Chanson Metals have various sizes stock of 400 series stainless steel sheet and plate.
409,410,439 are the best material for exhaust pipe.
420J2 is easy to cut and polish, so it is suitable for tools. 420 has excellent rust resistance because of its low carbon content so it’s also an ideal steel for producing diving tools.
430 stainless steel is a general-purpose steel with good corrosion resistance,has better thermal conductivity than austenitic materials. Its thermal expansion coefficient is smaller than austenitic materials,and resistant to fatigue. With ti content make it has good mechanical properties on weld seam. 430 stainless steel is commonly use for building decoration, fuel burner parts, household appliances, home appliance parts.
431 can obtain high mechanical properties after heat treatment, and its corrosion resistance is better than 410 and 430 steel.
440C is mainly used to manufacture bearing parts that work in corrosive environments and in non-lubricating and strong oxidizing atmospheres. 440C has good high temperature dimensional stability and can be used as corrosion resistant high temperature bearing steel. It can also be used to manufacture high quality tools such as medical scalpels, scissors, nozzles, bearings, etc.

Surface Characteristics and Application:
| Surface | Characteristics and application |
| 1D - No. 1 | Hot rolled, metallic pure, annealed, pickled and heat treated. The most common hot rolled finish. A non reflective, rough surface. Not normally used for decorative applications |
| 2D | Matt, cold rolled, annealed, pickled. This material is cold rolled followed by softening and de-scaling. The effect of cold rolling the material is to produce a smoother, less pitted surface. The surface is not only smooth but of matt grain appearance. Used where a better surface is required or subsequent processing/ finishing is necessary. |
| 2B | Matt glossy, cold rolled, annealed, pickled, skinpassed. This is the general purpose, cold rolled finish and it is suitable for a wide range of applications where stainless steel is specified. It is also suitable for a wide range of subsequent polishing processes such as satin finishing and grinding.. |
| 2R - BA | Mirror glossy, bright annealed. The effect of annealing without the presence of oxygen is to produce a reflective surface on the stainless steel and it is often used in preference to a 2B finish where reflectivity is important, such as catering equipment. The very smooth surface also makes this surface highly suitable for further finishing processes such as mirror polishing and chrome plating. |
| 2G- 4N | No. 4 Finish is characterized by short, parallel polishing lines, which extend uniformly along the length of the coil. No 4 finish gives low gloss and best apparent flatness of panels. For fabricators, the No 4 finish is directional, allowing easy matching of surfaces and refinishing of welds. For end users, the surface can be repaired to remove any service damage. No 4 finish is duller than the other common finishes, 2B and BA and is generally used where lower reflectivity or gloss is required and where welds and other fabrication marks are to be refinished to match the original surface. This is not possible with 2B and difficult with BA. |
| Mirror - 8K | #8 mirror-polished is the top quality surface finish. Surface blemishes are eliminated by the complete finishing process to achieve a mirrorlike appearance. Such fine quality can be achieved without any extra finishing or coating materials being added. the characteristics of high reflectivity and a lustrous shine allow them to complete any kind of architectural or interior decoration. |
