304 Stainless Steel Coil 2B Finish For Food Processing Industry

304 Stainless Steel Coil 2B Finish for Food Processing Industry contains 18% chromium and 8% nickel, ensuring material safety and compliance from the source. This eliminates food safety hazards associated with inferior stainless steel, making it a preferred base material for food contact equipment manufacturing. The surface undergoes a 2B cold-rolled matte finish, resulting in a smooth, burr-free, and scratch-free surface with a non-reflective matte texture. This not only provides a clean visual appearance but also prevents food residue and bacteria from remaining on the surface, meeting the stringent hygiene requirements of the food processing industry.

Dairy Processing Equipment: Milk storage tanks, yogurt fermentation tanks, milk conveying pipelines, contact parts of dairy product filling equipment, etc. Resistant to the acidic environment of milk, preventing the release of harmful substances, ensuring the purity of dairy products, and avoiding milk contamination. Suitable for large dairy plants and small dairy processing workshops.

Baking and Pastry Equipment: Bread oven liners, cake molds, pastry processing equipment countertops and contact parts, etc. High temperature resistant, not easily deformed, easy to clean, preventing food from sticking during baking, and resistant to oxidation and corrosion under high temperature environments.

Other Food Processing Equipment: Fruit and vegetable washing machine liners, contact parts of meat processing equipment (meat grinders, slicers), food turnover boxes, food storage tanks, seasoning equipment rollers, etc. Suitable for various food processing scenarios such as puffed foods, fried foods, and pet food, meeting the customized needs of different equipment.

Material Composition Testing: Rapid screening using X-ray fluorescence spectroscopy (XRF) and precise determination using inductively coupled plasma optical emission spectroscopy (ICP-OES) confirm that the composition of the 304 stainless steel meets standards. The chromium (Cr) content is 18.0-20.0%, nickel (Ni) content is 8.0-10.5%, carbon (C) ≤0.08%, manganese (Mn) ≤2.0%, phosphorus (P) ≤0.045%, and sulfur (S) ≤0.03%. There are no harmful impurities, meeting the requirements of the 304 stainless steel standard, thus preventing material adulteration and the use of inferior materials.

Appearance and Performance Inspection: The 2B surface is inspected for flatness and smoothness, ensuring no burrs, scratches, or oxide scale, with a surface roughness Ra value ≤ 0.8μm for easy cleaning. Thickness and width errors are also inspected to ensure compliance with customization requirements. Salt spray and intergranular corrosion tests are conducted to verify the product's corrosion resistance, ensuring it is not prone to rust or corrosion in food processing environments. Processing performance is also tested to ensure no abnormalities occur during cutting, stamping, and bending, guaranteeing product stability and durability.

Certifications and Qualifications: The product possesses relevant certifications for food-grade stainless steel and can provide authoritative third-party testing reports (CMA accreditation), material certificates, and factory inspection reports. On-site inspections of the production process and testing procedures are available, ensuring full traceability and giving customers greater peace of mind during procurement. This helps customers successfully pass food industry compliance audits and market supervision inspections.

Q1: As a food-grade stainless steel coil, what precautions should be taken when using this product?

① Do not use strong corrosive cleaning agents (such as baking soda, bleach, sodium hypochlorite) to clean the surface, as this may damage the oxide film, leading to material corrosion and the release of harmful substances.

② Avoid storing highly acidic, alkaline, or salty foods (such as vinegar, soy sauce, pickles, and fruit juice) for extended periods, as this may accelerate metal release and affect food safety.

③ Do not dry-heat stainless steel, as this may release chromium and nickel compounds, damaging material properties and food safety.

④ Do not use steel wool or hard objects to scrub the surface, as this may scratch the surface, damage the oxide film, and lead to bacterial growth and material corrosion.

⑤ If rust spots, scratches, or black debris appear on the surface, replace the stainless steel immediately to avoid affecting food contact safety.

⑥ Avoid contact with non-food grade metals during processing to prevent cross-contamination, ensure food production safety, and comply with food processing hygiene standards.
