SUS201 vs SUS304 Stainless Steel Screws: Material Comparison and Application Solutions

How to Select the Right Stainless Steel Fasteners for Industrial Applications

Choosing the correct stainless steel screw material is critical for product reliability, corrosion resistance, and long-term performance.

Among stainless steel fasteners, SUS201 stainless steel screws and SUS304 stainless steel screws are two commonly used materials. Although both provide stainless steel characteristics, they have significant differences in chemical composition, mechanical properties, corrosion resistance, and application fields.

For engineers and purchasing teams, selecting the correct stainless steel fastener depends on:

• Operating environment

• Corrosion requirements

• Mechanical load

• Product appearance

• Cost considerations

As a professional stainless steel fasteners manufacturer, Juxin Fasteners provides stainless steel screws, bolts, and customized fastening solutions for automotive, electronics, medical equipment, industrial machinery, and OEM applications.

SUS201 Stainless Steel Screws: Cost-Effective Stainless Fastening Solution

Material Characteristics of SUS201 Stainless Steel

SUS201 stainless steel is a manganese-based stainless steel with:

• Higher manganese content

• Lower nickel content compared with SUS304

• Good basic corrosion resistance

• Competitive material cost

SUS201 stainless steel screws are suitable for applications where cost efficiency is important and environmental conditions are relatively moderate.

Advantages of SUS201 Stainless Steel Screws

Benefits include:

✔ Lower material cost
✔ Good strength performance
✔ Attractive stainless steel appearance
✔ Suitable for general industrial applications

However, compared with SUS304 stainless steel screws, SUS201 provides lower:

• Corrosion resistance

• Weather resistance

• Long-term durability

Applications of SUS201 Stainless Steel Screws

Common applications include:

Construction Industry

Used for:

• Indoor structures

• Decorative components

• General fastening applications

Furniture Manufacturing

Applications:

• Furniture assembly

• Hardware components

• Interior products

Electrical Appliances

Used for:

• Appliance housings

SUS201 is a practical choice when the application does not require maximum corrosion resistance.

SUS304 Stainless Steel Screws: Premium Corrosion-Resistant Fastening Solution

Material Characteristics of SUS304 Stainless Steel

SUS304 stainless steel is an austenitic stainless steel containing higher chromium and nickel content.

It provides:

• Excellent corrosion resistance

• Better tensile strength

• Superior durability

• Stable performance in demanding environments

SUS304 is one of the most widely used stainless steel materials for industrial fasteners.

Advantages of SUS304 Stainless Steel Screws

Benefits include:

✔ Excellent corrosion resistance
✔ High durability
✔ Good mechanical strength
✔ Clean and attractive appearance
✔ Suitable for harsh environments

SUS304 stainless steel screws are widely selected for applications requiring reliability and long service life.

2. Mechanical Performance Requirements

Applications with higher loads or vibration requirements should consider:

• SUS304 stainless steel screws

• Alloy steel fasteners

• High-strength stainless fasteners

3. Product Appearance Requirements

For visible components requiring a premium appearance:

SUS304 provides:

• Better surface finish

• Higher gloss

• Better long-term appearance
