Henry Spring is the largest spring manufacturing company maintain its leading position in the domestic spring industry, the initial production of watches and clocks spring, famous for the quality and stability, both in the spring production technology and equipment are the highest domestic.。

  The torsion springs (torsion spring) is one of the widely used spring. Henry spring production of various specifications torsion springs (torsion spring) is well-known superior quality and stable. Henry spring HENRY (standing standard) torsion springs (torsion spring) and custom torsion springs (torsion spring) solution

HENRYCompression spring（Compression spring）-Instrument metal strings and stainless steel standing size
Henry Spring Manufacture of a variety of standard standing(HENRY)Compression spring。The standard of our standingCompression springPrecision engineering to save time and economic costs for design engineers, cartographers, and maintenance departments with a spring. Reliable quality of these springs, the use of high efficiency, very suitable for general industrial use。

Material

	No. C at the beginning of the components used in the instrument metal strings: ASTM A228 or the AMS 5112. When the temperature over 121 degrees Celsius (250 degrees Fahrenheit) is not recommended to use the instrument metal strings Material of spring。
	No. C at the beginning of Stainless steel parts line: 302Stainless, steel, in line with the ASTM A313 or AMS 5688， Spring after the tempering treatment (only the physical and chemical properties). When the temperature is over 260 degrees Celsius (500 degrees Fahrenheit), and do not recommend the use made ??of Stainless steel spring。
	Instrument metal strings numbered beginning with D components: compliance with DIN 17223 or JIS G4314 SWP-NB Or AMS 5112, is not recommended to use the instrument metal strings Material of spring。
	Stainless steel line number to the beginning of D parts：301、302 or 304Stainless steel，Conform DIN 17224 or JIS G4314 SUS 302/304 or AMS 5688，Spring after tempering at Reason（Only physical and chemical properties）。When the temperature is over 260 degrees Celsius (500 degrees Fahrenheit), and do not recommend the use made ??of Stainless steel spring。
	Type 302 Stainless steel is slightly magnetic point. The on the surface of of the Stainless steel may Another point of the the the remnants of nickel. This is quite normal and does not affect the function of the part。
	The diameter of the metal wire is forming before the diameter。
	Unless specified Stainless steel instrument metal strings should be used under normal circumstances. Inquiry and order, use the letter "M" or the letter "S", respectively, Stainless steel instrument metal strings。
	If necessary, a certificate of competency can be provided free of charge.Can provide a chemical analysis certificate, see price book。

Compression spring（Compression spring）Carrying the load and the coefficient of elasticity
Instrument metal strings and Stainless steel wire Compression the spring table column lists their respective carrying the load and the elastic coefficient。 If you need a higher standard, please contact our engineering department。

	The end of the ground into a square. Free length L is for reference only. In length L1, the load P If Material is Stainless steel, then P is multiplied by a coefficient of -0.833。
	Load values ??are shown in the case the value of Material for the instrument metal strings。
	A fixture, you can generally use the occasion should not be the spring compressed to L1. Below (larger than the L1.。）
	If you want to determination of length other than other than L1. Load P, with the recommended amount of compression is multiplied by the R * [P = (L-Lx) x R]. If Material is Stainless steel, relative to the value of the coefficient R must be multiplied by 0.833, corrected。

Tolerance

Tolerance range of the instrument metal strings and Stainless steel standing Compression the spring

Load, P at L1 ± 10%
Coefficient of elasticity, R ± 10%
*Lx = Load under the required length。

Last channel Qiceng,
Instrument metal strings: oiled
Stainless steel Line：Smooth wire
We can provide special treatment to your needs。
