20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.
Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled KF40 ocean engineering steel plate products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the KF40 ocean engineering steel plate rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
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. KF40 ocean engineering steel plate, 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.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
