ASTM A – Table 4 – Tolerances? – ASTM (testing materials) Code Issues – Eng-Tips
It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet. The Eng-Tips staff will check this out and take appropriate action.
Super Duplex and Duplex Brand: Promoting, selling, recruiting, coursework and thesis posting is forbidden. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. Close this window and log in.
Stainless Steel – Duplex – ASTM A ~ S
Class WP fittings are subdivided into four subclasses: The mechanical properties of the fitting material shall conform to the required values in yield strength, tensile strength, axtm, and hardness. Duplex steels are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless.
Join your peers on the Internet’s largest technical engineering professional community. Fabrication of all stainless steels should be done only with tools dedicated to stainless steel materials.
Chemical and product analyses is performed and is conform to the astn chemical composition in carbon, manganese, phosphorus, silicon, sulfur, nickel, chromium, molybdenum, copper, nitrogen. My customers are mainly in South America. We also provide Standard certificates like EN 3.
I have attached Table 4 as a JPG for review.
ASTM A815 Pipe Fittings
So, theKSI for them is the same as SS Pipe Fittingss is non-hardenable by heat treatment. The materials shall undergo heat treatment and shall follow the required cooling process and tempering temperature.
Where we use a period between whole numbers and decimal places, they use commas. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.
Offer on Fasteners Sitemap. We are the exporter and manufacturer of these pipe fittings which are high quality and provides high mechanical strength, good weldability and good corrosion resistance. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. The mechanical properties of the fitting material shall conform to the required values in yield strength, tensile strength, elongation, and hardness.
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.
No liability will be accepted by the Company in respect of any action taken by any third party in reliance thereon. Red Flag This Post Please let us know here why this post is inappropriate. 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. 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.
