How to cut S690QL1 1.8988 high strength steel plate

The company has allocated special environmental protection facilities for all S690QL1 1.8988 high strength steel plate pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, S690QL1 1.8988 high strength steel plate steel mill scale, environmental protection dust has reached 100%.

The five advantages of S690QL1 1.8988 high strength steel plate wear-resistant steel plate can reduce its own weight. The steel plate is designed according to the addition of several required alloy elements. Through the special heat treatment method of steel plate, the strength level of S690QL1 1.8988 high strength steel plate steel plate is improved to make it have high hardness (wear resistance) corresponding to various specifications. The result is a significant reduction in the weight of the structure.

Chemical composition of Q390C steel plate: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.7, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.10, Al ≤ 0.015. The mechanical properties of Q390C steel plate are: yield strength ≥ 390 MPa, tensile strength 470-620 MPa, elongation after fracture ≥ 18%, impact energy 34J. S690QL1 1.8988 high strength steel plate, Q390C steel plate is used for bridges, vehicles, ships, workshops and other large structural parts, high and medium pressure Petrochemical vessels, boiler tubes, pipes, superheaters, pressure vessels, heavy machinery, etc. application.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
