How to improve toughness of 09CuPCrNi-A machinability

In recent years, in line with the development trend of iron and 09CuPCrNi-A machinability steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which 09CuPCrNi-A machinability are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

ASTM A36 and JIS G3192 steel angle 09CuPCrNi-A machinability is one of the most widely used carbon steel section in the construction industry and project. It is a low-cost material and shows the required strength property compared with other steels. It is popular also for its good weld performance, formable, and easy 09CuPCrNi-A machinability machining. Galvanizing and other treatment increases its resistance to corrosive environment.

Our company produces ordinary carbon steel 09CuPCrNi-A machinability with high strength and good plasticity and toughness. Due to the effect of alloy elements, its strength is 25% - 50% higher than that of ordinary carbon steel, its elongation is 15% - 23%, and its impact toughness at room temperature is higher than 60j / cm 2. We have a 09CuPCrNi-A machinability production line specializing in the production of ordinary carbon steel plate, and strictly control its quality.

After extrusion, the 09CuPCrNi-A machinability tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

Chemical composition of 65Mn steel: C 0.62-0.70, Si 0.17-0.37, Mn 0.90-1.20, Cr ≤ 0.25, Ni ≤ 0.30, Cu ≤ 0.25. 65Mn steel mechanical properties: tensile strength: ≥735 Mpa, yield strength: ≥430 Mpa, elongation after fracture: ≥9%, reduction of area: 30%, impact absorbed energy: no impact. 09CuPCrNi-A machinability, 65Mn steel has high strength, high hardenability, less decarburization tendency, overheat sensitivity, easy to produce quenching cracks and temper brittleness. 65Mn steel is used for making various flat and round springs, leaf springs, spring rings, valve springs, steel wire cold coil springs, clutch springs of light trucks and cars.
