SA515Gr60 steel implementation standards: ASTM/ASME American Institute of materials and inspection standards, this standard is mainly used to improve notch toughness, important welding pressure vessel steel plate.
SA515Gr60 steel delivery status: according to the performance and user needs, the steel plate can be hot-rolled, controlled rolling, normalizing, annealing, tempering, normalizing + tempering, quenching and tempering and other delivery;
SA515Gr60 steel flaw detection and thickness direction performance: can produce additional inspection requirements and Z15-Z35 anti tear (thickness direction performance) steel plate, also can press ASTM, A770 and other standards to provide Z performance steel plate. Used to make all kinds of alloy structural parts and their components, such as power plant boiler, super heater header, and large diameter pipe plate structure.
SA515Gr60 steel application scope: widely used in petroleum, chemical industry, power plants, boilers and other industries, for the production of reactor, heat exchanger, separator, tank, oil tank, liquefied gas, nuclear reactor pressure vessel, boiler, liquefied petroleum gas cylinders, hydropower station high pressure pipes, turbine volute equipment and components. Steel sheet for containers must be made to the container under pressure with different intensity, the general pressure is 31.4MPa or higher, often working temperature between -20 DEG -450 DEG C, there are less than -20, according to the requirements of container working conditions and processing technology of steel plate must have good cold bending and welding performance of plastic and good toughness, strength of the high-temperature short or long-term strength, in order to make the container can withstand higher pressure, reduce the structure weight, container plate material except for high quality carbon steel, most of the low alloy structure steel material. SA516Gr60 thickness less than 1.5in (40mm) steel usually supply to rolling state, steel plate can be eliminated by normalizing or stress, or normalizing and tempering, the thickness of SA516Gr60, 1.5in. (40mm) steel plate should be normalized. If approved by the buyer, the SA516Gr55, SA516Gr60, and
SA516Gr70 allow greater cooling rates greater than those in the air to improve toughness, but the steel plate is then tempered within 1100-1300 degrees F (595-705 DEG C).
