You do NOT haveksi, but rather psi.

But if you had parts forged then they should have been reheat treated, and then retested. Even in chloride and sulphide environments, duplex stainless steels exhibit very high resistance to stress ast cracking.

Link to Active This link will always route to the current Active version of the standard.

The asfm shall be melted by electric furnace, vacuum furnace, or electric furnace followed by vacuum or electroslag-consumable remelting. Super Duplex and Duplex Brand: Any help would be most appreciated! The materials shall undergo heat treatment and shall follow the required cooling process and tempering temperature. Siddhagiri Metals and Tubes Manufacturer: Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

Click Here to join Eng-Tips and talk with other members! So, theKSI for them is the same as The steel shall be melted by electric furnace, vacuum furnace, or electric furnace followed by vacuum or electroslag-consumable remelting.

All standard welding processes can be used. ASTM standards generally consider yield and tensile stresses to be rounded to the nearest ksi, so yourwould round to ksi and would meet the criteria in the standard barely. I want to ask the experts out there a question pertaining to common ASTM practices. Download Now Defense manufacturing is all about project manufacturing and project accounting.

Within the text, the SI units are shown in brackets. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. Stainless Steel Seamless Pipe Fittingss have very excellent drawability, where grouping of low yield power and high elongation allows an effective forming of multifaceted shapes. No liability will be accepted by the Company in respect of any action taken by any third party in reliance thereon.

This means coolants and lubricants are necessary and must be used in large quantities. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. At low temperatures duplex stainless steels have w815 ductility than the ferritic and martensitic grades. Duplex stainless steels are extremely corrosion resistant, work hardenable alloys.

Tooling and work surfaces must be thoroughly cleaned before use. Register now while it’s still free! Hello All, I am not a engineer, but a purchaser of steel pipe and fittings.

ASTM A Duplex Steel and Super Duplex Pipe Fittings Supplier

It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet. I had a metal fabricator create several swage nipples from round bar, material S No guarantee is given that the information is from the latest issue of those sources or about the accuracy of those sources.

The Eng-Tips staff will check this out and take appropriate action. Terms of Asstm Privacy Policy. They have high resistance to intergranular corrosion. Class WP fittings are subdivided into four subclasses: Red Flag This Post Please let us know here why this post is inappropriate.

Current News Archive Standard Technically. Referenced Documents purchase separately Xstm documents listed below are referenced within the subject standard but are not provided as part of the standard. They are not quite as easily welded as the austenitic grades but low thermal expansion in duplex grades reduces distortion and residual stresses after welding. Are you an Engineering professional? Historical Version s – view previous versions of standard.

  AN INTRODUCTION TO THEORIES OF PERSONALITY HERGENHAHN PDF

It is used in umbilicals, storage tanks and pressure vessels. Fabrication of all stainless steels should be done only with tools dedicated to stainless steel materials. The materials undergo heat treatment and follow the required cooling process and tempering temperature. In particular, mechanical property requirements vary widely with temper, product and product dimensions.

This abstract is a brief summary of the referenced standard. Chemical and product analyses is performed and is conform to the required chemical composition in carbon, manganese, phosphorus, silicon, sulfur, nickel, chromium, molybdenum, copper, nitrogen.

Chemical and product analyses shall be performed and atm conform to the required chemical composition in carbon, manganese, phosphorus, silicon, sulfur, nickel, chromium, molybdenum, copper, nitrogen, and titanium.

I have attached Table 4 as a JPG for review. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. All information is based on our present knowledge and is given in good faith.

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. The strip sections in Stainless Steel EFW Pipe Fittingss may be air cooled, but heavy sections of the same should be water quenched to minimize exposure in satm carbide precipitation region.
