35crmo Alloy Steel Plate Weldability
Calculated according to the carbon equivalent formula recommended by the International Welding Society (IIW) Ceq=C+1/6Mn+1/5(Cr+Mo+V)+1/15(Ni+Cu)(%) (1) When Ceq<0.40 When %, the hard tendency of steel is not obvious, the weldability is excellent, it is not necessary to preheat during welding, and 35crmo steel can be directly welded; (2) When Ceq=0.40~0.60%, the hard tendency of steel is gradually obvious, and the weldability is still good. Yes, it is necessary to take appropriate preheating before welding, slow cooling after welding and other process measures to control the welding line energy; (3) when Ceq>0.60%, the steel has a strong hard tendency and poor weldability. For steel grades that are difficult to weld, high preheating temperatures and strict process measures must be taken to select suitable welding materials. It was calculated that the carbon equivalent value of the 35CrMo steel was Ceq=0.72%. It can be seen that the weldability of the material is poor, the hard tendency is strong during welding, and the hot cracking and cold cracking tendency of the heat affected zone is large. Especially in the quenching and tempering state, the cold cracking tendency of the heat-affected zone will be very prominent. Therefore, based on the selection of suitable welding materials and reasonable welding methods, high pre-heating temperature before welding and strict technical measures should be adopted. The purpose of achieving product soldering can be achieved by controlling the proper interlayer temperature.
35crmo Alloy Steel Sheet Characteristics
35CrMo alloy structural steel has high static strength, impact toughness and high fatigue limit. The hardenability is higher than 40Cr and high at high temperature.
Creep strength and long-lasting strength, long-term working temperature can reach 500 °C; moderate plasticity in cold deformation, poor weldability. Low temperature to -110 degrees Celsius, high static strength, impact toughness and high fatigue strength, good hardenability, no tendency to overheat, small quenching deformation, good plasticity in cold deformation, medium cutting, but The first type of temper brittleness, weldability is not numbered, preheating to 150~400 degrees Celsius before welding, post-weld heat treatment to eliminate stress, generally used after quenching and tempering treatment, can also be quenched or quenched at high intermediate frequency surface and low Use after medium temperature tempering.
35crmo Alloy Steel Plate Application
35crmo alloy plates are mainly used to manufacture important parts in various machines subjected to impact, bending and high load, such as rolling mill herringbone gears, crankshafts, hammers, connecting rods, fasteners, turbine engine spindles, axles, engine transmission parts, Large motor shafts, perforators in petroleum machinery, boiler bolts with operating temperatures below 400 degrees Celsius, nuts below 510 degrees Celsius, high pressure seamless thick walled tubes in chemical machinery (temperature 450-500 degrees Celsius, non-corrosive medium) ), etc., can also be used to manufacture high-load transmission shafts, turbine engine rotors, large-section gears, support shafts (less than 500 mm in diameter), etc., instead of 40CrNi. Process equipment materials, pipes, welding consumables, etc.
35crmo steel is also suitable for the important structural component for working under high loads, such as transmission parts for vehicles and engines; rotors for main shafts, main shafts, heavy-duty transmission shafts, large-section parts
