Gli acciai austenitici sono delle particolari leghe al Cromo-Nichel che oltre ad avere un contenuto di carbonio generalmente molto basso, al di sotto dello 0,1 %, si distinguono per tenori di cromo che variano fra il 16-26 % e di nichel che \u00e8 presente in ragione del 6- 22 %.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>

AISI 201 <\/strong><\/p>\n

(X12CrMnNiN17-7-5 \u2013 EN 1.4372)<\/em><\/td>\n

\n
E’ un acciaio inossidabile austenitico al Cromo con percentuali di Nichel molto basse ma con caratteristiche simili all\u2019Aisi 304. La bassa percentuale di Nichel e\u2019 compensata dal Manganese.<\/div>\n<\/td>\n<\/tr>\n
AISI 304<\/strong><\/p>\n

(X5CrNi18-10 – EN 1.4301)<\/em><\/td>\n

\n
E’ ritenuto l’acciaio inossidabile per eccellenza ed e\u2019 resistente alla corrosione in generale. E’ adatto per ambienti esterni non molto aggressivi.<\/div>\n<\/td>\n<\/tr>\n
AISI 304L <\/strong><\/p>\n

(X2CrNi18-9 \u2013 EN 1.4307) <\/em><\/td>\n

\n
E’ derivato dall’AISI 304 per\u00f2 con un contenuto di carbonio inferiore che gli permette una migliore saldabilit\u00e0.<\/div>\n<\/td>\n<\/tr>\n
AISI 316 <\/strong><\/p>\n

( X5CrNiMo17-12-2 \u2013 EN 1.4401) <\/em><\/td>\n

\n
E’ molto piu\u2019 resistente alla corrosione rispetto agli AISI 304, grazie alla presenza del Molibdeno. E’ particolarmente adatto a tutte le applicazioni in ambienti esterni tipo le zone costiere o industriali con forti presenze saline.<\/div>\n<\/td>\n<\/tr>\n
AISI 316L <\/strong><\/p>\n

(X2CrNiMo17-12-2 \u2013 EN 1.4404) <\/em><\/td>\n

\n
E’ derivato dall’AISI 316, ha le stesse caratteristiche di resistenza alla corrosione, ma un contenuto di carbonio inferiore, che gli permette una migliore saldabilit\u00e0.<\/div>\n<\/td>\n<\/tr>\n
AISI 310 S <\/strong><\/p>\n

(X8CrNi 25-21 \u2013 EN 1.4845) <\/em><\/td>\n

\n
E conosciuto anche come acciaio refrattario per la sua capacit\u00e0 di resistere all’ossidazione a temperature molto elevate.<\/div>\n<\/td>\n<\/tr>\n
AISI 321 <\/strong><\/p>\n

(X6CrNiTi18-10 \u2013 EN 1.4541) <\/em><\/td>\n

\n
Acciaio stabilizzato al titanio che lo rende insensibile alla corrosione intercristallina anche dopo al saldatura. Notevole resistenza alla corrosione. Fino alla temperatura di 200\/300\u00b0C mantiene inalterate le proprie caratteristiche meccaniche.<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>
