What is the difference between ST37-2 material and 09CuPCrNi-B steel elongation

ST52-3 low alloy steel is equivalent to domestic brand Q345. St52-3 new material number: 1.0570, old material number: 1.0841. St52-3 takes its tensile strength and yield point as its main characteristics. 09CUPCRNI-B steel elongation products are generally used in the manufacture of various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment used in mining and various engineering constructions And other structural parts.

Weather-resistant steel plate refers to steel plate that is resistant to weathering and corrosion. 09CUPCRNI-B steel elongation, Weather-resistant steel plate can adapt well to the environment and is widely used in construction, bridges, roads and other fields with outstanding performance characteristics. One of the outstanding advantages of weather-resistant steel plate is its ability to adapt to a variety of different environments, whether it is in severe cold areas or tropical areas. The weather-resistant steel plate can better maintain its characteristics in various complex environment.

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 elongation are higher than that of annealed 09CUPCRNI-B steel elongation, but the elimination of internal stress is not as good as annealing. The normalizing operation of 09CUPCRNI-B steel elongation is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s 09CUPCRNI-B steel elongation domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.

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.
