Premium SA387Gr.21 Steel Plate for Boilers & Pressure Vessels

High-Temperature Performance
– Superior SA387Gr.21 alloy steel ensures exceptional strength and corrosion resistance under extreme heat (up to 600°C), ideal for boilers, reactors, and high-pressure systems.
Precision Manufacturing
– Uniform thickness (medium to heavy gauge) with mill-certified composition (C, Cr, Mo balanced) for consistent weldability, durability, and stress resistance in critical industrial applications.
Cost-Efficient Bulk Supply
– Direct factory sourcing guarantees the lowest global pricing without compromising ASTM/ASME compliance. Stocked in multiple sizes for fast large-volume orders.
Versatile Industrial Use
– Trusted in power plants, petrochemical refineries, and pressure vessel fabrication due to its creep resistance and crack-proof microstructure.
Quality Assurance
– Fully tested for hardness, impact toughness, and dimensional accuracy—backed by full traceability documentation.
Global Logistics Ready
– Optimized packaging for secure shipping; wholesale discounts available for container-load purchases.
