Notes:

• Hot-Rolled Plates: Typically priced lower due to simpler processing (e.g., $570–650/ton for 6–50 mm plates).
• Normalized Plates: Command a premium ($600–700/ton) due to enhanced toughness from heat treatment.
• Thicker Plates: Prices increase for plates above 50 mm due to higher material and processing costs.
• Customized Plates: Plates with additional testing (e.g., HIC for sour service) or clad options (e.g., with 304/316L) can exceed $800/ton.

These prices are indicative and based on sources from the China market as of January and September 2025. Actual prices may vary depending on order volume, supplier location (e.g., Nanjing, Rizhao), and global market trends. For precise 2025 pricing, contact Gangsteel directly for tailored quotes.

Factors Influencing ASTM A516 Gr 70 Boiler Plate Prices in China (2025)

The pricing of ASTM A516 GR 70 boiler plates in China’s competitive market is driven by several dynamic factors:

• Raw Material Costs: Fluctuations in iron ore, manganese, and carbon prices directly impact production costs. China’s robust steel industry closely tracks global commodity trends.
• Market Demand: High demand for ASTM A516 GR 70 in China’s oil and gas sector, particularly for LNG projects, drives price volatility.
• Production Processes: Normalized plates, requiring advanced heat treatment, command a premium over hot-rolled plates due to enhanced toughness.
• Supply Chain Dynamics: China’s export policies, port logistics, and domestic steel production capacity influence pricing. Tariffs and shipping costs also play a role.
• Customization and Testing: Plates with specific thicknesses, sizes, or additional certifications (e.g., HIC testing, ultrasonic inspection) increase costs due to specialized processing.
• Currency and Economic Factors: Exchange rate fluctuations and China’s economic policies affect export pricing for international buyers.

Gangsteel leverages its expertise and established supply chain in China to offer competitive pricing for ASME SA516 GR 70 plates, ensuring cost-effectiveness without compromising quality.

Chemical Composition

The chemical composition of ASTM A516 GR 70 ensures its suitability for pressure vessels, contributing to its value in the market. The table below outlines its composition per ASTM standards:

Key Notes:

• Carbon: Capped at 0.27% to ensure weldability, critical for boiler fabrication in China’s oil and gas industry.
• Manganese: The 0.85–1.20% range enhances strength and toughness, supporting high-pressure applications.
• Phosphorus and Sulfur: Low levels (0.035% max) improve notch toughness, vital for low-temperature performance in LNG storage.
• Aluminum: Ensures fully killed steel, reducing gas inclusions and enhancing quality, which adds value to the price.

Gangsteel’s ASTM A516 GR 70 plates meet both ASTM and ASME SA516 GR 70 standards, with rigorous testing to ensure compliance for China’s market.

Mechanical Properties

The mechanical properties of ASTM A516 GR 70 underpin its premium pricing in China, offering exceptional performance for boiler and pressure vessel applications. The table below summarizes its properties:

Highlights:

• Tensile Strength: The 485–620 MPa range ensures durability in high-pressure boilers, justifying its cost in China’s competitive market.
• Yield Strength: A minimum of 260 MPa supports structural integrity in demanding applications.
• Elongation: 17–21% ductility enables complex fabrication without compromising strength.
• Impact Toughness: Performance at -46°C supports cryogenic applications, such as LNG storage, adding value for China’s energy sector.

Compared to ASTM A516 GR 65 (450–585 MPa) and ASTM A516 GR 60 (415–550 MPa), ASTM A516 GR 70 offers superior strength, often commanding a higher price for robust applications.

Applications in China’s Oil and Gas Industry

ASTM A516 GR 70 is a cornerstone material in China’s oil and gas industry, where its properties drive demand and pricing:

• Boilers: Used in refineries and gas processing plants for steam generation, requiring high strength and thermal stability.
• Pressure Vessels: Essential for hydrocarbon storage and processing, including LNG and crude oil, under high-pressure conditions.
• Cryogenic Equipment: Ideal for LNG storage tanks due to its low-temperature toughness.
• Pipelines and Fittings: Employed in gas processing facilities, where reliability in cold environments is critical.

Gangsteel’s ASME SA516 GR 70 plates meet ASME standards, ensuring compliance for China’s high-demand oil and gas projects.

Weldability

ASTM A516 GR 70 is fully killed carbon steel, offering superior weldability with processes like SMAW, GTAW, and SAW. Its low carbon content minimizes weld imperfections, while normalization enhances toughness, adding value for fabrication in China’s industrial sector. Gangsteel supplies plates in normalized or hot-rolled conditions to meet specific project requirements.
