The characteristics of SS321 stainless steel pipe are as follows:
High temperature resistance: SS321 stainless steel has excellent high temperature resistance and can withstand corrosion and oxidation in high temperature environment for a long time.
Corrosion resistance: SS321 stainless steel has excellent corrosion resistance and can resist corrosion in many chemical environments, including organic acids, alkalis and solvents.
Oxidation resistance: SS321 stainless steel has good oxidation resistance, can resist high temperature oxidation and extend service life.
Processing performance: SS321 stainless steel has good plasticity and weldability, and is easy to process into various shapes and sizes.
Mechanical properties: SS321 stainless steel has high tensile strength, yield strength and impact toughness, suitable for various engineering and structural applications.
Chemical element composition content: The chemical element composition content of SS321 stainless steel includes chromium (Cr), nickel (Ni), iron (Fe) and titanium (Ti). The proportion and combination of these elements give SUS321 stainless steel high temperature resistance, corrosion resistance and oxidation resistance.
Characteristics at high temperatures: SS321 has excellent resistance to oxidation and corrosion, and has good creep strength. It is mainly used in oil refining equipment, pressure vessel pipelines, radiation superheaters, bellows and high-temperature heat treatment equipment.
Resistance to intergranular corrosion: Due to the addition of titanium, SS321 stainless steel has better resistance to intergranular corrosion and high-temperature strength

Composition de l'acier inoxydable
L'acier est un alliage de fer et de carbone. Les aciers inoxydables sont des aciers contenant au moins 10,5% de chrome, moins de 1,2% de carbone et d'autres éléments d'alliage. La résistance à la corrosion de l'acier inoxydable et
Les propriétés mécaniques peuvent être encore améliorées par l'ajout d'autres éléments, tels que le nickel, le molybdène, le titane, le niobium, le manganèse, etc.
