Alloy plate is a kind of steel plate with high thermal strength and oxidation resistance at high temperature, which has certain hydrogen corrosion resistance. Alloy plate is a new type of steel plate formed by adding other elements on the basis of steel plate material, which is to solve the problems existing in ordinary carbon steel plate. Alloy plate can be divided into bridge steel plate, boiler steel plate, shipbuilding steel plate, armored steel plate, automobile steel plate, roof steel plate, structural steel plate, silicon steel sheet, spring steel plate, S690QL heat treatment, etc.

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 heat treatment, clad steel plate has better requirements for production technology and are more expensive.

Steel plate S690QL heat treatment cutting, according to different classification standards, there are different specific types. If it is divided by cutting temperature, it can be divided into cold cutting and hot cutting. One of the cold cutting, there are water jet cutting and abrasive cutting and so on, thermal cutting is flame cutting, plasma cutting and laser cutting. In addition, we also need to know that the high-grade thick S690QL heat treatment steel plate can be cut by flame, and its cutting is as simple as that of ordinary low-carbon and low-alloy steel, but we need to pay attention to it.

Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. S690QL heat treatment, Q420C steel has good mechanical properties and weldability, good cold and hot workability.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel S690QL heat treatment plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust.
