What is the difference between ST37-2 material and 20MnB5 boric steel

According to the data released by the Japan iron and Steel Union (JISF), the export volume of Japanese steel in the second quarter of 2020 20MnB5 boric steel is about 4.959 million tons, a year-on-year decrease of 14.2%; the export volume in the first half of 2020 is about 11.07 million tons, with a year-on-year growth of 1.8%. It has been revealed that the year-on-year increase in export volume does not mean that Japan's export 20MnB5 boric steel situation of Pugang is better in the first half of the year, but only because the base number of the same period last year is too low.

The company has a group of mature steel plate production and processing line construction and production management experience. In addition, the company has professional and technical personnel. BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service. The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. At the same time, it also adheres to international standards and adheres to the international line.

Compared with 20MnB5 boric steel, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while 20MnB5 boric steel is not.

Our company is located in the Central Plains, Zhengzhou City, convenient transportation. There is the largest Xinzheng airport, welcome customers from all over the world to visit our company. Our factories are all located near the port. The logistics is very convenient, which can save the delivery time.

Peritectic reaction often occurs in the process of cooling and solidification of wear-resistant steel plate, 20MnB5 boric steel, and accompanied by this reaction, there will be greater volume change and linear shrinkage, which is mainly due to the hot cracking of continuous casting slab in the casting process. In the mold, the heat load transmitted from the billet is too much or uneven around the meniscus of molten steel, resulting in uneven heating, which is more likely to produce longitudinal cracks.

We are experienced shipbuilding and marine grade steel materials supplier and exporter with more than 20 years experience. For any question about the 20MnB5 boric steel shipbuilding steel materials, such as shipbuilding steel price, ABS EH36 steel specification, Lloyds grade A steel properties, AH36 steel mechanical properties, AH32 steel price, DH32 steel dimensions, difference between EH36 and DH 36 etc., please feel free to consult us.

Both parties shall confirm the 20MnB5 boric steel material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the 20MnB5 boric steel steel plant.
