and Pipes<\/strong><\/p>\n<p>Hafnium is a lustrous, silvery-gray transition metal. Hafnium is so chemically similar to zirconium that separating the two elements is extremely difficult. Most commercial hafnium is produced as a byproduct of zirconium refining. Hafnium is remarkably corrosion-resistant and an excellent absorber of neutrons, allowing its use in nuclear submarines and nuclear reactor control rods \u2014 a critical technology used to maintain fission reactions while preventing them from accelerating beyond control. Hafnium is also used in electronic equipment such as cathodes and capacitors, as well as in ceramics, photography flash bulbs, and light bulb filaments.<\/p>\n<div class=\"so-tbl-wrap\">\n<table>\n<tr class=\"so-tbl-head\">\n<td colspan=\"4\"><strong>Specification and Standard for Hafnium Alloy Tubes and Pipes<\/strong><\/td>\n<\/tr>\n<tr class=\"so-tbl-subhead\">\n<td><strong>Products<\/strong><\/td>\n<td><strong>Grades<\/strong><\/td>\n<td><strong>Size<\/strong><\/td>\n<td><strong>Standards<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Hafnium Alloy Seamless Tube \/ Pipe<br \/>Hafnium Alloy Welded Tube \/ Pipe<\/td>\n<td>Zirconium 702 (R60702)<br \/>Zirconium 704 (R60704)<br \/>Zirconium 705 (R60705)<br \/>Zircaloy-2 (R60802), Zircaloy-4 (R60804)<\/td>\n<td>Seamless Tube OD: 0.6\u201389 mm<br \/>Welded Tube OD: \u226589 mm<br \/>Wall Thickness: \u22650.2 mm<br \/>Length: 100\u201312000 mm<\/td>\n<td>ASTM B658\/B658M<br \/>ASTM B523\/B523M<br \/>ASTM B353\/B353M<\/td>\n<\/tr>\n<\/table><\/div>\n<div class=\"so-tbl-wrap\">\n<table>\n<tr class=\"so-tbl-head\">\n<td colspan=\"5\"><strong>Testing Provided for Hafnium Alloy Tubes and Pipes<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Chemical Composition<\/td>\n<td>Mechanical Properties Test<\/td>\n<td>Ultrasonic Test<\/td>\n<td>Flattening<\/td>\n<td>Flaring<\/td>\n<\/tr>\n<tr>\n<td>Eddy Current Test<\/td>\n<td>Dimensional Inspection<\/td>\n<td>Ultrasonic Flaw Detection<\/td>\n<td>Bending Test<\/td>\n<td>\u2014<\/td>\n<\/tr>\n<\/table><\/div>\n<div class=\"so-tbl-wrap\">\n<table>\n<tr class=\"so-tbl-head\">\n<td><strong>UNS<\/strong><\/td>\n<td><strong>Grade<\/strong><\/td>\n<td><strong>Zr + Hf (min %)<\/strong><\/td>\n<td><strong>Hafnium (max %)<\/strong><\/td>\n<td><strong>Fe + Cr (max %)<\/strong><\/td>\n<td><strong>Tin (%)<\/strong><\/td>\n<td><strong>Hydrogen (max %)<\/strong><\/td>\n<td><strong>Nitrogen (max %)<\/strong><\/td>\n<td><strong>Carbon (max %)<\/strong><\/td>\n<td><strong>Niobium (%)<\/strong><\/td>\n<td><strong>Oxygen (max %)<\/strong><\/td>\n<\/tr>\n<tr>\n<td>R60702<\/td>\n<td>Zr702<\/td>\n<td>99.2<\/td>\n<td>4.5<\/td>\n<td>0.2 max<\/td>\n<td>\u2014<\/td>\n<td>0.005<\/td>\n<td>0.025<\/td>\n<td>0.05<\/td>\n<td>\u2014<\/td>\n<td>0.16<\/td>\n<\/tr>\n<tr>\n<td>R60704<\/td>\n<td>Zr704<\/td>\n<td>97.5<\/td>\n<td>4.5<\/td>\n<td>0.2\u20130.4<\/td>\n<td>1.0\u20132.0<\/td>\n<td>0.005<\/td>\n<td>0.025<\/td>\n<td>0.05<\/td>\n<td>\u2014<\/td>\n<td>0.18<\/td>\n<\/tr>\n<tr>\n<td>R60705<\/td>\n<td>Zr705<\/td>\n<td>95.5<\/td>\n<td>4.5<\/td>\n<td>0.2 max<\/td>\n<td>\u2014<\/td>\n<td>0.005<\/td>\n<td>0.025<\/td>\n<td>0.05<\/td>\n<td>2.0\u20133.0<\/td>\n<td>0.18<\/td>\n<\/tr>\n<\/table><\/div>\n<\/p><\/div>\n<p>  <\/main>\n<\/div>\n<p><script>\njQuery(document).ready(function($){\n  $('#soAccHf2').on('click','>li>.so-acc-btn',function(){\n    var $b=$(this),$s=$b.next('.so-sub1'),isOpen=$b.hasClass('soopen');\n    $('#soAccHf2 >li>.so-acc-btn').removeClass('soopen');\n    $('#soAccHf2 >li>.so-sub1').removeClass('soopen');\n    if(!isOpen){$b.addClass('soopen');$s.addClass('soopen');}\n  });\n  $(document).on('click','.so-acc-btn2',function(){\n    $(this).toggleClass('soopen').next('.so-sub2').toggleClass('soopen');\n  });\n});\n<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Product Categories Pure Titanium &amp; Alloys &#9660; About Titanium Titanium Tube and Pipe Titanium Strip, Sheet &amp; Plate Titanium Bar and Rod Titanium Welded Wire and Wire Titanium Foil Titanium Forging Titanium Flange Titanium Pipe Fittings Titanium Casting Titanium Fastener Titanium Elliptical \/ Spherical Head Titanium Machining Parts Titanium Clad Plate Titanium Clad Copper Bar<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-7047","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages\/7047","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/comments?post=7047"}],"version-history":[{"count":1,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages\/7047\/revisions"}],"predecessor-version":[{"id":7048,"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/pages\/7047\/revisions\/7048"}],"wp:attachment":[{"href":"https:\/\/www.spreadon.net\/industrial1\/wp-json\/wp\/v2\/media?parent=7047"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
