Cad é an difríocht idir Inconel agus cóimhiotail?

Cad é an difríocht idir Inconel agus cóimhiotail?

 

 

Is dhá theaghlach éagsúla iad Inconel agus Incoloy de chóimhiotail nicil-bhunaithe a d'fhorbair Specialty Metals Corporation ar dtús (ar leis na trádmharcanna Inconel agus Incoloy).

Is cóimhiotail nicil-bhunaithe iad gráid Incoloy atá cóimhiotal go príomha le cróimiam. Tá breis agus dosaen grád éagsúil i raon Incoloy faoi láthair, ach is iad Incoloy 825 agus Incoloy 925 an dá ghrád Incoloy is mó a úsáidtear.

Is cóimhiotail nicil-bhunaithe iad gráid inconel, arís cóimhiotal go príomha le cróimiam. Mar sin féin, is gnách go mbíonn cion nicil i bhfad níos airde acu ná gráid Incoloy, ag soláthar feidhmíochta feabhsaithe ag teochtaí níos airde agus ag an am céanna ag coinneáil neart níos mó. Mar sin féin, tá siad níos costasaí i gcoitinne mar gheall ar an ábhar nicil méadaithe i gcomparáid le cóimhiotail Incoloy. Tá suas le 20 grád éagsúil i raon Inconel, ach is dócha gurb iad Inconel 718 agus Inconel 625 na cinn is cáiliúla agus is mó a úsáidtear.

Inconel and Incoloy are two different families of nickel-based alloys originally developed by Specialty Metals Corporation (which owns the Inconel and Incoloy trademarks). Incoloy grades are nickel-based alloys primarily alloyed with chromium. There are currently over a dozen different grades in the Incoloy range, but the two most widely used Incoloy grades are Incoloy 825 and Incoloy 925. Inconel grades are nickel-based alloys, again primarily alloyed with chromium. However, they typically have a much higher nickel content than Incoloy grades, providing improved performance at higher temperatures while retaining more strength. However, they are generally more expensive due to the increased nickel content compared to Incoloy alloys. There are up to 20 different grades in the Inconel range, but Inconel 718 and Inconel 625 are probably the most well-known and used.

Níl Inconel 625 chomh láidir ach tá friotaíocht creimeadh den scoth aige ar éagsúlacht timpeallachtaí crua, rud a chiallaíonn go n-úsáidtear go coitianta é le haghaidh comhpháirteanna sa tionscal próiseála ceimiceach. Tá Inconel 725 cosúil le Inconel 625 i gcomhdhéanamh agus friotaíocht creimeadh. Mar sin féin, déanann breisithe cóimhiotail subtle agus próiseas cóireála teasa breise a neart a dhúbailt.

Is grád níos láidre é Inconel 718 a choinníonn an chuid is mó dá neart ag teochtaí ardaithe. Mar sin, úsáidtear é go forleathan in iarratais aeraspáis cosúil le tuirbíní, agus i raon úsáidí deiridh ola agus gáis.

Stocann GNEE cóimhiotal 625 agus barraí cruinne cóimhiotail 718 ar thrastomhais 5/8"-10" (15.87-254 mm) agus barraí cruinne cóimhiotail 725 i dtrastomhais 1"-4" (25.{ {11}}.6 mm).
