Catatan:Kelas baja khusus juga tersedia, sesuai permintaan pelanggan.
aRm: kekuatan tarik; ReH: kekuatan hasil atas; A: perpanjangan setelah patah
b 1Mpa = 1N/mm2
c Tergantung pada tingkat kerja dingin dalam melewati finishing kekuatan hasil mungkin hampir setinggi kekuatan tarik.
Untuk tujuan perhitungan, hubungan berikut direkomendasikan:
untuk kondisi pengiriman +C: ReH ≥0,8 Rm
untuk kondisi pengiriman +LC: ReH ≥0,7 Rm
d Untuk tujuan perhitungan, relasi berikut dianjurkan:ReH≥0,5Rm
e Untuk tabung dengan diameter luar ≤30mm dan ketebalan dinding ≤3mm, nilai minimal ReH adalah 10Mpa lebih rendah dari nilai yang diberikan dalam tabel ini
f Untuk tabung dengan diameter luar > 160 mm: ReH≥420Mpa
