ASTM 304L - EN 1.4307

Essential details
The steel grade 1.4307 (also called ASTM 304/ 304L – SS2333) is a general purpose stainless steel, called 18-8-steel, with good corrosion resistant, impact strength and formability.

The steel has improved machinability by MAXIVAL®, and it is suitable for production of corrosion resistant products by machining. It has good corrosion resistance to uniform corrosion and to many slightly corrosive organic and inorganic chemicals. It is non-magnetic but may become somewhat magnetic after cold working and welding.

Typical Application:

- Construction

- Building

- Reinforcement

- Machining

- Bolts

- Fittings
