About 304 stainless steel plate introduction

304 material is the representative grade of stainless steel, with excellent material performance: national standard material, various chemical compositions and mechanical properties meet national standards, dense organization, no pores, no blisters, stable material, excellent performance, and super rust resistance. The most versatile stainless steel.
304 is a general purpose stainless steel that is widely used to make equipment and parts that require a good combination of properties (corrosion resistance and formability).

304 stainless steel is a grade of stainless steel produced according to the American ASTM standard. 304 is equivalent to my country's 0Cr19Ni9 (0Cr18Ni9) stainless steel.

General non-standard material features:
Most of them are made of recycled material doped with primary molten iron, which inevitably contains many impurity elements. Due to the limitation of the production technology level, there are many defects on the surface of the material, and porosity, blisters, etc. are often seen; for the mechanical properties and chemical properties of the material, the corresponding guarantees cannot be obtained, and the batch difference is large, and sometimes it can be seen After the material is turned, fog-like spots often appear on the surface.
Our 304 is different from general materials mainly in the following:
1. There is no peeling and interlayer phenomenon on the surface of the material, the surface is smooth and beautiful, and the lines are clear.
2. The raw materials are all from primary molten iron, which guarantees the quality of the source of raw materials; the ingredients of the batches are completely in line with the national standard.
3. The material is produced in accordance with the national standard technical standards, which strictly guarantees various indicators in the rolling process, and the batch difference of the material is small.
4. The material is treated by aging and high temperature homogenization, which controls the grain size well and ensures the mechanical properties of the material.
5. The material is easy to cut, does not stick to the knife, and the chips are thin strips, which are very suitable for automatic lathe processing and facilitate the realization of automation.
Special Note:
1. During the material cutting process, the speed of the machine tool should be moderate, the cutting edge of the tool should be smooth and sharp, and a reasonable coolant should be selected.
2. Our 304 material has a smooth surface, no black skin, and stable performance. It is recommended that customers choose and use materials according to relevant product requirements.
Common surface features: 2B AB, 6K, 8K, 10K, frosted, brushed, etc.
Varieties and specifications: bars, plates, strips, and other profiles can be customized according to customer requirements.
Typical application areas: Pulp and paper equipment heat exchangers, dyeing equipment, film processing equipment, pipelines, exterior building materials in coastal areas.
