不銹鋼不會產生腐蝕、點蝕、銹蝕或磨損。不銹鋼還是建筑用金屬材料中強度最高的材料之一。由于不銹鋼具有良好的耐腐蝕性，所以它能使結構部件永久地保持工程設計的完整性。含鉻不銹鋼還集機械強度和高延伸性于一身，易于部件的加工制造，可滿足建筑師和結構設計人員的需要。不銹鋼常按組織狀態分為：馬氏體鋼、鐵素體鋼、奧氏體鋼等。另外，可按成分分為：鉻不銹鋼、鉻鎳不銹鋼和鉻錳氮不銹鋼等。　 　　1、鐵素體不銹鋼：含鉻12%～30%。其耐蝕性、韌性和可焊性隨含鉻量的增加而提高，耐氯化物應力腐蝕性能優于其他種類不銹鋼。 　2、奧氏體不銹鋼：含鉻大于18%，還含有 8%左右的鎳及少量鉬、鈦、氮等元素。綜合性能好，可耐多種介質腐蝕。3、奧氏體 - 鐵素體雙相不銹鋼：兼有奧氏體和鐵素體不銹鋼的優點，并具有超塑性。 　4、馬氏體不銹鋼：強度高，但塑性和可焊性較差。1CR13 2CR13 3CR13 4CR13 420 420J2 1CR17 12Cr17Mn6Ni5N 12Cr18Mn9Ni5N 12Cr17Ni7 12Cr18Ni9 Y12Cr18Ni9 Y12Cr18Ni9Se 06Cr19Ni10 022Cr19Ni10 06Cr19Ni10N 06Cr19Ni9NbN 022Cr19Ni10N 10Cr18Ni12 06Cr23nI13 06Cr25Ni20 06Cr17Ni12Mo2 06CR17NI12MO3TI 022CR17NI12MO2 06CR17NI12MO2N 022CR17NI12MO2N 06CR18NI12MO2CU2 022CR18NI14MO2CU2 06CR19NI13MO3 022CR25NI22MO2N 022CR19NI13MO4N 022CR19NI13MO3 03CR18NI16MO5 07CR18NI11TI 06CR18NI11TI 06CR18NI11NB 06CR18NI9CU3 06CR18NI3SI4 022CR22NI5MO3N 022CR25NI6MO2N 03CR25NI6MO3CU2N 06CR13AL 022CR12 10CR17 Y10CR17 10CR17MO 088CR30MO2 088CR27MO 12CR12 06CR13 12CR13 13CR13MO Y12CR13 20CR13 30CR13 40CR13 Y30CR13 14CR17NI2 68CR17 85CR17 108CR17 Y108CR17 05CR17NI4CU4NB 07CR17NI7AL 07CR15NI7MO2AL S35350 S35450 S30110 S30210 S30317 S30327 S30408 S30403 S30458 S30478 S30453 S30510 S30908 S31008 S31608 S31668 S31603 S31658 S31653 S31688 S31683 S31708 S31053 S31753 S31703 S31794 S32169 S32168 S34778 S30488 S34148 S22253 S22553 S25554 S11348 S11203 S11710 S11717 S11790 S13091 S12791 S40310 S41008 S41010 S45710 S41617 S42020 S42030 S42040 S42037 S43110 S44070 S44080 S44096 S44097 S51740 S51770 S51570 法：X2CRNI12 X2CRTI12 X6CRNITI12 X6CR13 X6CR17 X3CRTI17 X3CRNB17 X6CRMO17-1 X2CRMOTI18-2 X1CRNB15 X5CRNIMOTI15-2 X2CRTI17 X2CRMOTI17-1 X6CRNI17-1 X6CRMONB 17-1 X2CRNBZR17 X2CRTINB18 X2CRMOTI29-4 X12CR13 X20CR13 X30CR13 X46CR13 X50CRMOV15 X39CRMO17-1 X3CRNIMO13-4 X4CRNIMO16-5-1 X15CR13 X38CRMO14 X55CRMO14 1.4003 1.4512 1.4516 1.4000 1.4002 1.4016 1.4510 1.4511 1.4113 1.4521 1.4595 1.4589 1.4520 1.4513 1.4017 1.4526 1.4590 1.4509 1.4592 1.4006 1.4021 1.4028 1.4031 1.4034 1.4116 1.4122 1.4313 1.4418 1.4024 