Class WP-S fittings are those manufactured from seamless product by a seamless method of manufacture marked with class symbol WP-S ; Class WP-W fittings are those which contain welds where the fitting fabrication or construction welds have been radiographed marked with class symbol WP-W ; and Class WP-WX fittings are those which contain welds where all welds have been radiographed marked with class symbol WP-WX ; and Class WP-WU fittings are those which contain welds where all welds have been ultrasonically tested marked with class symbol WP-WU.

But if you had parts forged then they should have been reheat treated, and then retested.

ASTM A – Table 4 – Tolerances? – ASTM (testing materials) Code Issues – Eng-Tips

Duplex stainless steels are in most cases, tougher than ferritic stainless steels. Forging or shaping operations are performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining or by combination of two or more of these operations.

Whilst duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels. Where we use a period between qstm numbers and decimal places, they use commas. Defense manufacturing is all about project manufacturing and project accounting. Referenced Documents purchase separately The documents listed below aetm referenced within the subject standard but are not provided as part of the standard. The Eng-Tips staff will check this out and take appropriate action.

The mechanical properties of the fitting material shall conform to the required values in yield strength, tensile strength, elongation, and hardness. Are you an Engineering professional? Super Duplex and Duplex Brand: Looking for some more information? Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. There are rules for tolerances on values as far as decimal places, but yes your value would round OK.

Duplex steels are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless. It is used in umbilicals, storage tanks and pressure vessels. The materials shall undergo heat treatment and shall follow the required cooling aastm and tempering temperature. The steel shall be melted by electric furnace, vacuum furnace, or electric furnace followed by vacuum or electroslag-consumable remelting.

As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. Work Item s – proposed revisions of this standard. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Class WP fittings are subdivided into four subclasses: I have attached Table 4 astmm a JPG for review. Download Now White Paper: These precautions are necessary to avoid cross contamination of stainless steel by easily corroded metals that may discolour the surface a185 the fabricated product.
