JIS G4304 SUS301 Stainless Steel Plate Stock

Gangsteel’s stainless steel stock features a wide selection of SUS301 stainless steel plates compliant with JIS G4304. This high-strength austenitic grade is renowned for its exceptional work-hardening capability, allowing it to achieve significantly higher tensile strength through cold rolling compared to standard SUS304.

In our stainless steel stock, SUS301 plates are offered in different tempers and thicknesses to suit various strength requirements. With higher carbon and lower nickel than some 300 series grades, SUS301 delivers outstanding spring properties and fatigue resistance, making it a top choice for demanding mechanical applications.

Key Advantages of SUS301

One of the biggest benefits of sourcing from our stainless steel stock is the ability to select plates with precise cold-worked properties. SUS301 can reach tensile strengths over 1000 MPa in harder tempers while retaining good ductility in the annealed state. This versatility makes it ideal when you need both formability during fabrication and high final strength in the finished part.

Wide Range of Applications

Customers rely on Gangsteel stainless steel stock for SUS301 plates in automotive components, springs, clips, electronic enclosures, elevator parts, and structural reinforcements. In the rail and transportation sectors, SUS301 provides lightweight yet strong solutions. It is also commonly used in medical devices and precision machinery where high elasticity is required.

Comparison with Similar Grades

Compared to SUS304, SUS301 offers much higher work-hardening rates, allowing thinner material to be used for the same strength level, which can reduce overall weight and cost. However, its corrosion resistance is slightly lower, so it performs best in mild environments or when properly protected.

Fabrication and Processing Guidance

Plates from our stainless steel stock can be readily formed, stamped, and welded. For spring applications, proper heat treatment or cold rolling to the desired temper is essential. Gangsteel provides technical support on forming parameters to help you maximize yield and minimize defects.
