Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant bending or twisting.

Spring steel usually works under impacting and vibrating ,shaking and some other steady circumstances,so, spring steels usually have high yield strength,tensile strength and high elongation,high elasticity.
For spring steels used in high temperature situations,they are also required to have high temperature resistance,resistant of oxygenation corrosion,and low magnetism.
Spring steel is also commonly used in the manufacture of metal swords used for stage combat due to its resistance to snapping or shattering. Spring steel is one of the most popular materials used in the fabrication of lockpicks due to its pliability and resilience. Applications include piano wire, spring clamps, antennas, and springs.
Category of spring steels:
According to their chemical properties, spring steel can be divided into carbon spring steels and alloy spring steels.
Carbon spring steels have a content of element carbon(percentage in mass) from 0.62% to 0.90%,and according to the content of manganese,they can be divided in to general Mn content spring steels(percentage in mass)(0.50%~0.80%) , and high manganese spring steels(percentage in mass)(0.90~1.20%).
Alloy spring steels mains means base on the concept of carbon spring steel, to improve the mechanical property,harden-ability,and some other properties through adding in one or several other metal elements,so as to fulfill the demand of steels to make every kind of springs.For example,we have Si-Mn spring steels,Si-Cr spring steels,Cr-V spring steels,W-Cr-V spring steels,and based on these steel,in order to improve the property of some other aspects,Mu,V,and B elements are added in some other grades.
What is more, some grades from fine grained structural steels and carbon tool steels,stainless steels are chosen to be classified as Spring steel.
The main grades of Spring steel are:65,TYPE SC,TYPE DC,1065,SWRH67A,SWRH67B,C66D,70,SWRH72A,SWRH72B,C70D,85,DM,DH,SH ,1084,SWRH82A,SWRH82B,C86D,65Mn,65TA,1566,55Si2Mn,55C2T,55Si7,56SC7,55Si2MnB,55SiMnVB,60Si2Mn,60C2T/60C2A,60SiCr7,61SiCr7,59Si7 ,9260,G92600,SUP6/SUP7,251H60,60Si2MnA,60Si2CrA,60C2XA,685H57,60Si2CrVA,60C2XA,55CrMn,55Cr3,5155,G51550,H51550,SUP9/SUP9A,,60CrMnA,5160,G51600,H51600,SUP9A,,60CrMnMoA,60CrMo4,60CrMo33 4161,G41610,H41610,SUP13,705A60/705H60,,50CrVA,50TA50CrV4,50CrV4,51CrV4,6150,G61500,SUP10, 735A51/735H51,60CrMnBA,60CrB3,H51601,SUP11A,30W4Cr2VA ,30WCrV17.9,70Si2CrA,55CrSiA,67CrVA,FDCrV-B/TDCrV-B/VDCrV-B
