A36 Steel Plate
A36 steel general information
The A36 steel specification was first issued in 1960. And today, engineers specify ASTM A36 for more structural steel fabrications than any other type of plate. Consequently, this product is the most purchased hot-roll steel plate in the world and the least expensive of the commercial carbon steels. The heat ability creates very good welding properties, and the 36 KSI yield strength makes it acceptable for most applications. Furthermore, A36 is considered a mild steel due to it’s relatively moderate hardness.
A-36 is a structural-quality mild carbon steel used in general construction applications, including bolted or welded construction of buildings, bridges and common machine parts to name a few.
Common Uses of A36 Steel Plate
Common uses of A36 include shim plates, Gusset plates, bridge plates, bearing plates, robot bases and column base plates. Likewise, we typically cut A36 for press parallels, press platens, tooling plates, machine plates, machine frames and pedestals, steel table tops, base plates, mold & die, machine mounting plates, etc.
