ASTM A815 Wrought Ferritic, Ferritic/Austenitic, and Martensitic Stainless Steel Piping Fittings Class WP fittings are subdivided into four subclasses: Class WP-S fittings are those manufactured form seamless product by a seamless method of manufacture;Class WP-W fittings are those which contain welds where the fitting fabrication or construction welds have been radiographed;Calss WP-WX fittings are those…
We normally use A240 S32205 or S32750 steel plates to manufacture welded pipe fittings, and the thickness of the steel plates needs to be checked when purchasing. Then what is the thickness tolerance of the above two kinds of steel plates? This tolerance is derived from ASTM A480, see figure below: Inch Size Metric Size
ASTM A480/A480M General Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip Ordering InformationIt is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under this specification. Such requirements may include, but are not limited to, the following:

S32205 of ASTM A276 – Stainless Steel Bars and Shapes Scope of ASTM A276This specification covers hot-finished or cold-finished bars except bars for reforging (Note 1). It includes rounds,squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels. The free-machining types (Note…
The customer’s drawing is a welded part, we think it is better to make an integral flange, no weld, but also save the cost of secondary heat treatment. After communication with the customer, the customer changed the drawing and changed the duplex stainless steel welding part into an integral forged long weld neck flange. Customer’s…
