Why should you use BS EN 4334 - Steel filler metal for welding for aerospace application?
There are many considerations to make when creating parts for aerospace applications, such as the shape, weight, and durability of a part. These factors can all affect the aircraft’s flight worthiness. When designing the interiors or exterior of vessels such as airplanes, spaceships, submarines, etc., structural decisions are based on function. There are some specific applications where aerospace-grade stainless steel may surpass aluminum in performance. For years, the go-to material for aerospace applications was aluminum. However, in recent years, aerospace manufacturers have started investigating alternatives to aluminum, one of them being aerospace grade stainless steel.  
BS EN 4334 provides you with requisites and standards for steel for aerospace applications so that the products are suitable for the required purpose. 
The guidelines in BS EN 4334 contribute towards including high-quality components for aerospace that are responsible for the smooth and safe functioning of vessels.
