65Mn spring steel, also known as 65 manganese, is a spring steel material that complies with the GB/T 1222-2007 standard.
Composite steel is a composite material made by combining two or more different types of steel through methods such as extrusion, explosive welding, and rail manufacturing. Different layers have different functions.
50 steel is a medium-carbon high-strength carbon structural steel, corresponding to Japanese grades S50C/S53C and German grades 1.1213/CF53.
45 # steel is a high-quality carbon steel with a carbon content of 0.42% -0.50%, as well as alloy elements such as manganese (0.50% -0.80%) and silicon (0.17% -0.37%), while controlling the content of impurities such as chromium, nickel, phosphorus, and sulfur.
40 # steel has high strength and good machinability, moderate cold deformation plasticity, poor weldability, and can be welded after quenching and tempering.
Alloy steel is a steel material made by adding a small amount of alloying elements to carbon steel to enhance its mechanical properties and corrosion resistance.
Alloy steel is a steel material made by adding a small amount of alloying elements to carbon steel to enhance its mechanical properties and corrosion resistance.
Alloy steel is a steel material made by adding a small amount of alloying elements to carbon steel to enhance its mechanical properties and corrosion resistance.
T10 steel is a type of carbon tool steel with a carbon mass fraction of 0.95% to 1.04%. It is supplied in annealed state and has a hardness of ≤ 197HBW.
T9 is a high carbon tool steel, belonging to ordinary manganese non alloy steel with a carbon content of 0.90%, corresponding to international standards including Japanese JIS SK4, American AISI/SAE W1A-8 1/2, etc.
T8 steel is a type of eutectoid carbon tool steel with high hardness and wear resistance after quenching and tempering, but it has characteristics such as low thermal hardness, poor hardenability, and easy deformation due to overheating during processing.
This material has moderate hardness (up to 48-54HRC after quenching) and high toughness, but low thermal hardness and poor hardenability.
Due to the lower arc voltage characteristics of argon gas, which is particularly beneficial for manual arc welding of thin plates and wires, argon gas is chosen as the shielding gas.
Delivery status: Hot rolled steel is delivered in a heat-treated or non heat-treated state, while cold drawn steel is delivered in a heat-treated state.
Due to the tendency of 65Mn steel to overheat, the welding heat affected zone has a significant impact on the mechanical properties of the joint.
It has a higher hardness than SUS420J2 after quenching and is used for cutting tools, nozzles, valve seats, valves, etc.
