Product Description

Different Grades of Stainless Steel

By industry standards, it has several grades to adapt to different use environments. They are:

200 series (Cr-Mn-Ni): 201, 202

• 300 series (Cr-Ni): 301, 302, 303, 304, 304L, 304N, 309, 309S, 310, 316, 316L, 321, 347
• 400 series (Cr): 408, 409, 410, 416, 420, 430, 440

Below is a table showing the different compositions.

Surface Finish Types

• NO.1: Rough surface, presence of oxidized skin and indentation, can be further processed.
• 1D: hot rolled + annealed + pickled process, retaining hot rolled texture.
• 2D: cold rolled + heat treatment + pickling, suitable for deep drawing process, matte surface.
• 2B: 2D based on more bright processing, smooth surface slightly reflective.
• NO.3: for a polished surface, the surface can be seen with fine polishing grains.
• NO.4: frosted surface, friction resistant and fingerprint resistant.
• 8K: Mirror polished, highly reflective.
• HL: brushed surface is unidirectional fine brushed texture, anti-scratch.
•  

Application Uses

Recommended Surface Scenarios

1. BA, 8K: highly reflective/decorative scene.
2. 2B, NO.4: Durable/resistant to polluted environments.
3. NO.1, 1D: Industrial processing/structural parts.
4. HL, NO.3: Applications requiring anti-slip/abrasion resistance.
5. BA (inside), 2B (outside): Special environments (chemical/high temperature).

Application Areas

1. Food processing: beer brewing, milk processing and wine making.
2. Medical equipment: scalpels, biological implants such as steel nails, leads, dental trays, tweezers.
3. Industrial applications: heat exchangers, containers, pipes. , paper making machinery, etc.
4. Transportation applications: Used in automotive exhaust pipes, fuel lines, and body parts. It is used in the shipbuilding industry for hulls and cabins, engine parts, turbine blades, and gas turbines.
5. Family application: It is widely used in kitchen utensils such as pots, pans, plates, cutlery, etc. It is also used in sanitary equipment such as faucets, bathtubs, toilets, and so on.
6. Building applications: such as doors, windows, railings, and stair handrails. It is also used for structural supports, frames, and connectors.
