ASTM A515 Gr 70 Plates and SA 515 Grade 70 boiler steel plates

A: A515 Grade 70 is a type of carbon steel plate specified by ASTM and ASME standards for use in intermediate and higher temperature applications, such as boilers and pressure vessels. It has a high tensile strength range of 70-90 ksi (485-620 MPa) and a minimum yield strength of 38 ksi (260 MPa). This grade is often normalized to improve its mechanical properties. 

A: Equivalent material of ASTM A515 Grade 70 steel plate have JIS G3103 SB480, DIN 1715 1.0844, A48 CP,AP,FP; Fe 460-2-KW, SS21,02,01; Gr 360,400; ASTM A414 Grade F.

A: Chemical Composition: ASTM A515 plates typically consist of carbon, manganese, phosphorus, sulfur, and silicon, with specific limits on these elements to achieve desired mechanical properties.

A: ASTM A515GR70 is designed for intermediate and higher-temperature service, while ASTM A516 Grade 70 is optimized for moderate and lower-temperature applications. A515 Grade 70 has a normalized structure for enhanced heat resistance, whereas A516 Grade 70 offers better toughness in colder environments.

A: SA-516-70 is a carbon steel plate specification for moderate and lower temperature service. SA515 GR 70 is a carbon-silicon steel plate for intermediate or higher temperature service. Maximum thickness: SA-516-70 has a maximum thickness of 204 mm, while SA515-GR-70 has a maximum thickness of 50 mm.

A: A515 70 is commonly used in boilers, pressure vessels, heat exchangers, and petrochemical equipment due to its high strength and ability to withstand elevated temperatures.

A: Yes, ASTM A515 GR.70 has excellent weldability, thanks to its controlled carbon equivalent (Ceq). Proper welding procedures should be followed to maintain its properties.

A: Gangsteel offers ASTM A515GR70 plates in thicknesses from 6mm to 300mm, widths from 1500mm to 4050mm, and lengths from 3000mm to 15000mm, customizable to project requirements.

A: Yes, Gangsteel's ASTM A515GR.70 plates are tested for NACE MR0175 and HIC, ensuring suitability for sour service environments.
