304 Stainless Steel Sheet

Q1: What are the common thickness and size specifications of 304 stainless steel sheets?

A1: Common thickness ranges from 0.3mm to 10mm. Standard sizes are 1000mm×2000mm, 1220mm×2440mm, and 1500mm×3000mm. For special applications, customized sizes (width and length) can be provided. Thin sheets (≤1.0mm) are often used for decorative parts and small components, while thick sheets (>3.0mm) are suitable for structural parts and equipment casings.

Q2: What processing methods are 304 stainless steel sheets suitable for?

A2: 304 stainless steel sheets have good processability and can undergo various processing methods, including cutting (shearing, laser cutting, plasma cutting), bending, stamping, welding, and polishing. Laser cutting is suitable for precision cutting of complex shapes; stamping is used to produce various formed parts (such as sinks, decorative panels); welding can realize the assembly of large components.

Q3: Why do 304 stainless steel sheets sometimes have surface defects, and how to avoid them?

A3: Common surface defects include scratches, pits, and stains. The main causes are raw material quality problems, improper processing, and poor storage. To avoid them: 1. Choose high-quality raw materials from regular manufacturers. 2. Use professional processing equipment with smooth tool surfaces; avoid collision during processing. 3. Store in a dry, clean warehouse, separate from sharp objects and corrosive substances; cover with waterproof cloth.

Q4: What are the differences between 304 stainless steel sheet and 316 stainless steel sheet in application?

A4: 304 stainless steel sheet is suitable for general corrosion environments (atmosphere, fresh water, mild chemicals) and is widely used in architectural decoration, kitchenware, and general equipment. 316 stainless steel sheet contains molybdenum, which has better corrosion resistance to chloride ions, so it is used in marine environments, chemical industry (strong corrosive fluids), and medical equipment with higher requirements. 304 is more cost-effective than 316.

Q5: How to choose the right surface finish for 304 stainless steel sheets?

A5: Choose based on application scenarios: 1. 2B finish (matte): Suitable for equipment casings, kitchenware, and parts that require subsequent polishing. 2. BA finish (bright): Used for decorative parts (such as elevator panels, decorative walls) that require a mirror-like appearance. 3. No. 4 finish (brushed): Suitable for architectural decoration (handrails, door frames) with a uniform linear texture. 4. HL finish (hairline): Used in high-end decoration and electronic product casings for a fine and elegant appearance.
