hot rolled 09CuPCrNi-B steel channel

A633GrD steel plate is suitable for normalized high-strength low-alloy structural steel plate for tower connection or source bolt connection structure. A633GrD steel plate should be normalized: heat the steel plate to a suitable temperature that can produce austenite structure but does not exceed 1700F [925℃], and keep it at this temperature for a period of time, so that the entire 09CUPCRNI-B steel plate can be uniformly heated, and then left in the air Cool with medium.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, 09CUPCRNI-B steel based on a high starting point and high technology, the company has vigorously developed various steel products 09CUPCRNI-B steel and deep-processed parts, steel structures, precision castings, seamless pipes.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized 09CUPCRNI-B steel are higher than that of annealed 09CUPCRNI-B steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of 09CUPCRNI-B steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.

The basic principle of 09CUPCRNI-B steel, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

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.
