ASTM A515 Grade 70 Steel Plate
Products Description
ASTM A515 Gr 70 Plates has excellent features such as wear resistant, high strength, sturdy construction, corrosion-resistant, rugged design, and optimum quality. The surface finishes in which these plates can be received are checkered, brush, sandblasting and embossed, 2B, BA, 8K, No 1, etc. It is popularly available in hot rolled finish.
ASTM a 515 gr 70 CS Plate is also called as ASME SA516 Gr 70 CS Plate. It is a medium carbon alloy that also contains amounts of manganese, phosphorus, sulfur, and silicon. It is primarily used for service in welded pressure vessels where improved notch toughness is required.
A515 gr.70 HR Boiler Plates are relatively thick, high-quality sheet steel used in the construction of a boiler. It is produce to make a superior quality carbon steel plate which have consistent controlled properties and are invented to resist the internal pressure of pressure vessels, boilers and valves

Performance Advantages
High Strength and Excellent Mechanical Properties
It boasts outstanding tensile strength (485-620 MPa) and yield strength (≥260 MPa), enabling it to stably withstand high-pressure loads and meet the stringent structural strength requirements of equipment such as pressure vessels and boilers.
Adaptable to Medium and High-Temperature Environments with Remarkable Stability
Designed specifically for medium and high-temperature scenarios, it can maintain structural stability and mechanical properties even in environments above 350°C. It is particularly suitable for equipment that operates in medium and high temperatures for long periods, such as boilers and steam generators, preventing performance degradation caused by temperature fluctuations.
Excellent Weldability and Processing Adaptability
It is compatible with conventional welding processes such as arc welding and submerged arc welding. When used with low-hydrogen electrodes (e.g., E7018), it can achieve high-quality welds, reducing welding difficulty and process costs.
It supports various processing methods including laser cutting, flame cutting, and stamping forming. Thick plates can effectively avoid cracks after preheating treatment, adapting to the manufacturing needs of complex components.
Strict Quality Control Ensures Reliability
It must pass 100% ultrasonic flaw detection (in accordance with ASME SA20/SA20M standards) before leaving the factory to ensure no internal defects. This avoids potential safety hazards caused by material flaws from the source and meets the quality compliance requirements of high-risk equipment such as pressure vessels.
