ASTM A537 Class 1 steel plate is heat-treated steel and in normalized state. As a consequence, ASTM A537 Class 1 steel plate displays greater yield and tensile strength than the more standard ASTM A516 steel. ASTM A537 Class 1 steel plate is ideal for both boilers and pressure vessels applications, and is widely used in the oil, gas and petrochemical industry.

ASTM A537 Class 1 steel plate shows good cold forming performance. For A537 Class 1 steel plate welding, special consumables and welding methods are needed for avoiding harmful effects of metal structure. The typical applications of ASTM A537 Class 1 steel plates are API 650 and API 620 storage tanks, pressure vessels designed for moderate and lower-temperature service, requiring excellent notch toughness.
