With the addition of molybdenum, A4 stainless (ASTM 316) is significantly more resistant to corrosion than the more popular A2 (ASTM 304) and very little more expensive. Although A4 stainless is often referred to as marine grade Challenge Europe have noticed an increasing need for this highly cost-effective grade to meet the demands of non-marine industries where equipment is subjected to more demanding service conditions. The non-magnetic nature of A4 also makes it particularly suitable for use in instrument manufacture and the medical industry. Consequently, Challenge are pleased to announce ranges of ex-stock nuts, bolts, screws and washers in A4 stainless for manufacturing and service/maintenance requirements.
The exceptionally high quality and longevity of A4 grade fasteners makes them a firm favourite in UK industry. Now coupled with a service package such as Kanban, Lineside supply or Vendor Managed Inventory (VMI), Challenge Europe are able to provide design and production engineers with the fasteners they want at prices they need – and to work with purchasing departs so as to ensure smooth assembly flows.
