    Q : Pourquoi l'acier inoxydable est-il magn\u00e9tique ?
    \nR : L'acier inoxydable 304 appartient \u00e0 la cat\u00e9gorie des aciers inoxydables aust\u00e9nitiques. L'aust\u00e9nite est partiellement ou l\u00e9g\u00e8rement transform\u00e9e en martensite au cours du travail \u00e0 froid. La martensite est magn\u00e9tique, de sorte que l'acier inoxydable est non magn\u00e9tique ou faiblement magn\u00e9tique.
    \nQ : Comment identifier les produits en acier inoxydable authentiques ?
    \nR : 1. le test de la potion sp\u00e9ciale de l'acier inoxydable, s'il ne change pas de couleur, il s'agit d'un acier inoxydable authentique.
    \n2. Soutenir l'analyse de la composition chimique et l'analyse spectrale.
    \n3. Test de fum\u00e9e pour simuler l'environnement d'utilisation r\u00e9el.
    \nQ : Quels sont les aciers inoxydables les plus couramment utilis\u00e9s ?
    \nA : 1.SS201, adapt\u00e9 \u00e0 une utilisation en milieu sec, facile \u00e0 rouiller dans l'eau.
    \n2. SS304, environnement ext\u00e9rieur ou humide, forte r\u00e9sistance \u00e0 la corrosion et aux acides.
    \n3. SS316, molybd\u00e8ne ajout\u00e9, plus grande r\u00e9sistance \u00e0 la corrosion, particuli\u00e8rement adapt\u00e9 \u00e0 l'eau de mer et aux milieux chimiques.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    1. Duret\u00e9 \u00e9lev\u00e9e, pas de d\u00e9formation -- La duret\u00e9 de l'acier inoxydable est plus de 2 fois sup\u00e9rieure \u00e0 celle du cuivre, plus de 10 fois sup\u00e9rieure \u00e0 celle de l'aluminium, le traitement est difficile et le processus de production est compliqu\u00e9.
    \n2. durable et antirouille - fabriqu\u00e9 en acier inoxydable, la combinaison du chrome et du nickel cr\u00e9e une couche antioxydante \u00e0 la surface du mat\u00e9riau, qui joue le r\u00f4le de la rouille.
    \n3. respectueux de l'environnement, non toxique et non polluant --- L'acier inoxydable est reconnu comme un mat\u00e9riau sanitaire, s\u00fbr, non toxique et r\u00e9sistant aux acides et aux alcalis. Il n'est pas rejet\u00e9 dans la mer et ne pollue pas l'eau du robinet.
    \n4. Beaux, de haute qualit\u00e9, pratiques --- Les produits en acier inoxydable sont populaires dans le monde entier. La surface est argent\u00e9e et blanche. Apr\u00e8s dix ans d'utilisation, il ne rouillera jamais. Tant que vous l'essuyez avec de l'eau propre, il sera propre et beau, aussi brillant que neuf.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
