Chome Moly steel plate, formally known as Chrome Molybdenum, is usually sold as ASTM A387 orASME SA387. A387 is alloy steel plate that is designed for use in pressure vessels, process vessels and boilers operating at high temperatures.There are ten grades of Chromium Molybdenum steel plate (A387) 2, 12, 11, 22, 22L, 21, 21L, 9 and 91 specified by ASTM/ASME, though A387 grades 2, 21, 21L and 22L are generally not available at steel stockholders and have to be ordered in mill quantities. Chrome moly grades 9 and 91 are also less popular and are often difficult to obtain
