ASTM A832 Gr. 21V Abstract :
ASTM A832 Gr. 21V 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.
Shanghai Katalor Enterprises Co., Ltd are situated on beautiful city ~ Shanghai. Our company not only supply large quantity steel products, also can offer the various kinds of processing. Our advantage is export steel plate, coil, pipe/tube, stainless steel and so on, if you have any requirements of those products, please be free to contact us.
