Products Description
I. Key Points for Food Contact Material Certification
For use in food machinery, materials must comply with EC Regulation 1935/2004. Critical Control Points include:
1. Surface coatings must be certified according to FDA 21CFR175.300.
2. Welded areas must be passivated.
3. Contact surface roughness must be controlled to Ra ≤ 0.4μm.
4. Regular testing for heavy metal migration (lead < 0.01mg/kg).
II. Core Performance Parameters and Testing Standards
According to EN 10130, typical mechanical properties of this material include: yield strength of 140-280 MPa, tensile strength of 270-410 MPa, and elongation ≥ 28%. Rockwell hardness values range from 40-75 HRB, with excellent deep-drawability (r-value ≥ 1.8). Electrochemical testing shows that after passivation, its salt spray corrosion resistance can reach over 120 hours.
III. Material Composition and Production Process Characteristics
DC01 is a low-carbon cold-rolled steel sheet, primarily composed of an iron matrix with trace amounts of carbon and manganese. Produced using a continuous cold rolling mill, key processes include pickling and descaling the hot-rolled coil, multiple cold-rolling passes, protective atmosphere annealing, and leveling. This process combination ensures a product tolerance of 0.8-1.2mm and a surface roughness of Ra ≤ 0.8μm.
IV. Typical Application Scenarios
1. Automotive Industry: Door inner panels, fuel tank brackets, and other structural components.
2. Home Appliance Manufacturing: Washing machine drums, microwave oven chambers.
3. Food Equipment: Retort liner, conveyor belt support frames.
4. Architectural Decoration: Elevator car panels, metal ceilings.
By optimizing heat treatment parameters, DC01 steel plate can be further upgraded to ultra-deep-drawing grade DC04 to meet more complex forming requirements.
