35CrMo ally pipe application

35crmo steel is one of the alloy material, it iswidely used to manufacture important parts of various machines that bear the impact, twist and high load. 35CrMo's Ceq=0.72%. It is It can be seen that the weldability of this material is poor, the hardening tendency of the material is larger, the thermal cracking and cold cracking tendency of the heat affected zone will be larger, especially in the quenched and tempered state, the cold cracking tendency of the heat is easily affected. Therefore, it should be in the selection of suitable welding materials, reasonable welding method on the basis of a higher preheating temperature before welding, strict process measures and control the appropriate layer temperature conditions, in order to achieve the product welding.
35CrMo alloy structural steel has a high static strength, impact toughness and high fatigue limit, hardenability than 40Cr high, high temperature creep strength and lasting strength, long-term working temperature up to 500 ℃; the Cold deformation plastic medium and welding performance is poor.
Low temperature to -110 ℃, and has a high static strength, impact toughness and high fatigue strength, good hardenability, no overheating tendency, quenching deformation, cold deformation plastic can still, medium processing, The first type of temper brittleness, welding is not good, before welding to be preheated to 150-400 ℃, after welding heat treatment to eliminate stress, usually in the quenching and tempering treatment can also be used in high frequency surface quenching or quenching and low.Henan Bebon International Co.,Ltd Could produce 35CrMo material under GB/T11251-2009, and the delivery condition is Normalizing, tempering and quenching.
35CrMo steel is Used in the manufacture the important parts of various machines, such as rolling mill, crankshaft, hammer rod, connecting rod, turbine engine spindle, axle, engine transmission parts, large motor shafts, Petroleum machinery in the perforator, etc . It Could also instead of 40CrNi used in the manufacture of high-load drive shaft, turbine engine rotor, etc .; process equipment materials, pipe, welding and so on.
35CrMo alloy steel is also used as important structural parts for high load operation, such as vehicle and engine transmission parts; Turbine generator rotor, spindle, heavy load drive shaft, large cross-section parts.
