Effect of microalloying element crystallization on properties of 09CuPTiRE-B steel grade

The company supplies more than 2,000 tons of pressure vessel steel materials to the Nigerian customer for the construction of atmospheric pressure tower in the refinery. This batch of 09CuPTiRE-B steel grade pressure vessel steel materials are tailored according to customer requirements, and the composition and process are newly designed. The performance of the pressure vessel steel materials meets the requirements of properties such as resistance to tempering embrittlement and hydrogen corrosion, and 09CuPTiRE-B steel grade special properties such as good formability, weldability and adaptability to welding process.

BBN employees work hard and work hard in their work. In life, colleagues care about each other, like a family, and accompany each other at important moments in life. BBN Steel organizes employees to carry out tourism activities every year, so that families can be exposed to nature and relax physically and mentally. The good combination of working and rest can achieve the goal of hard work and happy life.

17MN4 steel plate, 09CuPTiRE-B steel grade, DIN 17135 17MN4 steel plate is a kind of material for boiler and pressure vessel steel. DIN 17135 17MN4 steel plate is characterized by a minimum yield strength of 220 - 295 MPa and by good weldability, so 17MN4 steel is mainly used for manufacturing boilers, pressure vessels and pipes transporting hot liquids.

Chemical elements of 42SiMn steel: C: 0.39-0.45, Si: 1.10-1.40, Mn: 1.10-1.40. Mechanical properties of 42SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 40; impact energy: 47J. 42SiMn steel belongs to alloy quenched and tempered steel with good properties, high strength, wear resistance and hardenability. Under certain conditions, the strength, wear resistance and hot working performance of 42SiMn steel are better than 40Cr steel, 09CuPTiRE-B steel grade, and can be used instead of 40CrNi steel.

In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe 09CuPTiRE-B steel grade for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.

Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to 09CuPTiRE-B steel grade customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.
