12Cr1MoV alloy plate is widely used in superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power plant boiler. At 580 ℃, 12Cr1MoV alloy plate still has high thermal strength, oxidation resistance and high endurance plasticity. The production process of q355gnh hull structure steel and 12Cr1MoV alloy plate is simple and the welding performance is good, but it is sensitive to the normalizing cooling rate. Pearlite spheroidization will occur after long-term use of 12Cr1MoV alloy plate at 580 ℃.

The alloy steel seamless pipe is a kind of product developed on the basis of traditional seamless steel pipe. Some characteristics of the q355gnh hull structure steel, 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.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld q355gnh hull structure steel steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for q355gnh hull structure steel manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).

q355gnh hull structure steel, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
