What is the application scope of S690QL hardness

In terms of service, our service is a "one-stop" way of working. We have our own S690QL hardness processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as S690QL hardness cutting, welding, drilling, galvanizing, etc., at the lowest cost.

S690QL hardness, Weathering steel plate is a kind of commonly used building materials with both functionality and aesthetics. Therefore, weathering steel has been widely used in the field of processing and decoration in the construction industry, and has been favored by many architects and landscape designers. Weathering steel has strong corrosion resistance and wear resistance. It not only has been applied in construction industry, but also have a wide range of applications in other fields.

The clad steel plate is based on carbon structural steel, which is sprayed with stainless acid resistant and heat-resistant steel on the surface. The clad steel plate is widely used to make acid and alkali resistant container. Advantages of clad steel plate: The appearance of the clad steel plate is very smooth, the quality is very good, and it will not rust. Disadvantages of clad steel plate: the S690QL hardness, clad steel plate has better requirements for production technology and are more expensive.

Phosphorus is a very harmful element in S690QL hardness steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of S690QL hardness steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

The difference of chemical composition between S690QL hardness, Q420D steel and Q460D steel:
Chemical composition of Q420D steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20, Al ≥ 0.015. Chemical composition of Q460D steel: C ≤ 0.20, Si ≤ 0.60, Mn ≤ 1.80, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.55, N ≤ 0.015, Mo ≤ 0.20, B ≤ 0.004, Al ≥ 0.015.
The difference of mechanical properties between S690QL hardness, Q420D steel and Q460D steel:
The mechanical properties of Q420D steel: yield strength ≥ 420 MPa, tensile strength 500-680 MPa. The mechanical properties of Q460D steel: yield strength ≥ 460 MPa, tensile strength 500-720 MPa.
