ASTM A516 Grade 70 or ASME SA 516 grade 70 is one of the most popular steel grades. It is primarily intended for use in welded pressure vessels where notch toughness is important. These grades cover a range of tensile strengths from 55 - 90 MPa and this versatility A516-70N MDMT without impact test in ASME BPVC VIII May 07, 2012 · My API-650 2008 edition "Welded Oil Storage Tanks Standard" for A 516 Gr 70, Group V steel, at 1.25" thickness must be impact tested below 12 deg F. Yes, there is a difference and the reason is because API 650 requires higher threshold impact energy for Group V steels - 30 ft-lbs for 1.5" thick or less versus Section VIII, which requires only 15 ft-lbs at the MDMT.
In the above example (normalized SA 516 Gr.70, Curve D, 1.125 inch thickness), the minimum permissible temperature without impact test is -26 degree F. This means that, if in the above example your MDMT changes from -20 degree F to -27 degree F, then you cannot be exempted from the ASME impact test requirement by UCS-66(a), and you have to proceed to UCS-66(b) ASTM A516 / A516M - 17 Standard Specification for A516 / A516M-17 Standard Specification for Pressure Vessel Plates, Carbon Steel, for Moderate- and Lower-Temperature Service pressure vessels~ welded ASTM A516 Carbon Steel, Grade 70ASTM A516 Carbon Steel, Grade 70 Categories:Metal; Ferrous Metal; Alloy Steel; Low Alloy Steel; ASTM Steel; Carbon Steel; Low Carbon Steel.

Jul 12, 2009 · A516 GR. 70 is a High Tensile Low Alloy PLATE Material Grade Whereas A350 LF2 N CL2 is a FLANGE forging Material grade under normalized Condition. A350 LF2 N CL2 is not equivalent to A105N. A350 LF2 N CL2 is a material grade with chemical properties suitable to LOW TEMPERATURE ranging from -50°F up to +4°F ASTM A516/ ASME SA516 steelASTM A516/ ASME SA516 SA516 is a carbon steel plate grade utilized primarily in welded pressure vessels for moderate to lower temperature service. This material is produced in grades 55, 60, 65 and 70. This material is also offered in the normalized condition where improved notch toughness is required. ASTM A536 Standard for Ductile Iron CastingsGrade 60-40-18 Grade 60-42-10 Grade 65-45-12 Grade 70-50-05 Grade 80-55-06 Grade 80-60-03 Grade 100-70-03 Grade 120-90-02. This specification covers castings made of ductile iron, also known as spheroidal or nodular cast iron, or S.G. iron. The followings are the main content for mechanical, chemical requirements, and also quality requirements. 1.
Aug 26, 2016 · A537 Cl 1 (less than 2-1/2") has an allowable strength at those temperatures of 20,000 psi; BUT, this depends on the applicable, if any impact testing, which depends on the thickness of the material. A516 Gr. 70 (with impact testing for those temperatures) has an allowable strength of 20,000 psi. Lastly, both materials have a P-No of 1 and Group-No 2; which means they are similar materials Comparing Steel Plate GradesA516 GR 70:This grade 70 steel plate possesses good strength characteristics. The silicon killed deoxidization process ensures an even consistency in the finished product. It also has a finer grain and notched toughness. SA537:Plate made of Pressure Vessel Quality grade. It is typically used for manufacturing fusion welded pressure vessels HAZ impact properties of SA-516 Gr.70 weld, and And also the HAZ impact test requirements about surveillance tests in nuclear reactor vessels were compared and investigated. And the effects of the notch location and specimen direction on impact
Aug 05, 2016 · As per our client requirement , impact testing at 20 deg C required for SA 516 Gr70 plates but one of our fabricators did testing at 0 deg C. As far I know testing at lower temperatures are acceptable but how to interpret the obtained values with the required values. For Example our requirement is 37Joules for 3 specimens in transverse specimen at 20 deg C but the obtained value is SA516 GR.60/70N Dual Certified Plates Supplier, Stockist ASTM A516 GR.60/70N Boiler Quality Plates US $800-4000 / Metric Ton( FOB Price) SA516 Grade 60/70N Lower-Temperature Dual Certified Plates US $500-800 / Metric Ton( FOB Price) Export Quality ASME SA516 GR.60/70N Carbon Steel Plate US $560-670 / Ton( FOB Price) A516 Grade 60/70N HR BQ Plates US $500-900 / Ton( FOB Price) SPECIFICATION FOR PRESSURE VESSEL PLATES, CARBON Mechanical Test Coupons, S4.1 Additional Tension Test, S5.

Mar 22, 2007 · A-516 Gr 70 is a low carbon, fine grain steel suitable for low temperature service. It's easy to weld with SMAW and MIG. Mechanical tests usually include bending, tensile and impact (Charpy, as they say in the USA) tests. The HAZ is roughly divided in three sections: Charpy V-Notch Impact Test for ASTM A516 PlatesThe Charpy V-notch impact test for ASTM A516 Gr.65 plate. According to ASTM A20, ASTM A516 Gr. 55, Gr. 60, Gr. 65 plates are Class III steels which are killed with a specified minimum tensile strength of 65 ksi or lower. ASTM A516 Gr. 70 plates are Class IV steels which are killed with a specified minimum tensile strength of over 65 ksi to 75 ksi.
