By alloying approximately 63% nickel with 28-34% copper, the material benefits from the noble characteristics of both elements. Unlike stainless steels, which rely on a fragile chromium-oxide &#8220;passive&#8221; layer that can be stripped away by chlorides or reducing agents, Monel is inherently resistant to many non-oxidizing conditions.<\/p>\n<p data-path-to-node=\"6\">\u0641\u064a \u0648\u062d\u062f\u0627\u062a \u0627\u0644\u0623\u0644\u0643\u0644\u0629 \u0628\u062d\u0645\u0636 \u0627\u0644\u0647\u064a\u062f\u0631\u0648\u0641\u0644\u0648\u0631\u064a\u0643 (HF) \u0641\u064a \u0648\u062d\u062f\u0627\u062a \u0627\u0644\u0623\u0644\u0643\u0644\u0629 \u0628\u062d\u0645\u0636 \u0627\u0644\u0647\u064a\u062f\u0631\u0648\u0641\u0644\u0648\u0631\u064a\u0643 (HF) - \u0623\u062d\u062f \u0623\u0643\u062b\u0631 \u0627\u0644\u0628\u064a\u0626\u0627\u062a \u0639\u062f\u0648\u0627\u0646\u064a\u0629 \u0641\u064a \u0627\u0644\u062a\u0643\u0631\u064a\u0631 - \u064a\u0639\u062a\u0628\u0631 \u0627\u0644\u0645\u0648\u0646\u064a\u0644 400 \u0647\u0648 \u0627\u0644\u0645\u0639\u064a\u0627\u0631 \u0627\u0644\u0635\u0646\u0627\u0639\u064a. \u0641\u0647\u0648 \u064a\u062d\u0627\u0641\u0638 \u0639\u0644\u0649 \u0645\u0639\u062f\u0644 \u062a\u0622\u0643\u0644 \u0645\u0646\u062e\u0641\u0636 \u0641\u064a \u062c\u0645\u064a\u0639 \u0627\u0644\u062a\u0631\u0643\u064a\u0632\u0627\u062a \u062d\u062a\u0649 \u0646\u0642\u0637\u0629 \u0627\u0644\u063a\u0644\u064a\u0627\u0646\u060c \u0634\u0631\u064a\u0637\u0629 \u0623\u0644\u0627 \u064a\u0643\u0648\u0646 \u0627\u0644\u062d\u0645\u0636 \u0639\u0627\u0644\u064a \u0627\u0644\u062a\u0647\u0648\u064a\u0629.<\/p>\n<hr data-path-to-node=\"7\" \/>\n<h3 data-path-to-node=\"8\">\u0627\u0644\u0623\u062f\u0627\u0621 \u0627\u0644\u0645\u0642\u0627\u0631\u0646: \u0645\u0648\u0646\u064a\u0644 400 \u0645\u0642\u0627\u0628\u0644 \u0627\u0644\u0633\u0628\u0627\u0626\u0643 \u0627\u0644\u0634\u0627\u0626\u0639\u0629<\/h3>\n<p data-path-to-node=\"9\">\u064a\u0628\u0631\u0632 \u0627\u0644\u062c\u062f\u0648\u0644 \u0627\u0644\u062a\u0627\u0644\u064a \u0645\u0642\u0627\u064a\u064a\u0633 \u0623\u062f\u0627\u0621 \u0627\u0644\u0645\u0648\u0646\u064a\u0644 \u0645\u0642\u0627\u0631\u0646\u0629\u064b \u0628\u0627\u0644\u0633\u0628\u0627\u0626\u0643 \u0627\u0644\u0635\u0646\u0627\u0639\u064a\u0629 \u0627\u0644\u0623\u062e\u0631\u0649 \u0641\u064a \u0648\u0633\u0627\u0626\u0637 \u062a\u0622\u0643\u0644 \u0645\u062d\u062f\u062f\u0629.