The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many A514 grade E quenched and tempered steel products have been exported to the Middle East, India, Southeast Asia and Europe and America.
Pressure vessel steel SA204GrA, SA204GrB, SA204GrC sheet delivery status: normalized rolling, maybe normalized, or other heat treatment methods may be negotiated with users for delivery. Generally, the thickness of the A514 grade E quenched and tempered steel, ASME SA204 pressure vessel steel plate is ≤40mm, and it is generally delivered in the rolled state, and the SA204GrA steel plate of more than 40mm can be delivered in the normalized heat treatment state.
Different form A514 grade E quenched and tempered steel, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.
The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in A514 grade E quenched and tempered steel 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.
