\n<li><strong>\uc601\uad6d(BS):<\/strong>\u00a0BM2<\/li>\n\n\n\n<li><strong>\uc911\uad6d(GB):<\/strong>\u00a0W6Mo5Cr4V2<\/li>\n\n\n\n<li><strong>ISO:<\/strong>\u00a0HS 6-5-2<\/li>\n\n\n\n<li><strong>\ud504\ub791\uc2a4(AFNOR):<\/strong>\u00a0Z85WDCV06-05-04-02<\/li>\n\n\n\n<li><strong>\uc2a4\uc6e8\ub374(SS):<\/strong>\u00a02722<\/li>\n\n\n\n<li><strong>\ub7ec\uc2dc\uc544(GOST):<\/strong>\u00a0R6M5<\/li>\n<\/ul>\n<\/section>\n<section class=\"ads2-sec\">\n<h2>6.