1.4419 1.4110 X5CRNICUNB16-4 X7CRNIAL17-7 X1CRNIMOCU12-5-2 X1CRNIMOCU12-7-3 X10CRNI18-7 X2CRNI18-7 X2CRNI18-9 X2RNI19-11 X2CRNIN18-10 X5CRNI18-10 X8CRNIS18-9 X6CRITI18-10 X4CRNI18-12 X2CRNIMO17-12-2 X2CRNIMON17-11-2 X5CRNIMO17-12-2 X6CRNIMOTI17-12-2 X2CRNIMO17-12-3 X2CRNIMO18-14-3 X2CRNIMON17-13-5 X1NICRMOCU25-20-5 X1CRNIMOCUN24-22-8 X1CRNIMOCUNW24-22-6 X2CRNIMNMON25-18-6-5 X5CRNI17-7 X5CRNIN19-9 X8CRMNCUNB17-8-3 X11CRNIMNN19-8-6 X1CRNI25-21 X6CRNINB18-10 X1CRNIMON25-22-2 X6CRNIMONB17-12-2 X2CRNIMON17-13-3 X3CRNIMO17-13-3 1.4542 1.4568 1.4422 1.4423 1.4310 1.4318 1.4307 1.4306 1.4311 1.4301 1.4305 1.4541 1.4303 1.4404 1.4406 1.4401 1.4571 1.4432 1.4435 1.4439 1.4539 1.4652 1.4659 1.4565 1.4319 1.4315 1.4597 1.4369 1.4335 1.4550 1.4466 1.4580 1.4429 1.4436 X2CRNIMON18-12-4 X2CRNIMO18-15-4 X1CRNISI18-15-4 X12CRMNNIN17-7-5 X2CRMNNIN17-7-5 X12CRMNNIN18-9-5 X1NICRMOCU31-27-4 X1CRNIMOCUN20-18-7 X1NICRMOCUN25-20-7 X2CRNIN23-4 X2CRNI MON22-5-3 X2CRNICUN23-4 X2CRNIMON29-7-2 X2CRNIMOSI18-5-3 X2CRNIMOCUN25-6-3 X2CRNIMON25-7-4 X2CRNIMOCUWN25-7-4 1.4434 1.4438 1.4361 1.4372 1.4271 1.4373 1.4563 1.4537 1.4547 1.4529 1.4362 1.4462 1.4655 1.4477 1.4424 1.4507 1.4410 1.4501 德：X6CR13 X7CR14 X6CRAL13 X2CRNI12 X2CR11 X12CRS13 X12CR13 X6CR17 X20CR13 X15CR13 X30CR13 X39CR13 X46CR13 X65CR13 X17CRNI16-2 X14CRMOS17 X6CRMOS17 X70CRMO15 X55CRMO14 X110CRMOV15 X90CRMOV18 X6CRMO17-1 X50CRMOV15 X38CRMOV15 X20CRMO13 X39CRMO17-1 X105CRMO17 X5CRNI18-10 X4CRNI18-12 X8CRNIS18-9 X2CRNI19-11 X10CRNI18-8 X2CRNIN18-10 X3CRNI13-4 X2CRNIN18-7 X1CRNI25-21 X1CRNISI18-15-4 X2CRNIN23-4 X5CRNIMO17-12-2 X2CRNIMO17-12-2 X2CRNIMO17-13-2 X2CRNIMON17-11-2 X4CRNIMO16-5-1 X2CRNIMO18-14-3 X3CRNIMO17-13-3 X5CRNIMO17-13-3 X2CRNIMO18-15-4 X2CRNIMON17-13-5 X3CRNIMO27-5-2 X2CRNIMON25-5-3 X1CRNIMON25-25-2 X1CRNIMON25-22-2 X4NICRMOCUNB20-18-2 X5NICRMOCUTI20-18 X2CRTINB18 X3CRTI17 X3CRNB17 X2CRTI12 X6CRTI12 X2CRMOTI18-2 X1NICRMOCUN25-20-7 X1CRNIMOAL15-7-2 X90CRCOMOV17 X1NICRMOCU25-20-5 X6CRNITI18-10 X5CRNICUNB16-4 X6CRNIBN18-10
