two grades (ASTM A36 and ASTM A572 Grade 50) of structural steels, based on mill test reports from selected domestic producers for the 1992 production year. Data were also collected for "Dual Grade" material that was certified by the producers as complying with both ASTM A36 and ASTM A572 Grade 50. API 2W Grade 50 TMCP Offshore Steel PlatesOffshore steel plate to API 2W Grade 50 is kept in stock. Our plates are to a modified version of the API 2W-50 standard produced by Dillinger which provides improved performance. The API 2W grade 50 plates are all to 3.2 MTC and are produced by a G7 mill, Dillinger Hutte.The steel is made in Dillingen in Germany and then rolled in either Germany or France depending on the thickness or the

ASTM A572 - SSAB

ASTM A572. The ASTM A572 specification is the Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel for plates, structural shapes, sheet pilings and bars. ASTM A572 includes five grades with specified minimum yield strengths of 42, 50, 55, 60, and 65 ksi, respectively. For applications where notch toughness is important, consult SSAB for specific Charpy V-notch toughness ASTM A572 Grade 50 high strength low alloy Pipe Gr. 42 The grades in this specification will co-relate to the strength. For instance, the strength of ASTM A572 Grade 50 HSLA Pipe is about 380 Mpa. Similarly, the strength of grades 42, 55, 60 & 65 in Mpa are as follows - 290, 380,415, and 450. Typically, the use of high-strength low-alloy or HSLA ASTM A572 Grade 55 is intended for applications in ASTM A572 Grade 50, 55, 60, 65 Steel Plates Specification A:Specimen shall comply with Specification of A6/A6M. B:Elongation not required to be determi ed for floor plate. C:For wide flange shapesover 426 lb/ft [634 kg/m], elongation in 2 in. [50 mm] of 19% minimum applies. D:For plates wider than 24 in. [600 mm], the elongation requirement is reduced two percedntage points for Grade 42, 50, and 55 [290,345,and 380], and three percentage points

Q:We manufacture structures for the utility industry and primarily weld A36, A572-Gr. 50 and A871-Gr. 65. Recently we converted some of our welding processes to higher-deposition submerged-arc welding (SAW) but are concerned about the amount of heat we are adding from welding.

    Normalized A572 Gr 50? - Metal and Metallurgy engineering

    May 17, 2007 · Originally, the A572 50 did not require impacts or hardness, so the PQR for this job was qualified using A572 50 (as rolled) to 8630M; the 8630M pasted the CVN test at 31/24 ft-lbs. @ -4 F, and the A572 failed (PWHT on PQR [1125 F for 4.5 Hrs]). I was aware that A572 50 does not do very well when stress relieved for that period of time. Notch Toughness - an overview ScienceDirect TopicsImpact testing frequency for Class C steels should be in accordance with the specification under which the steel is ordered; in the absence of other requirements, heat lot testing may be used. ASTM A572 Grade 50, to 50 mm thick (S91 required over 12 mm thick) 345:450 min:ASTM A992:345450: If a welding procedure requires impact Fracture Toughness of A572 Gr.50 Steel Built-Up Box The A572 Gr.50 steel absorbs energy more than 105J, satisfying the code requirement of 27J at 0°C in the Charpy impact tests. However, the welding heat increases the size of coarse grain and hardness in the heat affected zone (HAZ), reducing the Charpy value to 14.9 J.
