Length

As customer s request

Packaging

Standard export packing, packed in woven bags, with two nylon slings, or can be customized as request

Heat Treatment/      Delivery Condition

1. Cold finished and stress-relieved annealing BKS(+SR)

Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.

1. Annealed    GBK(+A)

The last Cold forming process is followed by annealing in a controlled atmosphere.

1. Normalized   NBK(+N)

2. The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.

Delivery Time

Within 35-50 days from receiving deposit

Payment Term

100% L/C at sight or 30% deposit, 70% balance against copy of B/L

Usage/Application

Pipes for high pressure boiler
