What is the chemical composition of RB hull structural rolled steel?

At the same time, the company operates a variety of products of related iron and RB hull structural rolled steel steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained RB hull structural rolled steel ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.

The quality of RB hull structural rolled steel shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of RB hull structural rolled steel buyer, such as packaging, delivery time, etc.. On the basis of the quality of RB hull structural rolled steel in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of RB hull structural rolled steel and certain performance limit of RB hull structural rolled steel, etc.

16MnDR steel plate is suitable for low temperature pressure vessels manufacturing. Grade 16Mn- indicates that the content of manganese (Mn) in the steel plate is relatively high, about 1% -1.6%, D- indicates low temperature, R- indicates pressure vessel. (Normally, when the content of a certain chemical element in steel is high, it needs to be marked in the material, for example, 1.6% manganese is written as 16Mn; certain elements such as Cr and Mo are higher, written as Cr1, Mo1, Such as 12Cr2Mo1R.) The normal delivery status is normalized delivery (Normalized).

Vanadium is a weak deoxidizer. Adding vanadium into RB hull structural rolled steel steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

Delivery status: 16MnDR steel plate is normalized or normalized and tempered. 6-60mm16MnDR-40℃ impact, 60-120mm16MnDR-30℃ impact.
Ultrasonic testing of 16MnDR steel plates: The RB hull structural rolled steel plates delivered in the normalized or normalized and tempered state with thickness greater than 20mm and the steel plates delivered in the quenched and tempered state with thickness greater than 16mm shall be ultrasonically tested one by one.
