Technical requirements for S690QL 1.8928 steel sheet

30CrMnTi steel has higher strength and hardenability than 20CrMnTi steel, but its impact toughness is slightly lower. Mainly used as carburizing steel, it can be quenched directly after carburizing, with high bending strength and good wear resistance. It can be used after quenching, low temperature tempering or quenching and tempering, with medium machinability. 30CrMnTi steel can be used in the manufacture of heavy-duty carburized parts with large cross-sections and gears, gear shafts, worms, etc. with large forces in the tractor industry.

Cold rolled coil products S690QL 1.8928 steel sheet have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products S690QL 1.8928 steel sheet is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils S690QL 1.8928 steel sheet with different surface roughness can be produced (glossy surface or matte surface, etc.).

"Mirror" refers to the surface state of S690QL 1.8928 steel sheet stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.
