Technical key points of 09CuPCrNi-B grade steel production

How much is the price of 09CUPCRNI-B grade steel, medium and heavy plate? First of all, there are many kinds of medium and heavy plate specifications, and the prices of different specifications are also different. Secondly, there are many kinds of medium and heavy steel plate materials. Different materials / steel grades have different uses, and the price will also change. Thirdly, we should also look at the manufacturers of steel products and pay attention to the steel grades of different manufacturers, so as to avoid buying poor quality medium and heavy steel plates.

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of 09CUPCRNI-B grade steel steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main 09CUPCRNI-B grade steel production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, 09CUPCRNI-B grade steel.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel 09CUPCRNI-B grade steel 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.
