Thermal Shock Resistance Alloy UMCO50 <\/b><\/p>\n
XUNSHI NEW MATERIALS CO LTD supplies UMCO50 in forms of forgings, round bar, tube and so on.<\/p>\n
UMCO50is a heat-resistant cobalt alloy with excellent thermal shock resistance and wear resistance performance. It has great strength against sulfur-and vanadium-attacks. UmCo-50 has higher melting point compared to other cobalt based or nickel based heat-resistant alloys.<\/p>\n
UMCO50 is suitable for the environments that require oxidation resistance,high temperature strength and thermal corrosion resistance, thermal impact resistance and wear resistance.<\/p>\n
In a sulfur-containing oxidation atmosphere, it has an excellent thermal corrosion resistance to heavy oil or other fuel combustion medium. It is widely used in coal chemical nozzle.<\/p>\n
For example, the alloy used for skid rails at a steel mill undergoes regular use at 1350\u00b0C. <\/p>\n
Other alloys could not be used due to their low melting point in the application related to heat treatments and furnaces. But W.Nr. 2.4778 shows successful results.<\/p>\n

For example, even after repeating the heating and cooling cycle (1000-water cooling-7 seconds) for 500 times, no cracking occurred. As a practical example, the alloy was used for four and a half years as a tray which was heated up to 1000 in a heavy oil furnace to quench various quenching agents. Hardly any cracking occurred in W.Nr. 2.4778, whereas the 25Cr-12Ni alloys were able to be used for only 8 months in average. XUNSHI has strong strength in production of cobalt alloy. Available grades include Haynes 25(L605), Haynes 188, MP35N, MP159, Waspaloy,<\/p>","protected":false},"excerpt":{"rendered":" UMCO50 is a heat-resistant cobalt alloy with excellent thermal shock resistance and wear resistance performance.<\/p>","protected":false},"featured_media":1596,"template":"","meta":{"_acf_changed":false,"_seopress_robots_primary_cat":""},"product_brand":[],"product_cat":[52],"product_tag":[],"class_list":{"0":"post-1593","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-nickel-cobalt-alloy","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.xunshi-alloy.com\/pl\/wp-json\/wp\/v2\/product\/1593","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.xunshi-alloy.com\/pl\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.xunshi-alloy.com\/pl\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.xunshi-alloy.com\/pl\/wp-json\/wp\/v2\/media\/1596"}],"wp:attachment":[{"href":"https:\/\/www.xunshi-alloy.com\/pl\/wp-json\/wp\/v2\/media?parent=1593"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.xunshi-alloy.com\/pl\/wp-json\/wp\/v2\/product_brand?post=1593"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.xunshi-alloy.com\/pl\/wp-json\/wp\/v2\/product_cat?post=1593"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.xunshi-alloy.com\/pl\/wp-json\/wp\/v2\/product_tag?post=1593"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n\n
