What is BN2?

Baseler Norm 2 (BN2 for short) is intended to ensure that uniform corrosion resistance can be assumed even when products of different origin and batches are used. This standard describes the technical material requirements for products made of austenitic, stainless steel with molybdenum, based on 1.4435 steel (X2CrNiMo18-14-3) according to EN 10088, prEN 10028-7 as well as DIN 17440 and 316L (AISI), but with narrower analytical limits and defined ferrite content (< 0.5%).

What is the alloy surcharge?

The alloy surcharge is a part of the sales price, which is charged by stainless steel dealers in addition to the basic price. The alloy surcharge is valid for one month and depends on the price development on the London Metal Exchange of the alloying elements added to stainless steels: chromium, nickel, titanium, molybdenum and niobium. 
As there have been strong fluctuations in the last few years, Dockweiler decided to add this surcharge only for the tubes group of products. For fittings, this price is already included in the list prices. Alloy Surcharges

What is the difference between conventional orbital welding and the Dockweiler IO welding process?

In conventional orbital welding technology, welding is performed from the outside using welding guns. In the Dockweiler IO welding process, however, welding is performed from the inside. The advantage of this is production with very low dead space. In IO welding technology, inner diameters of 4 mm or larger can be welded.
