SS 321 Stainless steel pipe tube

SS321 is a stabilized austenitic stainless steel with a titanium addition of at least 5 times the carbon content. The addition of titanium reduces or prevents the sensitization of carbide precipitation during welding and when used in the 425-815°C temperature range. It also improves certain properties at elevated temperatures. SS321 has excellent resistance to oxidation and corrosion and has good creep strength. It is primarily used in oil refining equipment, pressure vessel piping, radiant superheaters, bellows and high temperature heat treatment equipment

Kategorie:

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

Zusammensetzung von rostfreiem Stahl

 

Stahl ist eine Legierung aus Eisen und Kohlenstoff. Nichtrostende Stähle sind Stähle mit mindestens 10,5% Chrom, weniger als 1,2% Kohlenstoff und anderen Legierungselementen. Die Korrosionsbeständigkeit von rostfreiem Stahl und

Die mechanischen Eigenschaften können durch Zugabe anderer Elemente wie Nickel, Molybdän, Titan, Niob, Mangan usw. weiter verbessert werden.
