Zone Costiere. Quale Acciaio Inox Scegliere?

Posted on
zone costiere

Nelle zone costiere è fondamentale la scelta dei materiali da utilizzare nella costruzione di opere edili e architettoniche.  Questa scelta, infatti, potrebbe ripercuotersi sulla sicurezza, sulla durabilità e sull’estetica delle opere stesse. Soprattutto, come in questo caso, in atmosfere decisamente “aggressive” come quelle marine (zone costiere).


Scegliere l’acciaio giusto. Quali fattori valutare?

Ma quali sono i fattori che bisogna valutare per scegliere l’acciaio giusto? Consigliamo di scegliere in base a:

  • Materiale

– Composizione chimica
– Finitura e stato della superficie
– Struttura
– Disegno del particolare
– Modalità di messa in opera

  • Agente aggressivo

– Composizione chimica
– Concentrazione
– Temperatura
– Velocità relativa rispetto al materiale

Atmosfere marine costiere. Quali materiali scegliere?

In questi casi risulta necessario scegliere materiali sia con il più alto tenore di Cromo che contenenti Molibdeno (AISI316 – 316L). Quest’ultimo, infatti, incrementa la resistenza del film protettivo rendendo maggiormente durevole l’acciaio inox. Ma quali sono le applicazioni dell’acciaio inox in edilizia? Principalmente nell’arredo urbano, nelle coperture, nelle facciate, nelle barre per cemento armato e tanto altro. Qualche altro esempio concreto? L’utilizzo nei parapetti dei lungomare, nelle zone portuali, ponti e pontili ecc..

 

Zone costiere – Perché scegliere l’acciaio inox?

Il primo fattore da non sottovalutare è quello economico. Infatti, anche se l’investimento iniziale per l’acquisto del prodotto sarà maggiore, questo si ripagherà  con un’elevata durabilità nel tempo del prodotto stesso.

    1. Hi Advance Hydrau Components,
      Thanks for writing to us.
      To talk about the rivets we start from their identification and their denomination (according to the ISO1891 of 2014) depending on their appearance and characteristics.

      The rivets consist mainly of two parts: the body and the mandrel.
      Blind rivets can be:

      – open end with pre-defined bursting mandrel and rounded head
      – open end with mandrel at pre-set breaking point and countersunk head
      – closed end with mandrel at pre-set breaking point and rounded head
      – closed end with mandrel at pre-set breaking point and countersunk head

      The body and mandrel of the rivets can also be made of different materials.
      To regulate this aspect there are regulations:

      – EN ISO 15977 is the standard specifying the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined breaking point spindle and rounded head, with aluminium alloy body (IAA) and steel spindle (St).
      – EN ISO 15978 is the standard specifying the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined breaking point spindle and countersunk head, with aluminium alloy body (AIA) and steel spindle (St).
      – EN ISO 15979 is the standard specifying the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined breaking spindle and rounded head, with steel body and spindle (St).
      – EN ISO 15980 is the standard that specifies the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined breaking point spindle and countersunk head, with steel body and spindle (St).
      – EN ISO 15981 is the standard specifying the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined bursting spindle and rounded head, with the body and spindle in Aluminium alloy (AIA).
      – EN ISO 15982 is the standard specifying the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined breaking point spindle and countersunk head, with the body and spindle in Aluminium alloy (AIA).
      – EN ISO 15983 is the standard specifying the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined breaking spindle and rounded head, with austenitic stainless steel body and spindle (A2).
      – EN ISO 15984 is the standard that specifies the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined breaking point spindle and countersunk head, with austenitic stainless steel body and spindle (A2).
      – EN ISO 116582 is the standard specifying the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined bursting spindle and rounded head, with copper body (Cu) and steel spindle (St) or bronze (br), or stainless steel (sst).
      – EN ISO 116583 is the standard specifying the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined bursting spindle and countersunk head, with the copper body (Cu) and steel spindle (St) or bronze (br) or stainless steel (sst).
      – EN ISO 116584 is the standard that specifies the dimensions, mechanical characteristics and applications of open end blind rivets with pre-defined bursting spindle and rounded head, with cupronichel body (nicu) and steel (St) or stainless steel spindle (sst).
      – EN ISO 116585 is the standard that specifies the dimensions, mechanical characteristics and applications of blind rivets with closed ends with pre-defined breaking point spindle and rounded head, with austenitic stainless steel body (A2) and stainless steel spindle (sst).
      – ISO 14588 is the standard that specifies the terminology and definition by type, performance characteristics and geometric for blind rivets, their adjustment and the adjustment of tools generally used in rivets.
      – ISO 14589 is the standard that determines which mechanical tests are carried out on blind rivets and how they are to be carried out.
