321 stainless steel strip
| DESCRIPTION | Combines the excellent corrosion resistance of 304 stainless steel with the high temperature resistance of 309 stainless steel. It is more resistant to intergranular corrosion than 304 stainless steel due to its stabilization with titanium. Overall, 321 stainless steel is valued for its combination of corrosion resistance, heat resistance, and weldability, making it suitable for a variety of high-temperature and corrosive environments. | ||||||||

| POR CORROSION PICADURE | Los aceros inoxidables de la familia Cr-Ni se pueden emplear satisfactoriamente en medios cuya concentración en cloruros no sea superior a 200 ppm. | ||||||||
| INTERGRANULAR CORROSION | 321, al estar estabilizado con titanio, es menos susceptible a la corrosión intergranular que 304. Permite su uso continuado en el rango de temperaturas de sensibilización del material (5500C a 8500C) y en operaciones que conlleven un enfriamiento lento dentro de este rango de temperaturas | ||||||||
| CORROSION RESISTANCE | Los aceros inoxidables austeníticos de la familia Cr-Ni presentan unas buenas prestaciones de resistencia a la corrosión en un gran número de aplicaciones. Como ejemplo, estos aceros presentan velocidades de corrosión inferiores a 0,10 mm/año en los siguientes medios: -Ácido acético al 20% a 800C. -Ácido fórmico al 90% a 200C . -Ácido fosfórico al 20% a 600C. -Ácido nítrico al 20% a 500C. -Ácido sulfúrico al 90% a 200C. -Tolueno. -Leche. -Cerveza. -Zumo. -Vino. | ||||||||
| SURFACE CLEANING | Proper cleaning practices must be carried out on a regular basis to preserve the surface indefinitely and obtain the best performance of stainless steel. For proper cleaning, it is recommended to use neutral type water and soap, and apply it with a brush or brush that will not scratch the stainless steel. Always end the operation with a good water rinse to completely remove the cleaning products used. Chlorinated products should be avoided. If they must be used, contact must be minimized and then washed with plenty of water. | ||||||||
| SPECIFICATIONS | Los aceros inoxidables austeníticos 321 están incluidos en las principales normas internacionales. | ||||||||
| Pueden ser suministrados de acuerdo a los requerimientos de las normas EN, ASTM, ASME, AMS, QQS, MILS. | |||||||||
| Cumplen con los requisitos de las directivas europeas de: -Industria alimentaria, RE 1935/2004. -Cromo hexavalente, ROHS. -Aparatos eléctricos, ROHS. | |||||||||
Key properties of 321 stainless steel precision strip include:
High-temperature resistance: Suitable for prolonged use at high temperatures without losing its strength.
Corrosion resistance: Good resistance to oxidation and intergranular corrosion, especially in high-stress, high-temperature applications.
Good formability and weldability: It can be easily formed into various shapes and welded for different industrial uses.
