The proportion and combination of these elements give SS321 stainless steel high temperature resistance, corrosion resistance and oxidation resistance 3.<\/p>\n<p>Strength and hardness: It has relatively high strength and hardness, which makes it perform well in some applications that require high strength and compressive resistance 1.<\/p>\n<p>Ductility and stress fracture resistance: Compared with 304 alloy, it has better ductility and stress fracture resistance, and has better creep stress resistance and stress fracture resistance1.<\/p>\n<p>Organization structure: As a duplex stainless steel, the organization structure of SS321 contains austenite phase and ferrite phase, which makes it have good corrosion resistance and strength1.<\/p>\n<p>Application field: It is commonly used in chemical equipment, petrochemical equipment, food industry equipment and other fields under high temperature. It can also be used in aircraft, exhaust pipes, boiler drums, etc.; it is also widely used in chemical, petroleum and pharmaceutical fields.<\/p>\n<p>&nbsp;<\/p>\n<table>\n<tbody>\n<tr>\n<td>Product \u00a0 Name<\/td>\n<td>Barre en acier inoxydable<\/td>\n<\/tr>\n<tr>\n<td>Standard<\/td>\n<td>ASTM,JIS,DIN,GB,AISI,DIN,EN<\/td>\n<\/tr>\n<tr>\n<td>Mat\u00e9riau<\/td>\n<td>201, 202, 301, 301L, 304, 304L, 316, 316L, 321, 310S, 904L, 410, 420J2, 430, 2205, 2507, 321H, 347, 347H, 403, 405, 409, 420, 430, 631, 904L, 305, 301L, 317, 317L, 309, 309S 310<\/td>\n<\/tr>\n<tr>\n<td>Technique<\/td>\n<td>Etir\u00e9 \u00e0 froid, lamin\u00e9 \u00e0 chaud, lamin\u00e9 \u00e0 froid et autres.<\/td>\n<\/tr>\n<tr>\n<td>Diameter<\/td>\n<td>6-12mm ou personnalisable<\/td>\n<\/tr>\n<tr>\n<td>Longueur<\/td>\n<td>1000 &#8211; 6000mm or Customizable<\/td>\n<\/tr>\n<tr>\n<td>Traitement de surface<\/td>\n<td>BA\/2B\/NO.1\/NO.3\/NO.4\/8K\/HL\/2D\/1D<\/td>\n<\/tr>\n<tr>\n<td>Origine<\/td>\n<td>Chine<\/td>\n<\/tr>\n<tr>\n<td>Code SH<\/td>\n<td>7220204000<\/td>\n<\/tr>\n<tr>\n<td>D\u00e9lai de livraison<\/td>\n<td>{D\u00e9lai de livraison}<\/td>\n<\/tr>\n<tr>\n<td>Service apr\u00e8s-vente<\/td>\n<td>24 heures en ligne<\/td>\n<\/tr>\n<tr>\n<td>Capacit\u00e9 de production<\/td>\n<td>{Capacit\u00e9 de production}<\/td>\n<\/tr>\n<tr>\n<td>Conditions de prix<\/td>\n<td>EXW, FOB, CIF, CRF, CNF or \u00a0 others<\/td>\n<\/tr>\n<tr>\n<td>Port de chargement<\/td>\n<td>{Port}<\/td>\n<\/tr>\n<tr>\n<td>D\u00e9lai de paiement<\/td>\n<td>TT, LC, Cash, Paypal, DP, DA, \u00a0 Western Union or Others.<\/td>\n<\/tr>\n<tr>\n<td rowspan=\"3\">Application<\/td>\n<td>1.
