SUS301 Stainless Steel Strip
Material Grade: SUS301 (AISI 301 equivalent)
Standard: JIS G 4309
Overview
SUS301 stainless steel strip is a high-strength austenitic stainless steel known for its excellent combination of corrosion resistance, formability, and elasticity. It is widely used in applications requiring durability, spring properties, and lightweight design.
Key Features
-
High Strength: Achieves superior tensile strength through cold working (1/4H, 1/2H, H, EH, and SEH tempers available).
-
Corrosion Resistance: Resists oxidation and atmospheric corrosion in mild environments.
-
Elasticity: Ideal for spring components and flexible applications.
-
Formability: Suitable for deep drawing, bending, and stamping processes.
-
Surface Finish Options: BA (Bright Annealed), 2B, No.4 (Brushed), or custom finishes.
Typical Applications
-
Spring washers, clips, and connectors
-
Electronic components (e.g., battery contacts, SIM card trays)
-
Automotive trim and fasteners
-
Medical instruments
-
Architectural decoration
