When we talk about the material of steel pipe fittings,  we talk the material steel grade , for example,  ASTM A234 WPB or A403 WP316L.

It is the material information of this fitting , not the raw material steel grade for fittings production .  A butt welding steel elbow, 6″ SCH40, the material is ASTM A234 WPB,  as we know, it is produced from a steel pipes. The raw material is a steel pipe, the steel grade may be ASTM A106 Gr.B , or A53 GR.B ,  not the pipe of A234 WPB .

Before the production  of an steel pipe fitting of a specific material , we should confirm the raw materia steel grade first , make sure the fittings from this raw material is absolutely as per the fittings materail technical requirements, such as the Chemical composition, Mechanical property, or the heat treatment data .
