CSA G40.21 50W / 50A
In addition to the 44W Chapel Steel also stocks the higher strength Canadian steel plate in grades G40.21 50W and G40.21 50A . 50A has a higher alloy content than 50W which contributes to its weathering ability. Both 50W and 50A are sometimes referred to with their metric designations of 350W and 350A. When referenced with a “T”, such as 50WT, this indicates that charpy tests are required. When Charpy tests are required, the category will be indicated. Value of categories are described below in mechanical properties.
