SA516 Grade 70 S700MC steel for cranes structure refers to normalized steel products. For steel plates and thin plates with a thickness of less than 40mm, we usually supply rolled steel coils. Plates with a thickness greater than 40mm should be normalized and supplied. The density of S700MC steel for cranes structure SA516 70 grade steel plate is 0.284 cu/in3 (7861 kg/m3).

S700MC steel for cranes structure, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.

S700MC steel for cranes structure, Q345B low alloy plate performance:
1) High strength: Generally its yield strength is above 300MPa;
2) High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600kJ/m to 800kJ/m. For large welded components, higher fracture toughness is also required;
3) Good welding performance and cold forming performance;
4) Low cold brittle transition temperature;
5) Good corrosion resistance.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.

We have huge stocks for carbon steel plates, high strength low alloy steel materials, weather resistant steel sheets, wear resistant steel plates, boiler plates, pipeline steel, etc. Those stocks can be delivered within 10 days after deposit. We update S700MC steel for cranes structure stock list regularly. But the stock changes quickly. It needs to check with warehouse specially when you have urgent needs. Welcome to contact us and book steel materials stocks.
