304 / 304L Stainless Steel Seamless Tubing
Pambuka produk
Alloys 304 (S30400) lan 304L (S30403) stainless steels variasi saka 18 persen kromium - 8 persen nikel austenitic alloy, alloy paling menowo lan paling kerep digunakake ing kulawarga stainless steel. Baja tahan karat 304/L nduweni sifat fabrikasi sing apik. Malleability ngidini gampang dibentuk kanggo flaring, mlengkung lan coiling. Machinability apik lan isi belerang kurang dipun promosiaken weldability banget ing aplikasi mbutuhake iku.
Kekuwatan dhuwur, tahan korosi sing apik lan isi karbon sing diminimalisir nggawe Alloy 304 lan 304L Stainless Steels migunani kanggo aplikasi ing ngendi welding dibutuhake. Panggunaan kalebu cetakan lan trim arsitektur, komponen sing dilas saka bahan kimia, tekstil, kertas, peralatan pangolahan industri farmasi lan kimia.
Kauntungan liyane yaiku resistensi kanggo oksidasi, bisa dibentuk banget, gampang nggawe lan ngresiki, rasio kekuatan kanggo bobot sing apik lan ketangguhan sing apik ing suhu kriogenik Kanggo lingkungan sing korosif banget, konten Tipe 304L sing luwih murah luwih disenengi amarga kekebalan sing luwih gedhe kanggo korosi intergranular.
Baja tahan karat tipe 304L minangka versi karbon ekstra rendah saka baja 304paduan. Isi karbon sing luwih murah ing 304L nyilikake udan karbida sing mbebayani utawa mbebayani minangka asil saka welding. 304L bisa, mulane, digunakake "minangka gandheng" ing lingkungan karat abot, lan ngilangake perlu kanggo annealing.
Kelas iki nduweni sifat mekanik sing rada luwih murah tinimbang kelas 304 standar, nanging isih akeh digunakake amarga versatility. Kaya baja tahan karat Tipe 304, umume digunakake ing nggawe bir lan nggawe anggur, nanging uga kanggo tujuan ngluwihi industri panganan kayata ing wadhah kimia, pertambangan, lan konstruksi. Iku becik kanggo nggunakake ing bagean logam kayata perkakas lan bolts sing kapapar banyu uyah.
