The Relationship Between Chemical Composition, Organization And Properties Of Stainless Steel

Stainless steel as a steel material, the content of the study is also the (chemical) composition of steel - organization (structure) - (various) properties of the relationship between, in fact, this middle involves both heat treatment, but also involves a variety of processing, while the purity of stainless steel, uniformity, surface condition, etc. also has an important impact.

To study and understand the stainless steel, in fact, both to understand the composition of stainless steel - organization - performance of the relationship, but also to understand the heat treatment - organization - performance of the relationship and processing - organization - performance of the relationship and the purity of the steel, uniformity, and the impact of the surface condition.

1. Stainless steel corrosion resistance is mainly determined by the chemical composition of the steel (at present, it is popular in the community only with or without magnetism to determine the advantages and disadvantages of stainless steel corrosion resistance is unscientific. Because the magnetism of stainless steel is the organizational structure of steel is determined).

2. Under the influence of some conditions (such as thermal history), the interaction between the chemical composition of steel, both to determine the type of steel matrix organization, and to determine the composition of various phases and compounds of steel (in fact, the non-metallic inclusions in steel also belong to the product of the interaction of chemical elements in steel).

3. The mechanical and physical properties of stainless steel are mainly determined by the organizational structure of steel.

4. The chemical composition of stainless steel can also directly affect the mechanical properties of steel, such as alloying elements of solid solution strengthening. The organizational structure of stainless steel can also directly affect the corrosion resistance of steel, such as carbon, oxides and intermetallic compounds precipitation effect.

5. Under some conditions, the corrosion resistance of stainless steel and mechanics and some other properties can also affect each other.

6. In addition to the chemical composition and organizational structure of stainless steel, stainless steel purity, uniformity, surface condition of stainless steel also has an important impact on the performance.
