ASTM A202 Alloy Steel for Pressure Vessel

ASTM A202 Alloy Steel for Pressure Vessel

ASTM A202 steel(ASME SA202 ) is a kind of chromium-manganese-silicon alloy steel plates, intended particularly for welded boilers and other pressure vessels. There are two quality steel under A202 standard: A202 Grade A and A202 Grade B.

ASTM A202 steel(ASME SA202 ) is a kind of chromium-manganese-silicon alloy steel plates, intended particularly for welded boilers and other pressure vessels. There are two quality steel under A202 standard: A202 Grade A and A202 Grade B.
The properties of ASTM A202 steel include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare ASTM A202 steel to: wrought alloy steels in the same category (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
