A Comprehensive Guide to Stainless Steel Sheets in China

China is a leading global producer and exporter of stainless steel sheets, catering to diverse industrial and consumer needs. Understanding the various types, grades, and technical specifications is crucial for selecting the right material for specific applications. This guide provides an in-depth exploration of stainless steel sheets available from Chinese suppliers like sanmeimetal.com, www.stainlesssteelmetalsheet.com, www.civmats.com, www.aoxingmetal.com, and www.stainlesssteel-sheetmetal.com.

Understanding Stainless Steel Grades

Stainless steel sheets are categorized into different grades based on their chemical composition and resulting properties. The most common grades include austenitic (304, 316, 310S), ferritic (430, 439), martensitic (410, 420), and duplex stainless steels. Each grade offers a unique balance of corrosion resistance, strength, and workability. For example, 304 stainless steel, widely used by sanmeimetal.com, is known for its excellent corrosion resistance and formability.

The choice of grade depends heavily on the intended application. www.stainlesssteelmetalsheet.com highlights the popularity of 304 and 316 grades for various applications. High-temperature applications might necessitate the use of grades like 310S, while applications requiring superior corrosion resistance might opt for 316L. CIVMATS, a leading exporter, stocks a wide range of grades to meet diverse demands.

Technical Features of Common Grades

The following table compares the technical features of some commonly used stainless steel sheet grades:

Grade	Tensile Strength (MPa)	Yield Strength (MPa)	Elongation (%)	Corrosion Resistance	Heat Resistance	Formability
304	515-690	205-275	40-50	Excellent	Good	Excellent
304L	485-655	170-240	40-50	Excellent	Good	Excellent
316	515-690	205-275	40-50	Excellent	Good	Good
316L	485-655	170-240	40-50	Excellent	Good	Good
430	275-415	170-275	20-30	Good	Fair	Good
410	485-690	275-415	15-25	Moderate	Good	Moderate

These values are approximate and can vary based on the specific manufacturer and processing techniques. Aoxingmetal.com, for instance, provides detailed specifications for each grade they offer.

Types of Stainless Steel Sheets and Their Differences

Stainless steel sheets are available in various forms, distinguished by their surface finish, thickness, and dimensions. The most common types include:

Type	Surface Finish Examples	Thickness Range (mm)	Applications
Cold Rolled Sheet	2B, No.1, No.4, BA, Hairline	0.3 – 3.0	Wide range of applications, including decorative uses
Hot Rolled Sheet	Usually not highly polished	1.0 – 10.0	Structural applications, where high precision isn’t crucial
Perforated Sheet	Various	Varies	Filtration, decorative screens
Mirror Polished Sheet	Mirror finish	Varies	Decorative, architectural applications

These are just some examples. Jiangsu Mittel Steel Industrial Limited, featured on www.stainlesssteel-sheetmetal.com, offers a wide variety of surface finishes and thicknesses. Sanmei Metal also provides customized lengths and widths to meet specific project requirements. CIVMATS provides options with or without PVC film protection.
