\n
Korrosionsbest\u00e4ndigkeit von Duplex-Kegelventilen<\/h6>\n

Wie bei allen nichtrostenden St\u00e4hlen h\u00e4ngt die Korrosionsbest\u00e4ndigkeit haupts\u00e4chlich von der Zusammensetzung des nichtrostenden Stahls ab. F\u00fcr die Best\u00e4ndigkeit gegen Chlorid-Lochfra\u00df und Spaltkorrosion ist der Gehalt an Chrom, Molybd\u00e4n und Stickstoff am wichtigsten. Die Korrosionsbest\u00e4ndigkeit von nichtrostenden Duplexst\u00e4hlen ist \u00e4hnlich wie die von austenitischen nichtrostenden St\u00e4hlen, d. h. von Typ 304 oder 316 (z. B. LDX 2101\u00a9) bis zu 6%-Molybd\u00e4n (z. B. SAF 2507\u00a9).<\/p>\n

\n
Die Kosten f\u00fcr Duplex-Kegelventile<\/h6>\n

Nichtrostende Duplexst\u00e4hle haben einen geringeren Nickel- und Molybd\u00e4ngehalt als ihre austenitischen Gegenst\u00fccke mit \u00e4hnlicher Korrosionsbest\u00e4ndigkeit. Aufgrund des geringeren Legierungsgehalts k\u00f6nnen nichtrostende Duplexst\u00e4hle kosteng\u00fcnstiger sein, insbesondere in Zeiten hoher Legierungszuschl\u00e4ge. Dar\u00fcber hinaus ist es oft m\u00f6glich, die Querschnittsdicke von nichtrostendem Duplexstahl zu verringern, da er im Vergleich zu austenitischem nichtrostendem Stahl eine h\u00f6here Streckgrenze aufweist. Diese Kombination kann zu erheblichen Kosten- und Gewichtseinsparungen im Vergleich zu einer L\u00f6sung aus austenitischem Edelstahl f\u00fchren.<\/p>\n

\n
Anwendungen von Duplex-Kegelventilen<\/h6>\n

Duplex-Ventile sind vielseitig und k\u00f6nnen in verschiedenen Anwendungen eingesetzt werden, in denen eine zuverl\u00e4ssige und effiziente Durchflussregelung erforderlich ist, z. B. in der chemischen Verarbeitung, in \u00d6l- und Gaspipelines, bei der Wasseraufbereitung, bei der Stromerzeugung usw.<\/p>","protected":false},"excerpt":{"rendered":"

Nichtrostende Duplexst\u00e4hle werden so genannt, weil sie ein zweiphasiges Gef\u00fcge aufweisen, das aus K\u00f6rnern von ferritischem und austenitischem nichtrostendem Stahl besteht.<\/p>\n

Festigkeit: Duplex-Edelst\u00e4hle sind etwa doppelt so fest wie normale austenitische oder ferritische Edelst\u00e4hle.<\/p>\n

Super-Duplex-Ventile werden in vielen Industriezweigen eingesetzt, z. B. in der Petrochemie, der chemischen Industrie, der Lebensmittelverarbeitung, der \u00d6l- und Gasindustrie.<\/p>","protected":false},"featured_media":701,"comment_status":"open","ping_status":"closed","template":"","meta":{"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":""},"product_brand":[],"product_cat":[27],"product_tag":[],"class_list":{"0":"post-659","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-plug-valve","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple","12":"entry","13":"content-bg","14":"loop-entry"},"yoast_head":"\nDuplex Plug Valves - jstvalve.com<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/jstvalve.com\/de\/produkt\/duplex-plug-valves\/\" \/>\n<meta property=\"og:locale\" content=\"de_DE\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Duplex Plug Valves\" \/>\n<meta property=\"og:description\" content=\"Duplex stainless steels are called \u201cduplex\u201d because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel.