<\/p>\n<table data-path-to-node=\"10\">\n<thead>\n<tr>\n<td><strong>\u0627\u0644\u0628\u064a\u0626\u0629<\/strong><\/td>\n<td><strong>\u0645\u0648\u0646\u064a\u0644 400<\/strong><\/td>\n<td><strong>\u0633\u062a\u0627\u0646\u0644\u0633 \u0633\u062a\u0627\u0646\u0644\u0633 316L<\/strong><\/td>\n<td><strong>\u0633\u0628\u064a\u0643\u0629 \u0647\u0627\u0633\u062a\u064a\u0644\u0648\u064a C276<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"10,1,0,0\"><b data-path-to-node=\"10,1,0,0\" data-index-in-node=\"0\">\u063a\u0644\u064a\u0627\u0646 \u062d\u0645\u0636 70% HF acid 70%<\/b><\/span><\/td>\n<td><span data-path-to-node=\"10,1,1,0\">\u0645\u0645\u062a\u0627\u0632<\/span><\/td>\n<td><span data-path-to-node=\"10,1,2,0\">\u0627\u0644\u0641\u0634\u0644 \u0627\u0644\u0633\u0631\u064a\u0639<\/span><\/td>\n<td><span data-path-to-node=\"10,1,3,0\">\u062c\u064a\u062f<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"10,2,0,0\"><b data-path-to-node=\"10,2,0,0\" data-index-in-node=\"0\">\u0645\u064a\u0627\u0647 \u0627\u0644\u0628\u062d\u0631 \u0627\u0644\u0631\u0627\u0643\u062f\u0629<\/b><\/span><\/td>\n<td><span data-path-to-node=\"10,2,1,0\">\u062e\u0627\u0636\u0639 \u0644\u0644\u062a\u0646\u0642\u0631<\/span><\/td>\n<td><span data-path-to-node=\"10,2,2,0\">\u062a\u0623\u0644\u064a\u0628 \u0645\u0639\u062a\u062f\u0644<\/span><\/td>\n<td><span data-path-to-node=\"10,2,3,0\">\u0645\u062a\u0641\u0648\u0642\u0629<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"10,3,0,0\"><b data-path-to-node=\"10,3,0,0\" data-index-in-node=\"0\">\u0645\u064a\u0627\u0647 \u0627\u0644\u0628\u062d\u0631 \u0627\u0644\u0645\u062a\u062f\u0641\u0642\u0629 (&gt;

In acids like Hydrofluoric or Sulfuric, the presence of dissolved oxygen (aeration) significantly increases the corrosion rate. Oxygen acts as a depolarizer, facilitating the cathodic reaction and stripping the protective film. For high-aeration scenarios, a more highly alloyed material like Hastelloy C276 may be required.<\/p>\n<p data-path-to-node=\"20\"><b data-path-to-node=\"20\" data-index-in-node=\"0\">\u06332: \u0647\u0644 \u064a\u0645\u0643\u0646 \u0627\u0633\u062a\u062e\u062f\u0627\u0645 \u0645\u0648\u0646\u064a\u0644 K-500 \u0641\u064a \u0627\u0644\u063a\u0627\u0632 \u0627\u0644\u062d\u0627\u0645\u0636 (<span class=\"math-inline\" data-math=\"H_2S\" data-index-in-node=\"41\">$H_2S$<\/span>) \u0627\u0644\u062e\u062f\u0645\u0629 \u0648\u0641\u0642\u064b\u0627 \u0644\u0645\u0639\u0627\u064a\u064a\u0631 NACE\u061f<\/b><\/p>\n<p data-path-to-node=\"20\">\u062c2: \u0646\u0639\u0645\u060c \u0648\u0644\u0643\u0646 \u0645\u0639 \u0648\u062c\u0648\u062f \u0642\u064a\u0648\u062f. \u0639\u0644\u0649 \u0627\u0644\u0631\u063a\u0645 \u0645\u0646 \u0623\u0646 K-500 \u064a\u062a\u0645\u062a\u0639 \u0628\u0645\u0642\u0627\u0648\u0645\u0629 \u0639\u0627\u0645\u0629 \u0645\u0645\u062a\u0627\u0632\u0629\u060c \u0625\u0644\u0627 \u0623\u0646\u0647 \u064a\u0645\u0643\u0646 \u0623\u0646 \u064a\u0643\u0648\u0646 \u0639\u0631\u0636\u0629 \u0644\u0644\u062a\u0634\u0642\u0642 \u0627\u0644\u0646\u0627\u062a\u062c \u0639\u0646 \u0627\u0644\u0625\u062c\u0647\u0627\u062f \u0627\u0644\u0647\u064a\u062f\u0631\u0648\u062c\u064a\u0646\u064a (HISC) \u0625\u0630\u0627 \u062a\u062c\u0627\u0648\u0632\u062a \u0627\u0644\u0635\u0644\u0627\u0628\u0629 \u0645\u0633\u062a\u0648\u064a\u0627\u062a \u0645\u0639\u064a\u0646\u0629 (\u0639\u0627\u062f\u0629\u064b 35 HRC) \u0623\u0648 \u0625\u0630\u0627 \u0627\u0642\u062a\u0631\u0646 \u0628\u0627\u0644\u0641\u0648\u0644\u0627\u0630 \u0627\u0644\u0645\u062c\u0644\u0641\u0646\/\u0627\u0644\u0645\u062d\u0645\u064a \u0628\u0627\u0644\u0643\u0627\u062b\u0648\u062f \u0627\u0644\u0630\u064a \u064a\u0648\u0644\u062f \u0627\u0644\u0647\u064a\u062f\u0631\u0648\u062c\u064a\u0646 \u0627\u0644\u0646\u0627\u0634\u0626.<\/p>\n<p data-path-to-node=\"21\"><b data-path-to-node=\"21\" data-index-in-node=\"0\">\u06333: \u0644\u0645\u0627\u0630\u0627 \u064a\u064f\u0641\u0636\u0644 \u0627\u0644\u0645\u0648\u0646\u064a\u0644 \u0639\u0644\u0649 \u0627\u0644\u062a\u064a\u062a\u0627\u0646\u064a\u0648\u0645 \u0641\u064a \u0628\u0639\u0636 \u0623\u0646\u0638\u0645\u0629 \u0623\u0646\u0627\u0628\u064a\u0628 \u0645\u064a\u0627\u0647 \u0627\u0644\u0628\u062d\u0631\u061f<\/b><\/p>\n<p data-path-to-node=\"21\">A3: \u0641\u064a \u062d\u064a\u0646 \u0623\u0646 \u0627\u0644\u062a\u064a\u062a\u0627\u0646\u064a\u0648\u0645 \u064a\u0648\u0641\u0631 \u0645\u0642\u0627\u0648\u0645\u0629 \u0634\u0628\u0647 \u0645\u062b\u0627\u0644\u064a\u0629 \u0644\u0644\u062a\u0622\u0643\u0644\u060c \u063a\u0627\u0644\u0628\u064b\u0627 \u0645\u0627 \u064a\u064f\u0641\u0636\u0644 \u0627\u0633\u062a\u062e\u062f\u0627\u0645 \u0627\u0644\u0645\u0648\u0646\u064a\u0644 \u0641\u064a \u0627\u0644\u0645\u0628\u0627\u062f\u0644\u0627\u062a \u0627\u0644\u062d\u0631\u0627\u0631\u064a\u0629 \u0648\u0627\u0644\u0623\u0646\u0627\u0628\u064a\u0628 \u0628\u0633\u0628\u0628 \u062a\u0648\u0635\u064a\u0644\u0647 \u0627\u0644\u062d\u0631\u0627\u0631\u064a \u0627\u0644\u0641\u0627\u0626\u0642 \u0648\u062e\u0635\u0627\u0626\u0635\u0647 \u0627\u0644\u0637\u0628\u064a\u0639\u064a\u0629 \u0627\u0644\u0645\u0636\u0627\u062f\u0629 \u0644\u0644\u0642\u0627\u0630\u0648\u0631\u0627\u062a. \u0648\u062a\u0645\u0646\u0639 \u0623\u064a\u0648\u0646\u0627\u062a \u0627\u0644\u0646\u062d\u0627\u0633 \u0627\u0644\u0645\u0646\u0637\u0644\u0642\u0629 \u0639\u0644\u0649 \u0627\u0644\u0633\u0637\u062d \u0646\u0645\u0648 \u0627\u0644\u0628\u0631\u0646\u0642\u064a\u0644 \u0648\u0627\u0644\u0637\u062d\u0627\u0644\u0628\u060c \u0645\u0645\u0627 \u064a\u062d\u0627\u0641\u0638 \u0639\u0644\u0649 \u0643\u0641\u0627\u0621\u0629 \u062a\u062f\u0641\u0642 \u0639\u0627\u0644\u064a\u0629 \u0628\u062f\u0648\u0646 \u0645\u0628\u064a\u062f\u0627\u062a \u062d\u064a\u0648\u064a\u0629 \u0643\u064a\u0645\u064a\u0627\u0626\u064a\u0629.<\/p>","protected":false},"excerpt":{"rendered":"<p>In the demanding landscape of chemical processing and marine engineering, material failure is rarely an option.
