The 09CuPCrNi-B steel equivalent yield strength from BBN

Q265GNH coil chemical composition: C: 0.17～0.24, Si: 0.17～0.37, Mn: 0.40～0.70, S: ≤0.035, P: ≤0.035, Cr: 0.80～1.10, Ni: 0.030, Cu: ≤0.030, Mo: 0.15 ~0.25 09CUPCRNI-B steel equivalent mechanical properties: Tensile strength σb (MPa): ≥885(90) Yield strength σs (MPa): ≥685(70) Elongation δ5 (%): ≥12 Reduction of area ψ (%): ≥50 Impact energy Akv (J): ≥78

BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December. Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.

Vanadium is a weak deoxidizer. Adding vanadium into 09CUPCRNI-B steel equivalent 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.

Special-shaped seamless pipe is the general term of seamless pipe with other cross-section shapes except circular pipe. According to the different shapes and sizes of steel pipe sections, it can be divided into equal wall thickness special-shaped seamless pipe (code D), unequal wall thickness special-shaped seamless pipe (code BD), variable diameter special-shaped seamless pipe (code BJ). 09CUPCRNI-B steel equivalent. Special seamless pipe is widely used in all kinds of structural parts, tools and mechanical parts. Compared with the round pipe, the special-shaped pipe has larger inertia moment and section modulus, larger bending and torsion resistance, which can greatly reduce the structure weight and save steel.
