Calculated as I = 26.01Cu + 3.88P + 1.20Cr + 1.49Ni, exceeding industry standards for long-term durability in marine and industrial environments . |
High strength plate has excellent load-bearing capacity and can maintain good toughness even at low temperatures, which can meet the needs of various high-strength structures; high strength steel plate also has certain corrosion resistance, good welding performance and processing performance, which is convenient for construction and manufacturing, and is widely used in many fields.
Energy and power generation:
Boiler plates, turbine components, and steam headers made from heat-resistant alloys.
Oil and gas:
Storage tanks, pressure vessels, and wellhead components using a516 grade 70 or similar grades.
Mining and earthmoving equipment:
Chutes, dump truck liners, and excavator parts fabricated from abrasion-resistant plates.
Shipbuilding and offshore structures:
Marine-grade alloy plates resist corrosion and fatigue in harsh marine conditions.
Heavy machinery and construction:
Alloy plates are used for lifting arms, boom structures, and gear bases in cranes and bulldozers.
Manufacturing Process of GB Alloy Steel Plate
Refined smelting:
Lf furnace desulfurization ensures s ≤0.015%, minimizing impurities.
Precision rolling:
Final rolling at 820–860°c, followed by accelerated cooling to ≤550°c, optimizes grain structure for high strength and toughness.
Surface optimization:
Optional shot blasting, pickling, or chemical oxidation treatments enhance coating adhesion for specialized applications.
