Grade 42 + Grade 42 Carbon max 0.21% A690 "Mariner" Steel:The Facts [iSheetPile] - Think ASTM A690 (or, Mariner Steel) was created and promoted by US Steel in the 1960s. At the time there was no grade of steel higher than A328 (39 ksi yield strength), and the US Steel sheet piling literature focuses on the fact that, as a stronger grade of steel, A690 (50 ksi yield strength) will be stronger longer than A328 once corrosion sets in (for any environment).
May 30, 2020 · Both ASTM A36 carbon steel and ASTM A572 grade 50 are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 99% of their average alloy composition in common. ASTM A570 GR50 Hot-rolled Carbon structural steel,ASTM ASTM A570 GR50 is a kind of hot-rolled carbon structural steel . There are seven levels or grades in the standard ASTM A570 . They are ASTM A570 GR30, A570 GR33, A570 GR36, A570 GR40, A570 GR45, A570 GR50, A570 GR55 . ASTM A570 GR50 steel is used for formwork board, general machinery and spare parts . Standard:ASTM A570
The ASTM A572 specification is the Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel for plates used in general construction and structural applications. 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 Gr 50 VS A36 steel - BBN SteelASTM A572 Gr 50 steel plate is used in a variety of structural applications including bridges, buildings, construction equipment, freight cars, machinery, truck parts and transmission towers. ASTM A36 steel is used in bolted, riveted and welded processes. Depending on your applications, different steel grades of the two may be used.
ASTM A572 Steel, grade 50, High-strength low-alloy steel, structural quality ASTM A913 / A913M - 19 Standard Specification for High 1.1 This specification covers high-strength low-alloy structural steel shapes in Grades 50 , 60 , 65 , 70 , and 80 , produced by the quenching and self-tempering process (QST). The shapes are intended for riveted, bolted or welded construction of bridges, buildings and other structures.
On one hand, it is similar to A572-50 in low ratio of weight-to-strength. on the other hand, the alloy elements optimize the inside structure of the steel and improves its properties. ASTM A992 Steel I beam is the prime alternative for bridge construction and building frames for its yield strength reaches 65 ksi.

Table 1 Chemical composition of A572 Gr 50 steel as com-pared to A36 steel Chemical Low alloy steel ASTM A572 Gr 50 equivalent material steel Low alloy steel ASTM A572 Gr 50 is considered the "working horse" class and is widely used in in structural applications, heavy construction equipment, building structures, heavy anchoring systems, truck frames, and applications requiring high strength/weight ratios. Low alloy steel ASTM A572 Gr 50 is usually produced into steel plates, channel steel and heavy steel beams.
ASTM A572 was issued as a standaid for the first' time in Sep 2 tember 1966. It covers "Standard Specification for High-StrengthLow-Alloy Columbium-Vanadil:lffi Steels of Structural Quality." Important ASTM Specifications for the chemical compo~iti~nand the mechanical properties of A572 steel-as also of A36, A242, A440 and A441 steels Mechanics of Materials-SteelStructural steels are generally grouped into several ASTM classifications which are identified by the designation assigned by the ASTM. Grade A36 steel with F y =36 ksi and F u = 58 ksi is one of the most commonly mild structural steel used. Other grades used are A572 Grade 50 and A992. More information is
