Factory Direct Food Safe Stainless Steel Coils SUS631/177PH/S31803/F52 for Food Packaging and Can Making

Product Overview

Our factory-direct food-safe stainless steel coils, including SUS631, 17 - 7PH, S31803, and F52, are the ideal choice for food packaging and can - making applications. These stainless steel coils are crafted with precision and adhere to the highest quality standards, ensuring safety and durability in food - related industries.

Surface Treatment

The surface of these stainless steel coils undergoes a polished treatment. This polished finish not only gives the coils an aesthetically pleasing appearance but also offers several practical benefits. It makes the surface smooth, which is crucial for food packaging as it reduces the risk of food particles adhering to the surface. Moreover, a polished surface is easier to clean, maintaining high levels of hygiene. The smooth finish also enhances the corrosion resistance of the stainless steel, protecting the coils from the harsh environments often associated with food processing and storage.

Manufacturing Technique

These coils are produced using the hot - rolled technique. Hot rolling is a well - established manufacturing process that involves heating the steel above its recrystallization temperature and then passing it through rollers. This process results in a more uniform grain structure within the steel, improving its mechanical properties. The hot - rolled coils have better ductility and toughness, making them suitable for forming operations required in food packaging and can - making. They can be easily shaped into various forms without cracking or breaking, ensuring high - quality end products.

Standards Compliance

Our stainless steel coils strictly follow the ASTM (American Society for Testing and Materials) standards. ASTM standards are globally recognized for their rigor and comprehensiveness in ensuring the quality and performance of materials. By adhering to ASTM standards, our coils guarantee consistent quality, dimensional accuracy, and mechanical properties. This compliance also means that our products can be used in international markets with confidence, as they meet the requirements of many regulatory bodies around the world.

Types of Stainless Steel

1. SUS631: This is a precipitation - hardening stainless steel. It offers a good combination of high strength and corrosion resistance. In food packaging, its strength allows for the creation of thin - walled containers without sacrificing durability. Its corrosion resistance ensures that it can withstand the acidic and alkaline substances commonly found in food products.
2. 17 - 7PH: Similar to SUS631, 17 - 7PH is a precipitation - hardening stainless steel. It has excellent strength and can be heat - treated to achieve different levels of hardness. This makes it versatile for various food packaging applications, from lightweight containers to more heavy - duty can - making.
3. S31803 (Duplex Stainless Steel): S31803 combines the advantages of austenitic and ferritic stainless steels. It has high strength, good corrosion resistance, and excellent resistance to stress - corrosion cracking. In the food industry, where products may be exposed to different types of corrosive substances, S31803 provides long - lasting protection for food packaging and cans.
4. F52: F52 is a high - performance stainless steel with enhanced mechanical properties. It offers superior strength and toughness, making it suitable for applications where the packaging or cans may be subjected to high pressure or impact during handling and transportation.
