DIN 17456 standard applies to general purpose seamless circular tubes and pipes made from the stainless steel. The stainless tubes are intended to be used on the basic of an 80% utilization of the permissible design stress in weld such as  construction tubes, pipes for the food, tubes for pharmaceutical industry, pipes for automobile industry, pipes for domestic installation and tubes for decorative purposes.

 

Types and Surface of DIN 17456 Seamless Tubes

Symbol

Type of Condition

Surface Finish

Notes

c1

Hot worked, heat treated, descaled

Metallically clean


c2

Hot worked, heat treatment, pickled


f

Mechanically or Chemically descaled, cold worked, not heat treatment

Metallically bright-drawn, much smoother than for conditions c1 and c2

Cold working without subsequent heat treatment modifies the properties depending on the degree of working; this applies in particular to austenitic steel tubes.

g

Cold worked, heat treated, not descaled

scaled

Suitable only for components which will be descaled or

worked.
