Ringkesan Pipa Stainless Steel 321
Minangka versi modifikasi saka SS304, stainless steel 321 (SS321) punika stabil austenitic stainless steel karo tambahan titanium saka ing paling 5 kaping isi karbon.Penambahan titanium nyuda utawa nyegah sensitisasi udan karbida sajrone welding lan ing layanan ing kisaran suhu 425-815 ° C.Uga nambah sawetara sifat ing suhu sing luwih dhuwur.SS321 nyedhiyakake ketahanan sing luar biasa kanggo oksidasi lan karat lan nduweni kekuatan creep sing apik.Iki digunakake utamane ing peralatan kilang minyak, pipa prau tekanan, pemanas super sumringah, bellews, lan peralatan perawatan panas suhu dhuwur.

Kekuwatan Kelelahan saka 321 Tabung Stainless Steel
Ing aplikasi dinamis, kekuatan lemes uga penting kanggo nimbang.Lan ing bab iki 321 SS duwe kauntungan tipis saka 304 SS.Watesan lemes utawa toleransi (kekuwatan ing mlengkung) saka baja tahan karat austenitik ing kondisi anil kira-kira setengah saka kekuatan tarik.

| 304L | 68 ksi | 34 ksi |
| 304 | 70 ksi | 35 ksi |
| 321 | 76 ksi | 38 ksi |
Weldability saka 321 Stainless Steel Tube
SS321 lan TP321 wis weldability banget, ora preheating dibutuhake.Bahan ngisi kudu duwe komposisi sing padha nanging isi aloi sing luwih dhuwur.Cairan retak ing zona kena pengaruh panas: input energi kurang.Ukuran butir halus.Ferrite ≥ 5%.
Logam pangisi sing disaranake yaiku SS 321, 347, lan 348. Elektroda yaiku E347 utawa E308L [suhu layanan <370 °C (700 °F)].
Aplikasi saka 321 Stainless Steel Tube
Tipe 321, 321H lan TP321 bisa digunakake ing panggonan ing ngendi perawatan solusi sawise welding ora bisa, kayata saluran uap lan pipa superheater lan sistem exhaust ing mesin reciprocating lan turbin gas kanthi suhu antara 425 nganti 870 °C (800 nganti 1600 °). F).Lan garis injeksi bahan bakar lan sistem hidrolik kanggo pesawat lan kendaraan aerospace.
