With good product A573 grade 70 structural steel plate quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.
20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. A573 grade 70 structural steel plate, 20# steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥24%. 20# steel performance is basically similar to 15# steel, but the strength is slightly higher. The cold-drawing or normalizing state of the cutting process is better than the annealing state. 20# steel is used to manufacture various mechanical parts with high toughness under hot rolling or normalizing state, which require high toughness.
Heat treatment advantages of A573 grade 70 structural steel plate, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.
The work performance of A573 grade 70 structural steel plate etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.
Mechanical Properties A588 corten steel: ASTM A588 Grade A is a high-strength, low-alloy steel plate utilized primarily in structural applications such as bridges and buildings. We stock this material as A588 Gr A & B in plate and 606 in sheet. Tensile: 70 ksi min (4” and under), 67 ksi min (4”-5”) 63 ksi min (over 5”-8”) Yield:50 ksi min (4” and under), 46 ksi min (4”-5”) 42 ksi min (over 5”-8”) Elongation:16% min in 8” 19% min in 2” (for plates wider than 24”)
