ASTM A441, used in low-tolerance, state-of-the-art structures, such as towers and large telescopes, SA573 Grade 70 export is a high-strength structural grade with a yield strength of 40,000 to 50,000 psi and an allowable bending stress of 24,000 to 30,000 psi.
There are many advantages of SA573 Grade 70 export, pickling coils. The surface of pickling coil is smooth, and the outside is very beautiful. From the appearance, we can see how the manufacturer's technology is, and it is convenient to use pickling coils in engineering. In addition, the cost can be reduced by using pickling coil instead of cold rolled sheet. The corrosion resistance of pickling coil is better than ordinary steel plate, and its service life is also very long.
The microstructure of the quenched and tempered alloy steel, SA573 Grade 70 export after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0). According to EN 10025-2, the thickness of S450J0 plate is within 3-150mm. The SA573 Grade 70 export, S235 steel, S275 steel and S355 steel plate thickness is ≤250mm. However, the S235J2, S275J2, S355J2 and S355K2 plates limitation is ≤400mm.
If you are in the search of best quality of SA573 Grade 70 export structural steel plate then you have landed on the right place. These high quality structural steel plates are used for a long time as they have a long life due to their best and advance manufacturing techniques. These SA573 Grade 70 export plates are best and ideal for temperature rise work, high pressure and tank fabrication work where accurate & excellent toughness is required for better results.
