S690QL equivalent carbon steel hr plates 2020.12.17

Characteristics and application scope of S690QL equivalent, 12Cr1MoV alloy plate:12Cr1MoV alloy plate is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power station boiler. At 580 ℃, it still has high thermal strength, oxidation resistance and durable plasticity. The production process is simple, the welding performance is good, but it is sensitive to normalizing cooling speed. Pearlite spheroidization will be produced after long-term use at 580 ℃.

The company adheres to the people-oriented concept and takes "learning, sharing, gratitude, integrity, respect and responsibility" as the enterprise values. Advanced equipment, scientific standardized management, strict quality assurance system and high-quality team are the core competitiveness of the company. The company will continue to provide customers with S690QL equivalent high-quality, timely and perfect steel products and services under the guidance of the mission of "striving for perfection to meet customer needs".

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched S690QL equivalent increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of S690QL equivalent during tempering, while tempering determines the performance and life of the workpiece.

Vanadium is a weak deoxidizer. Adding vanadium into S690QL equivalent steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel S690QL equivalent 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. Our after-sales service team will contact you if you have any question.
