| ASTM A662 |
ASTM A662 is a kind of Carbon Mn steel plate material used to fabric middle or low temperature pressure vessels. ASTM A662 is divided into three grades or levels: A662 Gr. A, A662 Gr. B and A662 Gr. C. A662 is in the standard specification ASTM A662 used for pressure vessel plates, carbon-manganese-silicon steel, for moderate and lower temperature service. ASTM A662 plates in thickness shall be normalized.
