Some steels lose toughness and become more sensitive to brittle fracture. Moisture can freeze around threads. Condensation may create corrosion during defrost cycles. Temperature changes can also reduce preload if the connected parts expand and contract differently.<\/p>\n\n\n\n<p>Zu den h\u00e4ufigsten Risiken geh\u00f6ren:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Brittle fracture in unsuitable steel<\/li>\n\n\n\n<li>Corrosion from condensation and cleaning water<\/li>\n\n\n\n<li>Thread seizure after freezing or corrosion<\/li>\n\n\n\n<li>Preload loss from thermal cycling<\/li>\n\n\n\n<li>Coating damage during installation<\/li>\n\n\n\n<li>Failure of non-metallic locking elements<\/li>\n\n\n\n<li>Poor maintenance access in refrigerated spaces<\/li>\n<\/ul>\n\n\n\n<p>For load-bearing or safety-related assemblies, buyers should review <a href=\"https:\/\/xzfastener.com\/de\/products-category\/high-strength-fasteners\/\">hochfeste Verbindungselemente<\/a> and confirm low-temperature suitability before ordering.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Define the Temperature Range First<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Normal Cold Storage vs Low-Temperature Service<\/h3>\n\n\n\n<p>Not every cold application requires special low-temperature alloy bolting.

They may be suitable for non-critical cold storage structures, racks, brackets, and indoor assemblies if corrosion is controlled.<\/p>\n\n\n\n<p>However, general carbon steel should not be assumed safe for critical low-temperature or pressure applications. If the joint is safety-related, impact toughness and standard compliance must be checked.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Alloy Steel for Low-Temperature Bolting<\/h3>\n\n\n\n<p>For pressure equipment, valves, flanges, and piping systems in low-temperature service, project specifications may require alloy steel bolting under standards such as ASTM A320.<\/p>\n\n\n\n<p>Grades such as L7 or L7M may be used depending on design requirements. These are not ordinary high-strength bolts. They require proper material control, heat treatment, mechanical testing, and impact-related verification where specified.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Edelstahl Befestigungselemente<\/h3>\n\n\n\n<p>Stainless steel is often selected for cold storage because it resists corrosion from condensation, washdown, and cleaning chemicals. 304 stainless may work in mild environments. 316 stainless is preferred where chlorides, chemicals, or stronger corrosion exposure exist.<\/p>\n\n\n\n<p>K\u00e4ufer k\u00f6nnen vergleichen <a href=\"https:\/\/xzfastener.com\/de\/fastener-material\/stainless-steel\/\">Edelstahl Befestigungselemente<\/a> when hygiene, corrosion resistance, or long service life is important.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Material<\/th><th>Beste Verwendung<\/th><th>Schl\u00fcsselbeschr\u00e4nkung<\/th><\/tr><\/thead><tbody><tr><td>Kohlenstoffstahl<\/td><td>General brackets, racks, non-critical indoor parts<\/td><td>Needs coating and toughness review<\/td><\/tr><tr><td>Alloy steel low-temperature bolting<\/td><td>Pressure systems, valves, flanges<\/td><td>Requires standard and test control<\/td><\/tr><tr><td>304 Edelstahl<\/td><td>Cold rooms, equipment covers, light corrosion exposure<\/td><td>Begrenzte Chloridbest\u00e4ndigkeit<\/td><\/tr><tr><td>316 Edelstahl<\/td><td>Washdown, coastal cold storage, chemical exposure<\/td><td>H\u00f6here Kosten<\/td><\/tr><tr><td>Duplex Edelstahl<\/td><td>Higher strength and corrosive low-temperature service<\/td><td>Longer lead time and project-specific approval<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Beschichtung und Korrosionsschutz<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Condensation Is the Main Enemy<\/h3>\n\n\n\n<p>Cold storage fasteners often corrode because temperature changes create moisture.
