Feature	Grade 304	Grade 316	Grade 430
Chromium (%)	18-20	16-18	16-18
Nickel (%)	8-10.5	10-14	<1
Molybdenum (%)	<1	2-3	<1
Corrosion Resistance	Excellent	Superior	Good
Strength	High	High	Moderate
Weldability	Excellent	Excellent	Good
Formability	Excellent	Excellent	Good
Cost	Moderate	High	Low

Different Types of 4mm Stainless Steel Sheet

The variety of 4mm stainless steel sheets available is vast, primarily due to the differing grades of stainless steel used. Each grade possesses unique characteristics that suit specific applications. Suppliers such as SH Stainless (www.shstainless.com) offer a broad selection of grades and thicknesses. Here’s a comparison of some common types:

Grade	Type of Stainless Steel	Primary Applications	Key Characteristics
304	Austenitic	Food processing, architectural cladding, kitchenware	Excellent corrosion resistance, high formability, weldability
316	Austenitic	Marine environments, chemical processing, medical devices	Superior corrosion resistance, especially to chlorides
430	Ferritic	Automotive exhaust systems, appliances	Good corrosion resistance, high strength, cost-effective
201	Austenitic	General purpose applications where cost is a factor	Lower cost than 304, slightly lower corrosion resistance
202	Austenitic	Similar to 201	Lower cost than 304, slightly lower corrosion resistance

Surface Treatments

Various surface treatments further enhance the versatility of 4mm stainless steel sheet. These treatments affect the sheet’s appearance and properties. JingZhan Metal Technology (www.jingzhansteelfactory.com) highlights the importance of surface treatment in their product descriptions. Common finishes include 2B (mill finish), No. 4 (brushed), BA (bright annealed), and 8K (mirror finish). The choice of finish depends on the aesthetic and functional requirements of the application.

Manufacturing Processes

The manufacturing process significantly impacts the final properties of the sheet. Hot-rolled and cold-rolled processes are the most common. Hot-rolled sheets are generally thicker and possess superior strength, while cold-rolled sheets offer better surface finish and dimensional accuracy. Star Good Steel Group (stargoodsteelgroup.com) details the differences between hot-rolled and cold-rolled stainless steel in their product descriptions.

Conclusion

4mm stainless steel sheet from Chinese manufacturers presents a diverse range of options catering to various industrial and consumer needs. Understanding the technical specifications, grade differences, and surface treatments is key to selecting the appropriate sheet for any given application. Careful consideration of these factors ensures the optimal performance and longevity of your project.
