ASTM A240 SS304 STAINLESS STEEL PRECISION STRIP BA FOR SENSOR ELEMENT
ASTM A240 is a standard established by ASTM International (formerly American Society for Testing and Materials),Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and General Applications. It defines requirements for chemical composition, mechanical properties, and dimensional tolerances.The precision strip refers to steel strip produced by precision cold rolling, typically with very thin thickness (down to 0.05mm), narrow width, tight dimensional tolerances (as precise as ±0.005mm), high surface finish, and clean edges.
Key Parameters & Properties
- Chemical Composition (per ASTM A240 for SS304):
- Carbon (C): ≤0.07%
- Chromium (Cr): 17.5% – 19.5%
- Nickel (Ni): 8.0% – 10.5%
- Silicon (Si): ≤0.75%
- Manganese (Mn): ≤2.0%
- Common Dimensions:
- Thickness: 0.05mm – 3.0mm (precision strip typically thinner: 0.01mm – 1.5mm)
- Width: 2.0mm – 650mm (can be custom slit to width)
- Mechanical Properties:
- Tensile Strength: ≥515 MPa
- Yield Strength (0.2% offset): ≥205 MPa
- Hardness: Typically ≤92 HRB (Rockwell B) in solution-annealed condition
- Characteristics: 304 offers good corrosion resistance, excellent formability, and can be significantly strengthened and hardened by cold working (the process used to make precision strip). It is non-magnetic in the annealed condition but may become slightly magnetic after cold working.
Main Applications
Due to its high precision and clean surface, 304 precision strip is commonly used in:
- Electronics industry: Mobile phone components, computer hard drive parts, precision springs
- Medical devices: Surgical instruments, medical equipment components
- Automotive industry: Cylinder head gaskets, sensor elements, retaining rings
- Other high-end manufacturing: Heat exchangers, precision instruments, kitchenware, chemical equipment
