Space product assurance - Material selection for controlling stress-corrosion cracking

This Standard covers the following processes of the general materials, mechanicals parts and processes (MMPP) flow of ECSS-Q-ST-70:
•   The selection of metal alloys for which preference is given to approved data sources (Table 5 1 to Table 5 3)
•   The criticality analysis to determine if a stress corrosion cracking (SCC) evaluation is necessary
This Standard sets forth the criteria to be used in the selection of materials for spacecraft and associated equipment and facilities so that failure resulting from stress-corrosion is prevented.
It is intended to provide general criteria to be used in stress-corrosion cracking control, which begins during design thanks to a methodological material selection.
This document does not intend to include all factors and criteria necessary for the total control of stress­corrosion cracking in all alloys.
The criteria established in this Standard are only applicable to designs for service involving exposure conditions similar to testing conditions
As regards weldments, this Standard is applicable to aluminium alloys, selected stainless steels in the 300 series and alloys listed in Table 5 1.
This Standard is not applicable to listed materials whose behaviour differs at elevated temperature and in specific chemical.
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

Raumfahrtproduktsicherung - Kriterien für die Werkstoffwahl zur Vermeidung von Spannungsrisskorrosion

Assurance produit des projets spatiaux - Sélection des matériaux en vue d'éviter leur fissuration par corrosion sous contrainte

La présente norme couvre les processus suivants des flux généraux de matériaux, composants mécaniques et procédés (MMPP) de l'ECSS-Q-ST-70 :
 la sélection des alliages métalliques pour lesquels la préférence est donnée à des sources de données approuvées (Tableau 5-1 à Tableau 5-3) ;
 l'analyse de criticité permettant de déterminer si une évaluation de la fissuration par corrosion sous contrainte (SCC) est nécessaire.
La présente norme détaille les critères à utiliser pour sélectionner les matériaux destinés aux engins spatiaux et aux équipements et installations associés de sorte à éviter toute défaillance due à la corrosion sous contrainte.
Elle vise à fournir les critères généraux à utiliser pour contrôler la fissuration par corrosion sous contrainte, en commençant dès le stade de la conception grâce à une sélection méthodique des matériaux.
Le présent document n'a pas pour but de donner de façon exhaustive tous les facteurs et critères nécessaires pour éviter la fissuration par corrosion sous contrainte chez tous les alliages.
Les critères définis dans la présente norme ne s'appliquent qu'aux conceptions d’équipements destinés à fonctionner dans des conditions d’exposition similaires à celles des conditions d'essai.
En ce qui concerne les ensembles soudés, la présente norme s'applique aux alliages d’aluminium, aux aciers inoxydables choisis dans la série 300 et aux alliages répertoriés dans le Tableau 5-1.

Zagotavljanje varnih proizvodov v vesoljski tehniki - Merila za izbiro materialov za izogibanje stresnim korozijskim razpokam

Ta standard obravnava naslednje procese splošne sheme materialov, mehanskih delov in procesov (MMPP) iz standarda ECSS-Q-ST-70:  • izbiro kovinskih zlitin, kjer imajo prednost odobreni podatkovni viri (preglednica 5.1 do 5.3), • potrebna je analiza kritičnosti za ugotavljanje, ali je potrebna ocena stresnega korozijskega pokanja (SCC). Ta standard določa merila, ki se uporabljajo pri izbiri materialov za vesoljska plovila in povezano opremo ter obrate, da se preprečijo odpovedi zaradi stresne korozije.  Namenjen je zagotavljanju splošnih meril, ki se uporabljajo pri izogibanju stresnim korozijskim razpokam, ki se začne med projektiranjem po zaslugi metodološke izbire materialov.  Ta dokument ne namerava zajeti vseh dejavnikov in meril, potrebnih za popolno izogibanje stresnim korozijskim razpokam v vseh zlitinah.  Merila, določena v tem standardu, se uporabljajo samo za zasnove za uporabo, ki vključuje pogoje izpostavljenosti, podobne preskusnim pogojem. Kar zadeva zvare, se ta standard uporablja za aluminijeve zlitine, izbrana nerjavna jekla iz skupine 300 in zlitine, navedene v preglednici 5.1. Ta standard se ne uporablja za navedene materiale, katerih obnašanje se razlikuje pri povišani temperaturi in v posebni kemikaliji. Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.
