A333 GR. 7 Alloy steel yeeb nkab
ASTM A333 GR.7 seamless steel yeeb nkab yog qib ASTM A333.
Cov khoom muaj pes tsawg leeg ntawm A333 GR.7 alloy steel yeeb nkab suav nrog carbon, manganese, phosphorus, sulfur, silicon, npib tsib xee, chromium thiab molybdenum, thiab lwm yam los txhim kho corrosion kuj ntawm ASTM A333 GR.7 tsis tshua muaj kub steel yeeb nkab. Tsis tas li ntawd, ASTM A333 GR.7 tsis tshua muaj kub seamless steel yeeb nkab tuaj yeem tiv taus qhov kub thiab txias ntawm -45 degree ~ -195 degree . Yog li ntawd, A333 GR.7 seamless alloy steel yeeb nkab tau dhau los ua cov yeeb nkab uas muaj qhov kub thiab txias hauv kev lag luam roj thiab roj.
