What is the maximum ASTM A612M steel plate thickness

ASTM A612M steel plate is PVQ steel, otherwise known as "pressure vessel quality steel". That means, ASTM A612M steel plate is steel specially intended for pressure vessels, which require higher standards for chemical composition and material properties because of its unique end-use. The maximum ASTM A612M steel plate thickness is 25mm [1 inch].

ASTM A612M steel plate chemical composition:

ASTM A612M steel plate mechanical properties:

Thickness	0.5in [12.5mm] and under	Over 0.5in. to 1in.[Over 12.5 to 25mm]
Tensile strength, ksi [Mpa]	83-150 [570-725]	81-101 [560-695]
Yield strength,min,ksi [Mpa]	50 [345]	50 [345]
Elongation in 8in. [200mm], min, %	16	16
Elongation in 2in. [50mm], min, %	22	22

ASTM A612M steel plate thickness is not heavy. The usual delivery state of ASTM A612M steel plate is as-rolled. However, ASTM A612M steel plate can be ordered normalized or stress relieved, or both, as well. ASTM A612M steel plate usually serve at moderate and lower temperatures.
