Q: Can Q235 cold-rolled steel sheet be used in the core load-bearing parts of car seats?
A: No. Core load-bearing parts such as seat rails and main frames require high-strength cold-rolled or hot-rolled steel sheets. Q235 is only used in non-load-bearing parts such as seat side panels and headrest bracket components.
Q: Is Q235 cold-rolled steel sheet used in automotive exhaust systems?
A: Almost never. Exhaust systems are hot and corrosive. Q235 has poor high-temperature and corrosion resistance. Stainless steel or galvanized steel sheet is more commonly used in these parts.
Q: What are the uses of Q235 cold-rolled steel sheet in automotive headlight components?
A: Non-optical, non-sealed core components such as the metal backplate of the headlight housing, headlight mounting brackets, and lamp holder fixing bases.
Q: Is Q235 cold-rolled steel sheet used in automotive fuel tank components?
A: Q235 cold-rolled steel is only used for external mounting brackets and protective covers of the fuel tank. Due to sealing, oil resistance, and impact resistance requirements, the fuel tank body itself will not use Q235 cold-rolled steel.
Q: Is there a difference between the application of Q235 cold-rolled steel in new energy vehicles and traditional fuel vehicles?
A: Basically the same. New energy vehicles only increase the use of Q235 steel in non-core components such as external battery pack protective plates, wiring harness brackets, and charging pile connection brackets. The battery pack body and core vehicle structure still require specialized high-strength steel; Q235 is not used in the manufacture of core components.
