Use stainless steel spring wire

by:Yongqiang     2020-09-08
Use stainless steel spring line all kinds of stainless steel materials because of its material content is different and has different characteristics and corrosion resistance also vary. The following several kinds of commonly used material for a simple explanation:


304 is a kind of common stainless steel, it is widely used to make a good comprehensive performance ( Corrosion resistance and formability) Equipment and parts.


301 stainless steel during deformation presents obvious work hardening phenomenon, a high intensity was used for various occasions.


302 stainless steel is essentially higher variations of 304 stainless steel, the carbon content by cold rolling can make its higher strength.


302 b is a kind of high silicon content in stainless steel, it has the high oxidation resistance.





se is 303 and 303 respectively containing sulfur and selenium free cutting stainless steel, used for main requirements free cutting and high surface finish.


303 se stainless steel is also used to make part of the need of hot upsetting, because in such conditions, the stainless steel has good hot workability.


304 l is low carbon content variations of 304 stainless steel, welding is applied to the occasion. Low carbon content is made in the heat affected zone near the weld in the precipitation of carbide to a minimum, and may result in precipitation of carbide stainless steel intergranular corrosion in some environments ( Welding erosion) 。


304 n is a kind of stainless steel containing nitrogen, and nitrogen is in order to improve the strength of the steel.





316( 18 cr - 12Ni- 2. 5Mo) Material: because of the added Mo, so its corrosion resistance, resistance to atmospheric corrosion resistance and high temperature strength particularly well, and can be used in critical conditions. Excellent work hardening, No magnetic) 。 Purpose: paper, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, rope, CD rod, bolts and nuts.


the hardness of spring line has the following several kinds: the soft hard | | a quarter and a half hard hard hard hard | | 3/4 full |. Specification: Ф 0. 08mm~Ф12. 6mm。


the purpose of the stainless steel spring wire, stainless steel spring wire of different hardness due to their different purposes, generally used as life tiny elastic products, also have for automotive spring, compression spring, widely used in the normal life.


stainless steel spring wire intraspecific: see in appearance, spring line generally divided into the mist side spring line and the surface of bright spring line, fog face the spring wire hardness lighter spring surface of high hardness, can be used for hanging fixture line, commonly used in cosmetic requirements on products in the high elasticity of demand is not high. In nature, spring wire is also divided into magnetic spring are non-magnetic spring line and line, non-magnetic spring line caused by excess Mn element spring line toughness is poorer, magnetic spring line are generally used in magnetic small item request is not high.
