What are the common thicknesses for stainless steel strips?

At Ruixiang Steel, we offer thicknesses ranging from ultra-thin precision strips at 0.03mm up to 3.0mm, suitable for a wide range of industrial applications.

Which stainless steel strip is best for medical devices?

Grade 316L is typically recommended for medical applications due to its superior corrosion resistance and biocompatibility compared to Grade 304.

1. Understanding Stainless Steel Strip Grades

Choosing the right grade is the first step in optimizing cost and performance. At Ruixiang, we specialize in both Austenitic and Ferritic series:

Austenitic Series (300 Series)

Grade 304/304L: The "Workhorse" of the industry. Excellent corrosion resistance and drawability. Ideal for household appliances and kitchenware.
Grade 316L: Contains molybdenum, offering superior resistance to chlorides. Essential for medical grade stainless steel strips and marine hardware.

Ferritic Series (400 Series)

Grade 430: Known for its good corrosion resistance and magnetic properties. Widely used in automotive trim and cabinet panels.
Grade 410/420: Heat-treatable grades used for high-strength springs and cutting tools.

2. Technical Specifications: Precision is Our Standard

Unlike standard coils, precision stainless steel strips require ultra-tight tolerances. Our production capabilities include:

Feature	Specification Range
Thickness	0.03mm - 3.0mm
Width	3mm - 600mm (Precision Slitting)
Surface Finishes	2B, BA, No.4, Hairline, 8K Mirror
Hardness	ANN, 1/4H, 1/2H, 3/4H, FH (Full Hard)

3. Key Applications Across Industries

The versatility of our strips allows them to be used in diverse high-tech sectors:

Automotive: Cylinder head gaskets, exhaust system clamps, and trim components.
Electronics: EMI shielding, battery connectors, and precision springs.
Medical: Surgical instruments, orthodontic brackets, and capillary tubes.
Energy: Solar panel frames and heat exchanger fins.

4. Quality Control: The Ruixiang Advantage

As a leading stainless steel strip supplier, our commitment to quality is backed by advanced testing:
