ASTM (American Society for Testing and Materials) muaj ob peb yam tshwj xeeb rau cov kav dej carbon steel. Qhov tshwj xeeb ASTM tus qauv rau cov pa roj carbon steel kav nyob ntawm ntau yam xws li hom yeeb nkab, nws qhov ntev, thiab nws daim ntawv thov. Nov yog qee cov qauv siv ASTM rau carbon steel kav:
1. ASTM A53 / A53M: Standard Specification rau Yeeb Nkab, Hlau, Dub thiab Kub-dipped, Zinc-Coated, Welded thiab Seamless. Qhov kev qhia tshwj xeeb no suav nrog ob qho tib si welded thiab seamless carbon steel kav siv rau kev sib txawv ntawm cov kua dej, gases, thiab cua.
2. ASTM A106 / A106M: Txheem Specification rau Seamless Carbon Steel Pipe rau Kev Pabcuam Kub Kub. Qhov kev qhia tshwj xeeb no suav nrog seamless carbon steel kav npaj rau kev siv kub kub, xws li cov chaw tsim hluav taws xob, refineries, thiab boilers.
3. ASTM A333 / A333M: Txheem Specification rau Seamless thiab Welded Steel Yeeb Nkab rau Kev Pabcuam Kub Kub. Qhov kev qhia tshwj xeeb no suav nrog ob qho tib si seamless thiab welded carbon steel kav siv nyob rau hauv qhov chaw qis, xws li cov ntawv thov cryogenic.
4. ASTM A1065/A1065M: Standard Specification for Cold-Formed Electric-Fusion (Arc) Welded High-Strength Low-Alloy Structural Tubing in Shapes, with 50 ksi [345 MPa] Yam tsawg kawg nkaus Yield Point. Txawm hais tias tsis yog tshwj xeeb rau carbon steel kav, tus qauv no npog qhov txias-tsim hluav taws xob-fusion welded high-strength low-alloy structural tubing, uas tuaj yeem suav nrog carbon steel.
Cov no tsuas yog qee qhov piv txwv ntawm ASTM cov qauv ntsig txog carbon steel kav. Nws yog ib qho tseem ceeb rau kev sab laj tus qauv tshwj xeeb uas ua raws li koj cov kev xav tau, xav txog yam xws li cov yeeb nkab hom, qib, qhov ntev, thiab daim ntawv thov.
