The core is whether the plate can consistently form under the intended process, maintain dimensional accuracy, and retain properties post-processing. Assessment combines measurable indicators and practical validation:
Machining performance: smooth cutting, low tool wear, easily broken chips without entanglement; finished surface roughness should meet standards (e.g., Ra ≤1.6 μm), free of burrs or edge chipping, and dimensions easily controlled.
Welding performance: no cracks, porosity, or slag inclusions; weld strength not lower than the base material; minimal distortion during welding; stable performance without complex preheating or post-weld treatment.
Cold forming performance: bending, stamping, or stretching without cracking, delamination, or excessive springback; high shape accuracy post-processing.
Hot processing adaptability: if high-temperature steps are required, material must withstand temperature without oxidation, excessive grain growth, or significant performance loss.
Post-processing property retention: core properties (strength, corrosion resistance) remain intact; e.g., machined surfaces are not prone to corrosion, welds maintain corrosion resistance.
