The Pitting Resistance Equivalent Number (PREN) is a standard calculation used to predict an alloy&#8217;s defense against this. Thanks to high levels of molybdenum and tungsten, hastelloy corrosion resistance boasts some of the highest PREN values in the metallurgical world, making it virtually immune to chloride-induced stress corrosion cracking.<\/p>\n<h4 data-path-to-node=\"14\">\ube44\uad50 \ubd84\uc11d: \ud558\uc2a4\ud154\ub85c\uc774\uc640 \uae30\ud0c0 \uc81c\ud488 \ube44\uad50<\/h4>\n<p data-path-to-node=\"15\">\uac00\uce58 \uc81c\uc548\uc744 \ub354 \uc798 \uc774\ud574\ud558\ub824\uba74 \uc77c\ubc18\uc801\uc778 \uc7ac\ub8cc\uc758 \uc131\ub2a5\uc744 \ub2e4\uc74c\uacfc \ube44\uad50\ud574\ubcf4\uc2ed\uc2dc\uc624. <a href=\"https:\/\/www.nickelcasting.com\/it\/leghe-di-nichel\/leghe-di-nichel-hastelloy\/hastelloy-c-276\/\">\ud558\uc2a4\ud154\ub85c\uc774 C-276<\/a>.<\/p>\n<table data-path-to-node=\"16\">\n<thead>\n<tr>\n<td>\uc7ac\ub8cc<\/td>\n<td>PREN \uac12(\ub300\ub7b5)<\/td>\n<td>\ud53c\ud305\uc5d0 \ub300\ud55c \ub0b4\uc131<\/td>\n<td>\ud669\uc0b0 \uc131\ub2a5<\/td>\n<td>\uc5fc\ud654\ubb3c \uc751\ub825 \uade0\uc5f4<\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>316 \uc2a4\ud14c\uc778\ub9ac\uc2a4 \uc2a4\ud2f8<\/td>\n<td>~25<\/td>\n<td>\ubcf4\ud1b5<\/td>\n<td>Poor<\/td>\n<td>\ucde8\uc57d\ud55c<\/td>\n<\/tr>\n<tr>\n<td>254 SMO(\uc774\uc911)<\/td>\n<td>~43<\/td>\n<td>Good<\/td>\n<td>\ubcf4\ud1b5<\/td>\n<td>\uc800\ud56d\uc131<\/td>\n<\/tr>\n<tr>\n<td>\ud558\uc2a4\ud154\ub85c\uc774 C-276<\/td>\n<td>&gt;60<\/td>\n<td>\uc6b0\uc218<\/td>\n<td>\uc6b0\uc218<\/td>\n<td>\uba74\uc5ed<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h4 data-path-to-node=\"17\">\ud558\uc2a4\ud154\ub85c\uc774 \ub0b4\uc2dd\uc131 \uadf9\ub300\ud654\ub97c \uc704\ud55c \uc62c\ubc14\ub978 \ub4f1\uae09 \uc120\ud0dd<\/h4>\n<p data-path-to-node=\"18\">\ubaa8\ub4e0 \ud558\uc2a4\ud154\ub85c\uc774\uac00 \ub611\uac19\uc774 \ub9cc\ub4e4\uc5b4\uc9c0\ub294 \uac83\uc740 \uc544\ub2d9\ub2c8\ub2e4. \ud558\uc2a4\ud154\ub85c\uc774\uc758 \ub0b4\uc2dd\uc131\uc744 \uadf9\ub300\ud654\ud558\ub824\uba74 \ud2b9\uc815 \ub9e4\uccb4\uc5d0 \ub9de\ub294 \ub4f1\uae09\uc744 \uc120\ud0dd\ud574\uc57c \ud569\ub2c8\ub2e4:<\/p>\n<ul data-path-to-node=\"19\">\n<li>\n<p data-path-to-node=\"19,0,0\">Hastelloy C-276: The &#8220;workhorse&#8221; of the industry.
