Yes, SUS304 Is Classified As A Food-Grade Stainless Steel under international standards, including:
JIS G4305 (Japan)
ASTM A240 / A276 (USA)
EN 10088-1 (1.4301) (EU)
It contains:18% Chromium – for corrosion and oxidation resistance,8–10.5% Nickel – for toughness and formability,≤ 0.08% Carbon – for weldability and low reactivity,It Does Not Leach Harmful Substances under standard food-contact conditions, making it ideal for both acidic and alkaline environments.
Yes. 304 Stainless Steel (SUS304) is approved for Potable Water Systems by most global standards, including:NSF/ANSI 61 (US),WRAS (UK),EU Food Contact Regulation (EC 1935/2004),GB4806.9-2016 (China food safety standard for metal materials)
Its Non-Reactive Nature ensures No Metallic Taste, Rust, Or Harmful Contamination in drinking water distribution, bottling, or purification systems.
Both 304 and 316 stainless steels meet food-grade safety standards (such as FDA and EU EC 1935/2004 certification), but their application scenarios have different focuses due to differences in corrosion resistance.
304 (18Cr-8Ni) is a common choice for the food industry due to its excellent comprehensive corrosion resistance and cost-effectiveness. It is suitable for conventional scenarios such as beverage filling equipment, baking molds, and kitchen utensils, and can resist corrosion from organic acids, ethanol, and neutral food media.
316 (16Cr-10Ni-2Mo) has stronger resistance to chloride ion corrosion and high-temperature oxidation due to the addition of molybdenum. It is especially suitable for processing high-salt foods (such as pickled meats and seafood), dairy products (containing chloride ion cleaning fluids), and food processing equipment that comes into contact with seawater. It performs more stably in harsh environments such as soy sauce brewing and salted food storage.
We offer 304 in standard product forms including tubes, pipes, plates, strips, sheets, round bars, flat bars, forgings, hexagonal bars and wires. These products are available in a wide variety of sizes. For detailed specifications and product information, please visit the following website.
