Q: What are the core advantages of SPCC?
A: Smooth surface, high dimensional accuracy; good formability (stamping/bending/stretching); excellent weldability; low cost.
Q: What are the main limitations of SPCC?
A: Poor corrosion resistance, prone to oxidation and rust; relatively low strength, unsuitable for heavy-duty structural components; outdoor protection is required without coating.
Q: How is the weldability of SPCC?
A: Its low carbon content makes it highly weldable, suitable for spot welding, MIG/MAG, TIG, and arc welding; no preheating required before welding, and minimal deformation after welding.
Q: What is the machinability of SPCC?
A: Machinability is average; low-speed cutting is prone to tool sticking; it is recommended to use YG-type carbide tools, add cutting fluid, and appropriately increase the cutting speed and feed rate.
Q: What are the coating and electroplating compatibility of SPCC?
A: Smooth and clean surface, suitable for spraying, electrophoresis, and electroplating; pretreatment requires degreasing, derusting, and phosphating to improve adhesion.
