A515GR60 steel provides HIC+SSC testing. Implementation standards: ASTM/ASME American Institute of materials and inspection standards, this standard is mainly used to improve the gap toughness, important welding pressure vessel steel plate.
A515GR60 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.
Heat treatment: 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).
A515GR60 steel tensile strength:
Grade U.S (SI) tensile strength Ksi (MPa)
55 (380) 55-75 (380-515)
60 (415) 60-80 (415-550)
65 (450) 65-85 (450-585)
70 (485) 70-90 (485-620)
A516Gr70N steel meets the requirements of (ASME) ASTM A516/A516M standard, and satisfies the needs of high sulfur content and hydrogen gas, reduces the corrosion of sulfur and hydrogen, reduces the overhaul of equipment and increases the service life of equipment. The plate has the characteristics: good anti impact performance, small deformation temperature, good welding performance, anti fatigue performance, lamellar tearing resistance, micro alloying, high purity, and low carbon equivalent hydrogen sulfur resistant ability, products with good surface quality and dimensional tolerances.
Senior staff members with specific industry expertise cover a variety of corrosion problems that are encountered in industries such as oil and gas production, oil and gas transmission, energy conversion systems, and nuclear power systems. A wide variety of corrosion related tests can be undertaken at TCR Engineering Services in India to determine weight loss corrosion, intergranular corrosion attack, pitting corrosion, corrosion fatigue, stress corrosion cracking, sulfide stress corrosion cracking, and hydrogen-induced corrosion cracking.
