Q690 D/E High Strength Steel Plate | GB/T 1591-2018 Supplier
Q690 D/E is high strength structural steel grade developed for use in the field of construction that needs very high strength, good bearing capacity and light structural weight.
With the yield strength not less than 690MPa, Q690 can provide much higher strength than normal structural steels. It is ideal for heavy duty machinery and engineered components subject to high loads where maximising weight reductions is key.
Q690D and Q690E steel plates are available with Royal Steel Group either in standard or customized sizes for your mining, construction machinery, hydraulic engineering, transportation and other heavy industry applications.

Q690 is available in D and E subgrades, which are selected as per the requirements of the project and service conditions.
Q690D – used in high strength structural applications where improved impact toughness is needed.
Q690E – designed for applications where improved low temperature impact toughness is required.
The choice of grade depends on the relevant design code, service temperature, required impact toughness, welding process and project requirements.
690 MPa Mindeststreckgrenze
The Q690 has a minimum yield strength of 690 MPa which means it can be used for high load items where normal structural steel would mean thicker material.
Strength-to-weight ratios are high
Due to the high strength of Q690, suitable designs can reduce the thickness of components and structural weight but meet the load-bearing requirements.
Heavy-Duty Performance
Q690 steel plate is suitable for high engineering, such as heavy industry hydraulic supports, mining machinery.
Wide Size Availability
Q690 plates can be cut into plates with thickness: 10-80 mm, width: 1220-3048 mm and a standard length from 2438 to 12192 mm.
Tailored Supply
We can discuss tailor made plate size, cutting size, inspection requirements or other processing specifications based on your project.
