Effect of grain size on yield strength ratio of 09CuPCrNi-B steel material

In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.

BBN company is one of the most important manufacturers of 09CUPCRNI-B steel material medium and heavy steel plates for shipbuilding in China. The general strength shipbuilding steel Grades A, B, D, E and higher-strength grade AH32, AH36, DH32, DH36, EH32, EH36 hull structural steel plates produced by heavy steel (specifications: 6-32mm) have been obtained by nine classification society approval certificates Like ABS, CCS, LR, DNV, GL, RINA, and KR.

Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter 09CUPCRNI-B steel material steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.
