Q: What are the core standards for SPCC? A: JIS G3141 (Japan), GB/T 11253 (China), EN 10130 (EU, corresponding to DC01).
Q: What are the factory inspection items for SPCC? A: Chemical composition, hardness, surface quality, dimensional tolerances, flatness; SPCCT plus tensile and elongation tests.
Q: What are the thickness tolerances for SPCC (JIS G3141)? A: ≤1.0mm: ±0.05mm; 1.0–2.0mm: ±0.07mm; 2.0–3.2mm: ±0.10mm; tolerances can be tightened as needed.
Q: How to determine if SPCC conforms to JIS standards? A: Check the standard number, composition, hardness, and surface/tempering/conditioning markings on the quality certificate; third-party testing (such as SGS) may be necessary.
Q: What parameters should the SPCCT report for SPCC include? A: Yield strength (σs), tensile strength (σb), elongation (δ5), hardness (HRB/HV), and specify the test standard (e.g., JIS Z2241).
