Shipping and delivery problems: EPT tubes are sent in adhering to situations (first image lists earlier designation, the new one in accordance to EN is in brackets):
BK ( C) Cold concluded/tough (cold completed as drawn).
No heat remedy right after last chilly forming procedure.
BKW ( LC) Cold finished/soft (flippantly cold worked).
After last warmth remedy there is a light finishing pass (cold drawing).
BKS ( SR) Chilly finished/pressure reduce annealed.
Right after the last chilly forming method the tubes are tension relieve annealed.
GBK ( A) Annealed.
Soon after the ultimate chilly forming procedure the tubes are annealed in a managed ambiance.
NBK ( N) Normalized.
Following the final chilly forming method the tubes are annealed previously mentioned the higher transformation stage in a managed ambiance.
