09CuPCrNi-B grade steel carbon steel plate grade

The company mainly supplymild 09CUPCRNI-B grade steel steel plate, alloy steel plate, boiler plate, corten steel plates for railway, marine, automotive, home appliances, shipbuilding, construction, machinery manufacturing and oil tank projects. While accelerating the development of the main steel industry, the company adheres to a diversified development strategy and actively develops the other industry like household products, face mask machine, precision casting producing, steel structures, and heavy plates processing service.

The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, 09CUPCRNI-B grade steel professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better 09CUPCRNI-B grade steel tomorrow!

Try to use 09CUPCRNI-B grade steel high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the 09CUPCRNI-B grade steel temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

The final heat treatment of quenched and tempered alloy steel, 09CUPCRNI-B grade steel is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.

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.
