ASTM A335 yeeb nkab yog seamless ferritic alloy steel yeeb nkab siv rau hauv qhov kub thiab txias.
Cov kav hlau uas tau teev tseg raws li ASTM A335 tus qauv yuav tsum tsim nyog rau kev khoov, flanging (vanstoning) thiab lwm yam kev ua haujlwm, nrog rau fusion vuam. Cov yeeb nkab steel no qee zaum hu ua "P-qib", nrog qib P11, P22, thiab P91 yog qhov feem ntau siv thiab feem ntau siv hauv kev lag luam hluav taws xob thiab kev lag luam petrochemical. Qib P5 thiab P9 feem ntau yog siv nyob rau hauv refineries. Qib 1 yog qhov zoo tshaj plaws rau kev pabcuam kub tsis tshua muaj, thiab qib 2 yog qhov zoo tshaj plaws rau kev pabcuam kub. Qib 11 feem ntau yog siv rau hauv cov ntawv thov uas xav tau kev tiv thaiv corrosion lossis kub siab txog 500℃F (260 degree).
