SS 321 Stainless steel bar bars

SS321 stainless steel 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

The characteristics of SS321 stainless steel bar are as follows:

High temperature resistance: It has excellent high temperature resistance and can withstand corrosion and oxidation in high temperature environment for a long time.

Corrosion resistance: It has excellent corrosion resistance and can resist corrosion in many chemical environments, including organic acids, alkalis and solvents.

Oxidation resistance: It has good oxidation resistance and can resist high temperature oxidation and extend service life.

Processing performance: It has good plasticity and weldability and is easy to process into various shapes and sizes.

Mechanical properties: It 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 SS321 stainless steel high temperature resistance, corrosion resistance and oxidation resistance 3.

Strength and hardness: It has relatively high strength and hardness, which makes it perform well in some applications that require high strength and compressive resistance 1.

Ductility and stress fracture resistance: Compared with 304 alloy, it has better ductility and stress fracture resistance, and has better creep stress resistance and stress fracture resistance1.

Organization structure: As a duplex stainless steel, the organization structure of SS321 contains austenite phase and ferrite phase, which makes it have good corrosion resistance and strength1.

Application field: It is commonly used in chemical equipment, petrochemical equipment, food industry equipment and other fields under high temperature. It can also be used in aircraft, exhaust pipes, boiler drums, etc.; it is also widely used in chemical, petroleum and pharmaceutical fields.

Composição do aço inoxidável

O aço é uma liga de ferro e carbono. Os aços inoxidáveis são aços que contêm pelo menos 10,5% de crómio, menos de 1,2% de carbono e outros elementos de liga. A resistência à corrosão do aço inoxidável e

As propriedades mecânicas podem ser melhoradas pela adição de outros elementos, como o níquel, o molibdénio, o titânio, o nióbio, o manganês, etc.
