What is the distinguishing feature of different material of stainless steel spring

Stainless steel is increasingly used to manufacture the spring. This kind of raw material is durable, even in the bad environment is not easy to environmental pollution or etching. In addition, some stainless steel aluminum alloy has better heat resistance. Heavy YingDeHua ( PH值) , austenitic austenitic stainless steel, dual phase and ferrite is a few kinds of stainless steel. In this kind of type, austenitic stainless steel and heavy YingDeHua ( PH值) Used to manufacture the spring. Ever stronger springs for various industrial production industry is famous customers produce standard and custom-made stainless steel spring spring factory. Made of 304 stainless steel spring: 304 stainless steel spring is also the Chinese great demand of stainless steel spring, 304 is a stainless steel, chromium nickel into mirror glass, smooth surface and frosted three kinds. According to the name you can look out the mirror glass is high brightness, like a mirror, very suitable for medical mechanical spring and its art spring to application, due to the stainless steel mirror glass is not easy to stick vegetable fat, easy to remove. Contrast smooth stainless steel mirror glass stainless steel spring, surface gloss slightly almost, if want to as medical mechanical spring, must be carried out after spring forming grinding polishing. Ultimately is the great demand of grind arenaceous stainless steel, such as stainless steel due to the low price, relativity before both, physical properties and antirust processing capacity are all the same, therefore, common to all sorts of spring must be antirust processing. Temperature for - strongly recommended applications 40°~120°( Not recommended for more than 120 °, or physical properties will reduce) Made of 302 stainless steel spring: 302 stainless steel spring actually foreign demand is very big, is greater than 304. From the physical properties, the actual effect is better than 304 stainless steel spring, but the antirust processing capacity due to the element composition, slightly less than 304. But on the whole, is not much difference, many conditions, 302 and 304 spring if made of elastic precision is not very high, can be used in addition to an alternative. Temperature for - strongly recommended applications 40°~120°( Not recommended for more than 120 °, or physical properties will reduce) Temperature for - strongly recommended applications 40°~120°( Not recommended for more than 120 °, or physical properties will reduce) 。 301 stainless steel spring: 301 stainless steel spring is equal to the harp in stainless steel stainless steel wire. Elasticity and fatigue sex is far ahead of the two, especially when the basic spring such as 302 ~ 304 stainless steel material can not meet the requirement of the strength of the spring under the condition of application. Temperature for - strongly recommended applications 40°~120°( Not recommended for more than 120 °, or physical properties will reduce) 316 stainless steel spring: 316 stainless steel spring compared with other types of stainless steel, more appropriate in such as the surface of the application, better than other types of stainless steel corrosion resistance. Also have low magnetic characteristics. Temperature for - strongly recommended applications 40°~120°( Not recommended for more than 120 °, or physical properties will reduce) 631 stainless steel spring: 631 stainless steel spring is a half the austenitic stainless steel sink YingDeHua stainless steel, the application of mechanical equipment and medicine industry is more, have strong ability of corrosion resistance and toughness, have higher fatigue characteristics. Especially the heat-resisting ability, 631 spring is different from the other stainless steel, can be in - Among 40 ~ 380 ° application, many conditions be employed as a high temperature resistant spring steel. 13 b250 non-magnetic stainless steel spring: 13 b250 non-magnetic stainless steel spring have very weak magnetic, suitable application in electric power engineering, the dashboard application. No magnetic spring and is not completely without magnetic. Is there will be a belt magnetic steel. If in the end, the stainless steel will be attracted to a magnet is not distinguish is non-magnetic stainless steel according to, be a magnet suck up the consciousness of the stainless steel is stainless steel 201 is not correct. Friction caused when cold drawn stainless steel wire, must be attach more or less with magnetic, the component larger components in stainless steel is iron, iron will be attracted to a magnet. In addition a kind of method is made of stainless steel spring according to above 800 ° of high temperature quenching, remove his belt, the other will produce changes in the organizational structure of stainless steel, and not the characteristics of raw materials on their own, therefore, if there is no magnetic spring, be sure to choose 13 b250 stainless steel spring.
