What is 09CuPCrNi-B equivalent grades price today

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 equivalent grades. 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.

When the 09CUPCRNI-B equivalent grades, wear-resistant steel plate is produced, relevant heat treatment must be carried out, and then forging and processing are carried out after preheating. When the wear-resistant steel plate is heat treated, the temperature should be properly controlled. The heating temperature of the wear-resistant steel plate is 810-830 degrees, and the holding time depends on the furnace loading method. Tempering temperature: 320 degrees, sufficient time is necessary, oil cooling after tempering to reduce temper brittleness.

09CUPCRNI-B equivalent grades annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of 09CUPCRNI-B equivalent grades annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. 09CUPCRNI-B equivalent grades annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
