EN 10216-1 P235 minangka bahan pipa baja umum. Miturut standar kasebut, dipérang dadi rong kelas: TR1 lan TR2. TR1 ora mbutuhake perawatan panas, dene TR2 mbutuhake perawatan normalisasi. TR2 kira-kira padha karo TR2 saka segi komposisi kimia, nanging mbutuhake unsur tambahan; TR1 lan TR2 kira-kira padha karo sifat mekanik. Bedane yaiku TR1 ora mbutuhake tes dampak, dene TR2 mbutuhake tes dampak 0°C. Syarat inspeksi kanggo pipa rampung uga beda kanggo TR1 lan TR2. TR1 mung mbutuhake pemeriksaan rutin, dene TR2 mbutuhake pemeriksaan khusus (tes impact tambahan).
Yen ora ana syarat khusus, EN10216 P235 TR1 paling umum digunakake, padha Cina baja kelas GB / T8163 20 # utawa GB / t8162 Q235C, lan bisa diganti kanggo saben liyane.

a.Saliyane kelas Q345A lan Q345B, baja kudu ngemot paling ora siji unsur gandum olahan Al, Nb, V, lan Ti. Miturut kabutuhan, supplier bisa nambah siji utawa luwih unsur gandum olahan. Nilai maksimum kudu kaya sing kasebut ing tabel. Yen digabungake, Nb + V + Ti ora luwih saka 0,22%b. Kanggo kelas Q345, Q390, Q420 lan Q46O, Mo + Cr ora luwih saka 0,30%c. Nalika Cr lan Ni saben kelas digunakake minangka unsur residual, isi Cr lan Ni ngirim ora luwih saka 0,30%; yen perlu ditambahake, isi kasebut kudu nyukupi syarat ing tabel utawa ditemtokake dening supplier lan panuku liwat konsultasi.d. Yen supplier bisa mesthekake yen isi nitrogen meets syarat ing tabel, analisis isi nitrogen bisa uga ora dileksanakake. Yen Al, Nb, V, Ti lan unsur paduan liyane kanthi fiksasi nitrogen ditambahake ing baja, isi nitrogen ora diwatesi. Isi fiksasi nitrogen kudu ditemtokake ing sertifikat kualitas.e. Nalika nggunakake aluminium lengkap, total isi aluminium Alt ≥ 0020%. |

a. Range imbuhan sing diidini saka suhu perawatan panas sing kadhaptar ing tabel: quenching ± 15 ℃, tempering suhu kurang ± 20 ℃, lemah tempering suhu dhuwur 50 ℃.b. Ing tes tensile, conto transversal utawa longitudinal bisa dijupuk. Yen ora setuju, sampel longitudinal digunakake minangka basis kanggo arbitrase.c. Baja sing ngemot boron bisa dinormalisasi sadurunge quenching, lan suhu normalisasi ora kudu luwih dhuwur tinimbang suhu quenching.d. Pangiriman miturut sakumpulan data sing ditemtokake dening panyuwun. Yen panjaluk durung nemtokake, pangiriman bisa ditindakake miturut data apa wae. e. Ing quenching pisanan saka baja titanium karo Ming Meng bisa diganti dening normalizing. f. Isothermal quenching ing 280 C ~ 320 C. g. Ing test tensile, yen Rel ora bisa diukur, Rp0,2 bisa diukur tinimbang Rel. |
