SA537 Class 1 for LNG storage tank

SA537 Class 1 belongs to a type of American standard container steel plate, which is a heat-treated carbon-manganese-silicon steel plate for pressure vessels. It is suitable for fusion-welded pressure vessels and heat-treated carbon-manganese-silicon steel plates for structural use. SA537Cl1 steel plate is executed in accordance with the ASME standard SA-537/SA-537M, which is completely equivalent to the ASTM standard A537/A537M. SA537Cl1 steel plate needs to be delivered in a normalized state.

2.What are the performance advantages of SA537 Class 1？

High strength and high toughness: The tensile strength of SA537CL1 steel plate is ≥785MPa, and the yield strength is ≥590MPa, enabling it to maintain stable performance in extreme environments.
Fatigue and impact resistance: The steel plate has excellent fatigue and impact resistance, capable of withstanding long-term alternating loads and sudden impact loads to ensure the safe operation of boilers and pressure vessels.
Corrosion resistance: The steel plate has good corrosion resistance, able to resist various chemical corrosions and extend the service life of equipment.
Wear resistance and easy processing: The steel plate is wear-resistant and easy to process, reducing the difficulty and cost in the manufacturing process.

3.What are the typical applications of SA537 Class 1 for LNG storage tank？

Manufacturing boiler drums: The boiler drum is a key component in boilers, which needs to withstand high temperatures, high pressure, and erosion from steam. The high strength and high toughness of SA537CL1 steel plate make it an ideal material for manufacturing boiler drums.
Liquefied petroleum gas (LPG) cylinders: LPG cylinders need to withstand high pressure and erosion from corrosive media. The corrosion resistance and high strength of SA537CL1 steel plate enable it to meet these requirements.
High-pressure water pipes for hydropower stations: High-pressure water pipes in hydropower stations need to bear huge water pressure and impact loads. The fatigue resistance and impact resistance of SA537CL1 steel plate make it a preferred material for manufacturing high-pressure water pipes.

4.What is SA 537 Class 1 equivalent to?

The equivalent grades of the ASTM A537 Class 1 Carbon Steel Plates are the DIN 19Mn5 and SPV36 standards. All these plates are produced under the watchful eye of our experienced staff.
