ASTM A832 Gr. 22V covers the specific chromium-molybdenum-vanadium alloy steel plates intended primarily for the fabrication of welded pressure vessels. The steel shall be killed and shall conform to the fine grain size requirement. All plates shall undergo normalization and tempering. Heat and product analyses shall be conducted and the steel shall conform to the prescribed chemical composition in carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, vanadium, titanium, boron, and copper. Tension and notch toughness testing shall be performed on the material and shall meet the required mechanical properties such as tensile strength, yield strength, and elongation.
ASTM A832 Gr. 22V is a kind of Cr-Mo-V alloy steel plates material used to fabric pressure vessels. A832 is divided into three grades or levels : A832 Grade 21V, A832 Grade 22V, A832 Grade 23V.
Standard: ASTM A-832/A-832M
Dimension range : 3mm -500mm * 1000mm-4000mm * 1000mm-18000mm
