Q800D low alloy structural steel
Q800D hsla steel sheet Technical standard: GB/T 16270-2009.
Q800D low alloy structural steel itself not only has very high strength and also has a certain toughness, but also comes with wear resistance, fatigue resistance, impact resistance and welding easy processing performance.
Our Q800D low alloy steel plates can be customised in size, cut, welded and punched according to your end-use requirements for Q800D low alloy structural steel products.
