Hemaokang Steel (Shandong) Co., Ltd. takes pride in offering premium 430 Stainless Steel Coil 2B Surface 0.8mm Thickness Cold Rolled, manufactured in strict compliance with JIS G4305 standard. With an annual export value ranging from US$50 million to US$100 million and ISO9001 certification, we ensure each coil delivers consistent quality, tight tolerances, and excellent surface finish. Our cold-rolled 430 stainless steel coils are specifically engineered for applications requiring corrosion resistance, formability, and cost efficiency—making them a reliable choice for global buyers in North America, Europe, Southeast Asia, and beyond.
This product combines the strength of ferritic stainless steel with the smooth, reflective 2B surface achieved through cold rolling and annealing. The 0.8mm thickness offers optimal balance between rigidity and flexibility, supporting diverse fabrication processes such as stamping, bending, and welding. Below we detail the technical specifications, advantages, and why Hemaokang Steel stands out as your trusted partner.

Product Advantages & Customer Benefits
- Excellent Formability: The 0.8mm thickness combined with a fully annealed ferritic structure allows deep drawing and bending without cracking, ideal for kitchen sink rims, oven panels, and automotive trim.
- Consistent Surface Quality: The 2B finish provides a uniform matte appearance that accepts painting or further polishing, reducing post-processing time for end users.
- Cost-Effective Alternative to 304: 430 stainless steel offers good corrosion resistance at a lower material cost, making it popular for indoor applications where aesthetic and durability are important.
- Magnetic Property: Unlike austenitic grades, 430 is magnetic, which can be an advantage in certain fastening or assembly applications.
- Easy to Weld: With proper filler and procedures, 430 coils can be welded for structural components subject to non-severe environments.
- Customizable Dimensions: We offer slit widths and coil weights to match your exact production requirements, minimizing waste.
The 430 stainless steel coil is widely used in kitchenware (cooking utensils, sinks), household appliances (microwave oven liners, dishwasher interiors), automotive trim, heat exchangers, and architectural decoration. Its combination of utility and affordability makes it a staple in many industrial supply chains.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 430 and 304 stainless steel?
A: 430 is ferritic (magnetic) with lower corrosion resistance than austenitic 304, but it is more cost-effective and offers good performance in indoor environments. 304 is preferred for high-corrosion or outdoor applications. -
Q: Can the 2B surface be polished to a mirror finish?
A: Yes, the 2B surface is a good base for subsequent polishing, brushing, or coating. Many customers use it as-is for its uniform matte look or further process it to achieve a #4 or #8 finish. -
Q: What is the typical lead time for bulk orders?
A: For standard specifications (0.8mm thickness, common widths), we can ship within 15–20 days after order confirmation. Custom widths may require 25–30 days. -
Q: Do you provide samples before bulk order?
A: Absolutely. We offer free samples (freight collect) for evaluation. Please contact our sales team to request a sample. -
Q: Is this coil suitable for food contact?
A: 430 stainless steel is commonly used for kitchen tools and some food processing equipment. However, for direct food contact under acidic or high-temperature conditions, please confirm with local regulations; we can provide material test certificates. -
Q: What certifications do you have?
A: Our factory is ISO9001 certified. We can also provide mill test certificates (MTC) per JIS G4305 requirements. Other certifications can be arranged upon request. -
Q: How is the coil packaged to prevent damage during shipping?
A: Each coil is wrapped with water-proof paper, plastic film, and steel strapping, then protected with wooden frames or crates for sea freight. Custom packaging is available. -
Q: Can you supply other thicknesses besides 0.8mm?
A: Yes, we produce cold-rolled 430 coils from 0.3mm to 3.0mm. Please specify your desired thickness when inquiring.
