Kev faib tawm cov khoom siv
ASTM A333/A333M muaj ntau qib khoom siv, thiab cov tshuaj lom neeg ntawm txhua qib sib txawv:
1. Qib 1
Cov pa roj carbon (C): ≤0.30%
Manganese (Mn): 0.40-1.06%
Phosphorus (P): ≤0.025%
Sulfur (S): ≤0.025%
Silicon (Si): ≥0.10%
2. Qib 3
Cov ntsiab lus ntawm Nickel (Ni) yog li ntawm 3.5%, nrog rau qhov kub qis dua zoo dua
3. Qib 6
Cov pa roj carbon (C): ≤0.30%
Manganese (Mn): 0.29-1.06%
Phosphorus (P): ≤0.025%
Sulfur (S): ≤0.025%

Kev piav qhia ntxiv
1. Gr.6 yog qib siv dav tshaj plaws, tshwj xeeb tshaj yog rau cov chaw kub tsawg xws li LNG (-162 ℃)
2. Kev xaiv cov qib sib txawv nyob ntawm qhov kub tsim, cov yam ntxwv nruab nrab thiab kev txiav txim siab txog tus nqi
3. Txhua qib ntawm cov kav hlau raug kuaj xyuas qhov kub qis kom paub tseeb tias lawv muaj zog
4. Rau cov kav hlau welded, kev kho cua sov kom zoo yog qhov yuav tsum tau ua tom qab vuam kom rov qab tau cov khoom siv.
5. Thaum yuav khoom, yuav tsum xaiv cov khoom siv raws li qhov chaw siv, thiab daim ntawv pov thawj khoom siv thiab daim ntawv qhia kev xeem yuav tsum tau txheeb xyuas kom meej.
