A514 grade Q steel material chemical composition

At the same time, the company operates a variety of products of related iron and A514 grade Q steel material 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 A514 grade Q steel material 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.

Our company's logistics breaks through the perspective that the center of transportation service is ability, and emphasizes that the purpose of transportation service is customer first. Customer demand determines the content and mode of transportation service, while production is often small batch, diversified and consumer demand tends to be diversified. In the case of personalization, our logistics service also provides personalized service projects.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the A514 grade Q steel material steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of A514 grade Q steel material seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our A514 grade Q steel material office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase A514 grade Q steel material 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.

A514 grade Q steel material, ASTM A131 shipbuilding steel has different grade levels. The ordinary strength shipbuilding steel grades are grade A/B/D/E. Their min. yield strength is 235 Mpa, and tensile strength is 400-520 Mpa. The higher strength shipbuilding steel grades are grade AH32/DH32/EH32/FH32, AH36/DH36/EH36/FH36 AH40/DH40/EH40/FH40. The min. yield strength of AH32/DH32/EH32/FH32 steel is 315 Mpa, and tensile strength is 440-590 Mpa. The min. yield strength of AH36/DH36/EH36/FH36 steel is 355 Mpa, and tensile strength is 490-620 Mpa. The min. yield strength of AH40/DH40/EH40/FH40 steel is 390 Mpa, and tensile strength is 510-650 Mpa.
