The basis of this selection is based on information found on different internet websites including the one from the British Stainless Steel Association.
Not surprisingly, the first grade is 304 (1.4301) and its variants are the most common grades in the SSAS database. This reflects the market as a whole.
Approximate Composition – 18% Cr 8% Ni (exact composition ranges vary between EN and ASTM standards).
This grade combines the following characteristics:
- Good corrosion resistance
- Good weldability
- Excellent ductility giving stretch formability in pressings
- Hygienic surfaces
- Work hardening for spring properties
- Ease of manufacture at the steel mill
This combination of properties leads to the grade being used for a wide range of applications including:
Sinks, pots and pans, catering surfaces, architectural cladding, handrails, food processing, water treatment, pressure vessels, transport containers, surgical instruments, building support products, refrigeration equipment, watch cases, automotive trim, street furniture, anaerobic digestion, chemical plant, sanitary ware.
This is merely a sample of the applications for 304/304L (1.4301/1.4307). Despite the competition from grades with a similar corrosion resistance, this grade is likely to continue to form the backbone of the stainless steel market for some years to come.
Because this is one of the most well known stainless steel grades you will find a lot of products from Shanghai Metal Corporation existing out of this material. For example we offer various Strips / Tapes / Bands and much more using 304 materials.
