D812钴基焊条812是钛钙型药皮，铸造钴铬钨（司特立）合金焊芯的堆焊焊条，药皮用浸涂法制成的堆焊用焊条，宜采用直流反接。堆焊金属在650℃仍具有良好的耐磨性及耐腐蚀性能。用途：适用于高温高压阀门，高压泵的轴套筒和内套筒以及化纤设备的斩刀刃口等部位的堆焊。焊缝金属化学成分（％）CCrWMnSiFeCo1.0～1.726.0～32.07.0～10.0≤2.0≤2.0≤3.0余量堆焊层硬度HRC≥44-45注意事项：1、焊前焊条须经200℃左右烘1小时以上再行施焊接。2、焊时尽可能采用短弧，并且焊条与工作保持垂直。3、根据工作的大小和母材的种类须经300～600℃预热。宜采用小电流短弧焊接。4、焊后应在600～700℃回火1小时后在缓冷或将工作立即放入干燥和热的沙箱内或草灰中缓冷，以避免裂纹。5、堆焊层须经粗磨，如发现缺陷时，按上述步骤进行焊补及缓冷//varurl='http://detail.b2b.hc360.com/detail/turbine/action/sendbusnote.SendBusnoteAction/eventsubmit_dosendbusnote/doSendbusnote';//varurl='http://detail.b2b.hc360.com/detail/turbine/template/shop%2Casync%2Cbusnoteresult.html';varurl='http://b2b.hc360.com/action/shop,async,busnoteresult.html';functionsendIsOnline(){varcontent=document.getElementById('busnotecontent').value;varvaildcode=document.getElementById(vaildcode).value;varLoginTicket=document.getElementById(LoginTicket).value;if(content==){alert(请填写留言内容！);returnfalse;}if(content.length>2000){alert(留言内容不能超过2000个字！);returnfalse;}if(vaildcode==){alert(请填写验证码！);returnfalse;}if(vaildcode.length!=4){alert(请正确填写4位验证码！);returnfalse;}varmyAjax=newAjax.Request(url,{method:'post',parameters:{validcode:vaildcode,content:content,sendcontacter:'李经理',corname:'华北新锐特种耐磨焊条厂',email:'757745551@qq.com',tel:'86-0319-5398460',infoid:'112648408',infotype:'0',recvproviderid:'100013324679',sendproviderid:'100013324679',title:'供应D812钴基焊条',LoginTicket:LoginTicket},onComplete:function(req){ret=req.responseXML;parxmlrs(ret);},onException:function(e){alert('系统故障暂时无法返回正确结果，请您稍后再试试');}});}functionsendNotOnline(){varvaildcode=document.getElementById(vaildcode).value;varcontent=document.getElementById('busnotecontent').value;varsendcontacter=document.getElementById('busnoteyourname').value;varcorname=document.getElementById('busnotecorname').value;varemail=document.getElementById('busnoteemail').value;vartel=document.getElementById('busnotetel').value;varLoginTicket=document.getElementById(LoginTicket).value;if(sendcontacter==){alert(请输入您的姓名!);returnfalse;}if(sendcontacter.length>31){alert(您输入的姓名太长，请不要超过30个字!);returnfalse;}if(corname.length>51){alert(您输入的公司名称太长，请不要超过50个字!);returnfalse;}if(email==){alert(请输入您的电子邮件!);returnfalse;}if(email.length>51){alert(您输入的Email太长，请不要超过50个字!);returnfalse;}if(content==){alert(请填写留言内容！);returnfalse;}if(content.length>2000){alert(留言内容不能超过2000个字！);returnfalse;}if(vaildcode==){alert(请填写验证码！);returnfalse;}if(vaildcode.length!=4){alert(请正确填写4位验证码！);returnfalse;}varmyAjax=newAjax.Request(url,{method:'post',parameters:{validcode:vaildcode,content:content,sendcontacter:sendcontacter,corname:corname,email:email,tel:tel,infoid:'112648408',infotype:'0',recvproviderid:'100013324679',sendproviderid:'0',title:'供应D812钴基焊条',LoginTicket:LoginTicket},onComplete:function(req){ret=req.responseXML;parxmlrs(ret);},onException:function(e){alert('系统故障暂时无法返回正确结果，请您稍后再试试'+e);}});}functionparxmlrs(obj){varbusnoters=obj.getElementsByTagName('busnoteresult');vartckey=busnoters[0].getElementsByTagName('key')[0].firstChild.data;vartcvalue=busnoters[0].getElementsByTagName('value')[0].firstChild.data;varstatus=busnoters[0].getElementsByTagName('status')[0].firstChild.data;varreturninfo=busnoters[0].getElementsByTagName('returninfo')[0].firstChild.data;if(status==1){document.getElementById(vaildcode).value=;document.getElementById('busnotecontent').value=;document.getElementById('LoginTicket').value=tckey;varnewsrc='http://my.b2b.hc360.com/my/ValidImage.jsp?Seed='+tcvalue;document.getElementById('validimg').src=newsrc;alert(发送留言成功);}else{document.getElementById(vaildcode).value=;document.getElementById('LoginTicket').value=tckey;varnewsrc='http://my.b2b.hc360.com/my/ValidImage.jsp?Seed='+tcvalue;document.getElementById('validimg').src=newsrc;alert(returninfo);}})
