Product Detail

Shanghai Metal Corporation is a professional manufacturer and supplier of 18Mn2CrMoBA (HB5269-83) high quality structural steel for aviation with high quality and reasonable price.

SMC is a professional manufacturer of high quality structural steel for aviation. HB5269-83(high quality structural steel bar for aviation), Q/6S9-86(18Mn2CrMoBA steel plate), Q/6S7-68(GC-11 steel seamless structural steel pipe technical conditions) and other professional production enterprises, product quality is stable and reliable, trusted and recognized by customers.

If you would like to know more about the prices of our submarine steel plates, please feel free to contact us and we will get back to you within 24 hours.

18Mn2CrMoBA is a low alloy high strength bainite steel, air quenched and tempered with 30CrMnSiA steel has the same comprehensive mechanical properties, because of high hardenability, it can be used air quenched, not only simplifies the heat treatment process, but also reduces the deformation of parts, has a high tempering resistance, good stamping performance and welding performance, welding crack tendency is small.

1. Standard: HB5269-83，Q/6S9-86，Q/6S7-68，GC-11，18Mn2CrMoBA

2. Thickness: 10mm-35mm, 36mm-70mm, 5mm-9mm

3. Yield strength σs (MPa) : 590 ~ 745;

4. Elongation δ5 (%) : ≥16;

5. Section shrinkage (%) : ≥50;

6. Impact attack αk (J/cm2) : ≥80;

7. Fiber section ratio Fa% : ≥100

The steel has high hardenability and can be air quenched, which not only simplifies the heat treatment process, but also reduces the deformation of parts. It also has high tempering resistance, good stamping performance and welding performance, no heat treatment after welding, the strength of the weld and the matrix after air quenching, small welding crack tendency, and can manufacture any complex welding components. If surface protection is required, it can be galvanized according to the general cyaniding method.

Low alloy high strength bainite steel
