How to quickly judge whether the price of hot rolled steel plate S690QL, weathering steel plate is reasonable? What are the factors influencing the price quotation of hot rolled steel plate S690QL, weathering steel plate? First of all, the material composition of weathering steel plate is different, and the corresponding performance and price are also different. Therefore, when we talk about the price of hot rolled steel plate S690QL, weathering steel plate, we should first make clear of the material composition. Secondly, the specification especially the thickness of the hot rolled steel plate S690QL, weathering steel plate will affect the quotation. Generally, the thicker the weathering steel plate, the higher the price.

The alloy steel seamless pipe is a kind of product developed on the basis of traditional seamless steel pipe. Some characteristics of the hot rolled steel plate S690QL, alloy steel seamless pipe are also great progress and optimization based on the traditional seamless steel pipe products. Alloy steel seamless pipe is a kind of high performance seamless pipe. In industrial production, seamless pipe is usually used in pipeline engineering which needs to bear greater pressure.

The hot rolling method is to heat the hot rolled steel plate S690QL steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of hot rolled steel plate S690QL rolling process is usually called semi-finished product production, also called blank production.

Heat treatment specification and microstructure of hot rolled steel plate S690QL, 12Cr1MoV alloy plate:Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling. Microstructure: bainite + ferrite.Mechanical properties of 12Cr1MoV alloy plate:Tensile strength σb (MPa)：≥490(50); Yield strength σs (MPa)：≥245(25); Elongation δ5 (％)：≥22; area shrinkage ψ (%): ≥ 50; Impact energy Akv (J): ≥ 71; Impact toughness value αkv (J/cm2)：≥88(9).

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
