40CrNiMoA steel is a Chinese alloy steel, has high strength, toughness and good hardenability, and has anti-overheating stability, but has high white point sensitivity, temper brittleness and poor weldability. Preheating is required before welding, and stress relief treatment is required after welding.
GB/T1591 Q460 contains three different steel grades as Q460C,Q460D and Q460E.Structural steel Q460D shall be done impacting test at low temperature minus 20 degree centigrade.Normalised heat treatment suggested to be done for low alloy steel plate Q460D in heavy thickness,Quenched and tempered is also adopt when end users demand.
T8, T10 and T12 are carbon tool steels. They are very hard. The Brinell hardness in annealed state is more than 300.Manual saw blade is T12 material, just quenching, hardness is greater.10 and 20 are low carbon, high quality structural steel, very soft, Brinell hardness is less than 155.Therefore, the fitter saw, laborious, the saw is very easy to wear.
CR12 round steel refers to a solid long steel with a circular cross section. The specifications are expressed in millimeters of diameter. For example, "50" means round steel with a diameter of 50 mm. Round steel is divided into three types: hot rolled, forged and cold drawn.
