SA553 type I steel plate executive standard: SA-553/SA-553M (completely equivalent to ASTM standard A553/A553M-15)P295GH grade steel material, SA553 Type I steel plate application scope: SA553M type I steel plate is mainly used to manufacture liquefied natural gas (LNG) storage tanks and transport ships. Its service temperature can reach -196℃. p295gh grade steel material, SA553 type I steel plate has high strength, excellent low temperature toughness and good welding performance. It is a material with good toughness used in cryogenic environment.

As the thickness and hardness of p295gh grade steel material increase, the tendency to crack at the cutting edge increases. In order to prevent the p295gh grade steel material from cutting cracks, preheating should be carried out before p295gh grade steel material cutting. Special attention should be paid to preheating to make the entire p295gh grade steel material interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole p295gh grade steel material cannot be preheated, the partial preheating method can be used instead.

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in p295gh grade steel material etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.
