By using TP 304L you get a corrosion resistant austenitic stainless steel with good formability. The steel is modified for machining and is available in a wide range of profiles and dimensions. The steel is often used for details within building and construction, machining industry.
The steel grade TP 304L (also called 1.4307) is a general purpose stainless steel, with good corrosion resistant, impact strength and formability. The steel 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 areas for TP 304L:
- Construction
- Building
- Reinforcement
- Machining
- Bolts
- Fittings
Certificate
The steelworks has certificate as an approved material supplier of this steel grade from ABS, BV, DNV-GL, TUV, LR,KR and CCS.
