ASTM A515 gr.70 carbon-silicon steel plates

ASTM A515 plate, also know as ASME SA515 plate, covers carbon-silicon plate for higher-temperature service.

ASTM A515 Grade 70 plates are carbon steel primarily for service in Intermediate and Higher Temperature pressure vessels. A515 Grade 70 carbon steel plates are widely used in the fabrication of boilers in industries such as shipbuilding,petrochemical and manufacturing.

A515 70 is a carbon steel plate specified under the ASTM A515 standard for pressure vessel plates, designed for intermediate and higher-temperature service. These plates are normalized to enhance their mechanical properties, making them ideal for applications such as boilers, heat exchangers, and other pressure vessels operating under elevated temperatures. Gangsteel ensures that our ASTM A515GR70 steel plates meet stringent quality standards, offering thicknesses from 6mm to 300mm, widths from 1500mm to 4050mm, and lengths from 3000mm to 15000mm.

ASTM A515 GR.70 is widely used in industries requiring robust materials for high-temperature and high-pressure environments. Common applications include:

• Boilers and Pressure Vessels: Ideal for fabricating boilers and pressure vessels due to its high tensile strength and heat resistance.
• Heat Exchangers: Used in heat exchangers for efficient heat transfer under elevated temperatures.
• Power Generation: Employed in power plants for components exposed to high temperatures.
• Petrochemical Industry: Suitable for storage tanks and processing equipment in petrochemical plants.

GNEESTEEL's ASTM A515GR.70 steel plates are tested for supplementary requirements such as HIC (Hydrogen Induced Cracking) and NACE MR0175, ensuring reliability in harsh environments.

To help you choose the right material, we compare A515 70 with other grades in the ASTM A515 family:

ASTM A515 Grade 60: Offers lower strength but higher ductility, suitable for less demanding applications.

ASTM A515 Grade 65: A middle ground with balanced strength and ductility, ideal for moderate-temperature services.

ASTM A515GR70: Provides the highest strength, making it perfect for high-pressure and high-temperature environments.

For a broader perspective, we compare ASTM A515 GR.70 with ASTM A516 grades, which are designed for moderate and lower-temperature services:

ASTM A516 Grade 55: Best for low-temperature applications with high ductility.

ASTM A516 Grade 60: Similar to A515 Grade 60 but optimized for lower temperatures.

ASTM A516 Grade 65: Offers a balance of strength and toughness for moderate conditions.

ASTM A516 Grade 70: Matches A515 70 in strength but is designed for lower-temperature service.

For high-temperature applications, ASTM A515GR70 outperforms A516 grades due to its normalized structure and enhanced heat resistance.

ASTM A515 GR.70 has equivalent grades in various international standards, ensuring compatibility for global projects:

These equivalents allow flexibility in sourcing materials while maintaining performance standards.
