1.4404/ 1.4401 (ASTM 316/ 316L – ≈ SS2348)

By using 1.4404  (ASTM 316/ 316L – ≈ SS2348) you get a corrosion resistant austenitic stainless steel with good formability. The steel is modified for machining and has very good corrosion resistance. The steel is often used for details within building and construction, process industry.

The steel grade 1.4404  (also called ASTM 316/ 316L and ≈ SS2348) is a stainless ” acid-proof” steel which is easy to machine. The steel has improved machinability by, MAXIVAL®, and it is suitable for production of corrosion resistant products by machining.  1.4404 has a very good corrosion resistance which make it useful within a wide range of areas. It has an improved resistance to pitting and crevice corrosion in environments containing chlorides, due to the addition of moybdenium. It is non-magnetic but may become slightly magnetic after cold working and welding.

Typical application areas for 1.4404:

  • Construction
  • Building
  • Process Industry
  • Reinforcement

Easy to weld and machine

1.4404 can be readily welded by a full range of conventional welding methods. It  cannot be hardened by heat treatment, but it can be hardened by cold working. Thanks to MAXIVAL® the steel is easy to machine and has significantly better machining properties compared to common austenitic steels.

The steelworks has certificate as an approved material supplier of this steel grade from ABS, BV, DNV, GL, Lloyd’s and RINA.
