These are chromium and nickel containing alloys with some grades containing molybdenum additions. They are non-magnetic, but can become slightly magnetic when cold worked. Cold working also enhances their strength. Austenitics have excellent corrosion resistance; good formability; good weldability, and excellent mechanical properties over a wide range of temperatures. In addition, these steels are easy to clean, which enhances their use in applications in hygienic and sterile environments.

Dimension: OD(6-630)*sch(10-160)*length(4000-13000)

Typical applications for the various types include:

304/304L

Tanks, storage vessels and pipe work for corrosive liquids. Process equipment in the mining, chemical, cryogenic, food, beverage and pharmaceutical industries. These stainless steels are also used for manufacturing hollowware, cutlery, architectural products and sinks.

309S/310S

These grades have a higher nickel and chrome content than the 304 grade. As a result of their high oxidation resistance, these steels are used for high temperature applications such as furnace and kiln components.

1.4828

These grades have a high nickel, chrome and silicon content. As a result of their high oxidation resistance, these steels are used for high temperature applications such as furnace, kiln and catalytic converter components.

316/316L

Tanks, pressure vessels, pipe work and components for more aggressive conditions and specialised applications, such as the manufacture of tank containers for bulk transportation of chemicals and corrosive liquids. Molybdenum is added to enhance corrosion resistance.

321/316Ti

These types are used in components which require elevated temperature strength and corrosion resistance, such as afterburners, super heaters, compensators and expansion bellows.
