The maximum depth shall not exceed the depth specified in the table below.Degree of defects. VD grade, TD grade steel wire shall not have full decarburization, but allow not more than d1.0% of the semi-decarburization.Maximum Depth Allowable for Surface Defects     Heat treatmentSpring, the spring should be tempered between 380 ℃ ~ 420 ℃ treatment to reduce surface stress, shot blasting should be 250 ℃ hot pressure or eliminate the stress treatment.delivery statusThe wire is delivered in coil formOil quenched - Tempered spring steel wireSuitable for general purpose springs, brake brakes springs, middle and high grade automobile clutch springs, shock absorber coil springs, belt tensioner springs and steel wire for manufacturing engine valve springs.Mechanical propertiesStatic level, in the fatigue class mechanical properties table (the same disk strength of not more than 50MPa)High fatigue level mechanical properties table (with the disc strength is not greater than 40MPa) The grades of spring steel is introduced1、65#、70#Can get very high strength, hardness, yield ratio, but the hardenability of small, heat resistance is not good, bear the load and fatigue load capacity is low is widely used, but more for low working temperature of small springs or less important big spring.Such as automobile, tractors, railway vehicles and the general use of the machinery spring2、65MnComposition is simple, the hardenability and mechanical properties, and process performance than carbon steel, low price, large amount of.Applicable to the manufacture of a variety of small cross section flat spring, spring, spring, or making ring spring, damper and a clutch spring, brake spring.3、60Si2MnAHigh strength, good elasticity; resistance to tempering stability; a main spring steel, uses a very wide.Suitable for manufacturing all kinds of springs, such as automobiles, locomotives, tractors, spring spiral spring, cylinder safety valve spring and some under high stress work important spring, serious abrasion of the spring.4、50CrVABecause of containing a small amount of vanadium can improve flexibility, strength, yield ratio and sag resistance, grain refinement, reducing decarbonization tendency.Carbon content are smaller, plasticity, toughness good than other spring steel.Hardenability high, fatigue or applicable to various important helical spring, in particular is suitable to high job stress amplitude, fatigue properties require strict spring, such as valve, spring, spring nozzle cylinder ring, a safety valve spring5、55SiCrA   SAE9254  SAE9254VHigh tensile strength and yield strength, and good processing performance, can withstand higher stress load, mainly used for turbine steam seal spring, engine valve spring, valve spring, a regulating spring, a condenser support springHeat treatmentSpring, spring should be at 380 ℃ ~420 ℃ tempering treatment,In order to reduce the surface stress, shot blasting should be at 250 ℃ heatPressure or stress relieving treatmentDelivery conditionWire coil in order to deliveryFAQ:Q: Are you trading company or manufacturer?A: We are factory.welcome?
