processing), the chromium content in these alloys facilitates the formation of a protective Cr-oxide scale. However, if the atmosphere shifts from oxidizing to reducing, the stability of this scale is compromised. In such cases, 800H remains superior for gas-to-gas exchangers, while 825 excels in liquid-to-liquid exchangers where acid dew point corrosion is a concern.<\/p>\n<p data-path-to-node=\"13\"><img decoding=\"async\" class=\"aligncenter size-full wp-image-2713\" src=\"http:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/03\/140.jpg\" alt=\"\uace0\uc5fc\ud654\ubb3c\uc758 \uc5f4\uad50\ud658\uae30\uc5d0 \uc778\ucf54\ub85c\uc774 \ud569\uae08\uc744 \uc0ac\uc6a9\ud558\ub294 \uc774\uc720\" width=\"1024\" height=\"765\" srcset=\"https:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/03\/140.jpg 1024w, https:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/03\/140-300x224.jpg 300w, https:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/03\/140-768x574.jpg 768w, https:\/\/www.nickelcasting.com\/wp-content\/uploads\/2026\/03\/140-16x12.jpg 16w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<h3 data-path-to-node=\"14\">\uc5d4\uc9c0\ub2c8\uc5b4\ub9c1 \ud3c9\uacb0<\/h3>\n<p data-path-to-node=\"15\">\uc9c0\uc815\ud558\ub294 \uacb0\uc815\uc740 <b data-path-to-node=\"15\" data-index-in-node=\"27\">\uc5f4\uad50\ud658\uae30\uc6a9 \uc778\ucf54\ub85c\uc774 \ud569\uae08<\/b> \uc81c\uc791\uc740 \uacb0\ucf54 \ube44\uc6a9\ub9cc\uc744 \uae30\uc900\uc73c\ub85c \ud574\uc11c\ub294 \uc548 \ub429\ub2c8\ub2e4. \uc81c\uc791\uc740 <span class=\"math-inline\" data-math=\"Pitting Resistance Equivalent Number (PREN)\" data-index-in-node=\"139\"><span class=\"katex\"><span class=\"katex-html\" aria-hidden=\"true\"><span class=\"base\"><span class=\"mord mathnormal\">P<\/span><span class=\"mord mathnormal\">i<\/span><span class=\"mord mathnormal\">tt<\/span><span class=\"mord mathnormal\">in<\/span><span class=\"mord mathnormal\">g<\/span><span class=\"mord mathnormal\">R<\/span><span class=\"mord mathnormal\">es<\/span><span class=\"mord mathnormal\">i<\/span><span class=\"mord mathnormal\">s<\/span><span class=\"mord mathnormal\">t<\/span><span class=\"mord mathnormal\">an<\/span><span class=\"mord mathnormal\">ce<\/span><span class=\"mord mathnormal\">Eq<\/span><span class=\"mord mathnormal\">u<\/span><span class=\"mord mathnormal\">i<\/span><span class=\"mord mathnormal\">v<\/span><span class=\"mord mathnormal\">a<\/span><span class=\"mord mathnormal\">l<\/span><span class=\"mord mathnormal\">e<\/span><span class=\"mord mathnormal\">n<\/span><span class=\"mord mathnormal\">tN<\/span><span class=\"mord mathnormal\">u<\/span><span class=\"mord mathnormal\">mb<\/span><span class=\"mord mathnormal\">er<\/span><span class=\"mopen\">(<\/span><span class=\"mord mathnormal\">PREN<\/span><span class=\"mclose\">)<\/span><\/span><\/span><\/span><\/span> \ubc0f \ubbf8\ub514\uc5b4\uc758 \ud2b9\uc815 \ud06c\ub9ac\ud504-\ud30c\uc5f4 \uace1\uc120. \uace0\uc555 \uc99d\uae30 \ubc1c\uc0dd\uae30\uc758 \uacbd\uc6b0 800H\/HT \ubcc0\ud615\uc740 \ud611\uc0c1\ud560 \uc218 \uc5c6\uc2b5\ub2c8\ub2e4. \ud574\uc218 \ub0c9\uac01 \uc2dc\uc2a4\ud15c \ub610\ub294 \uc778\uc0b0 \ud788\ud130\uc758 \uacbd\uc6b0, Mo \uc548\uc815\ud654 825 \ubcc0\ud615\uc740 \uce58\uba85\uc801\uc778 SCC\uc5d0 \ub300\ud574 \ud544\uc694\ud55c \ubcf4\ud5d8\uc744 \uc81c\uacf5\ud569\ub2c8\ub2e4.<\/p>\n<hr data-path-to-node=\"16\" \/>\n<h3 data-path-to-node=\"17\">\uad00\ub828 Q&amp;A:<\/h3>\n<p data-path-to-node=\"18\"><b data-path-to-node=\"18\" data-index-in-node=\"0\">1. \uc778\ucf5c\ub85c\uc774 800H\ub97c \uc120\ud638\ud558\ub294 \uc774\uc720 <a href=\"https:\/\/www.nickelcasting.com\/ko\/%eb%8b%88%ec%bc%88-%ed%95%a9%ea%b8%88\/%ec%9d%b8%ec%bd%94%eb%a1%9c%ec%9d%b4-%ea%b8%88%ec%86%8d-%ed%95%a9%ea%b8%88\/incoloy-800\/\">\uc778\ucf5c\ub85c\uc774 800<\/a> \uace0\uc628 \uad50\ud658\uae30\uc6a9?<\/b><\/p>\n<p data-path-to-node=\"18\">The &#8220;H&#8221;
