Materials – stainless precision tubes

For available stainless and acid-resistant steel alloys:

AISI 304, W.Nr.1.4301

Analysis: C = 0.07%, Cr = 17-20%, Ni = 8.5 – 10.5%
Stainless steel with good corrosion resistance in normal cold or hot water.
Good cold forming properties.
Used for injection needles, electromedical measuring equipment, etc.

AISI 316, W.Nr.1.4401

Analysis: C = 0.07%, Cr = 16.5-18.5%, Ni = 10.5-13.5%, Mo = 2.5-3.0%
Stainless and acid-resistant steel. Resistant to non-oxidizing acids and chlorine-containing liquids.
Used in the chemical industry, electromedical measuring equipment, etc.

AISI 316L, W.Nr. 1.4404/1.4435

Analysis: C= 0.03%, Cr = 16.5-18.5%, Ni = 12.5- 15%, Mo = 2.5-3.0%
Rust and acid-resistant steel with low carbon content. Increased resistance to intercrystalline corrosion and at higher temperatures.
Used in the electrical industry, temperature sensors, surgical instruments, etc.

AISI 321 / 316Ti, W.Nr. 1.4541/1.4571 

Analysis: C = 0.1%, Cr = 16.5-19%, Ni = 9-13.5%, Ti = 5 x C%.
Titanium-stabilized rust and acid-resistant steel. Resistant to intercrystalline corrosion especially at constant temperatures up to 400 degrees Celsius.
Used in the chemical industry, food and beverage industry
