NEW SCREWS AND BARRELS
 Nitrided screws and barrels |
Screws and barrels are manufactured from 34CrAlNi7 (1.8550) imported from
mainland Europe or 905M39 (EN41B) from the United Kingdom. These components are
manufactured and the screws polished to a very stringent standard. Thereafter, the parts
are Plasma (ion) Nitride hardened to between 1000 and 1200 Vickers (0.1 Hv), with a
penetration of 0.4 – 0.5mm. Screws and barrels ranging from 19mm to 200mm in diameter with a length of up to 4.5m can be manufactured. The refurbishment programme includes a similar range of sizes, except screws with a diameter smaller than 30mm are usually not reconditioned.
