ASTM A815/A815M

ASTM A815 specification covers two general classes, WP and CR, of wrought ferritic, ferritic/austenitic, and martensitic of and welded construction.

Class WP are subdivided into four subclasses: Classes WP-S, WP-W, WP-WX, and WP-WU.

The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. The steel shall be melted by electric furnace, vacuum furnace, or electric furnace followed by vacuum or electroslag-consumable remelting. Forging or shaping operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining or by combination of two or more of these operations. The materials shall undergo heat treatment and shall follow the required cooling process and tempering temperature. Chemical and product analyses shall be performed and shall conform to the required chemical composition in carbon, manganese, phosphorus, silicon, sulfur, nickel, chromium, molybdenum, copper, nitrogen, and titanium. The mechanical properties of the fitting material shall conform to the required values in yield strength, tensile strength, elongation, and hardness.
