Spring characteristics and applications | ||
Spring Type | Features | Application |
V-Type | Allowable deformation is large, deformation elasticity is small, elasticity is stable, and compensation for dimensional deviation is large | Reciprocating motion is suitable for medium pressure environment and can adapt to small size deviation |
O-Type | Small allowable deformation, large deformation elasticity, and small ability to compensate for dimensional deviation | Each coil of the spring is evenly stressed and is suitable for medium and high pressure environments and low temperature locations |
S-Type | The allowable deformation is large, the sealing force and friction force are constant within the deformation range, and the ability to compensate for dimensional deviation is large | Suitable for low pressure environment |
Spring material | ||
Material | Basic performance | application |
301 | Resistant to air and some chemical media corrosion, excellent fatigue resistance, but not resistant to chloride ion environment | Air, oil, grease, water, steam, food, medicine, etc. |
304 | Good corrosion resistance, heat resistance, low temperature strength and mechanical properties | Air, oil, grease, water, steam, food, medicine, etc. |
316L | Good corrosion resistance, mechanical strength slightly lower than 304. | Acids, caustics, acetic acid, agrochemicals, pickling and acid regeneration plants |
718 | Low temperature stable chemical properties, high temperature oxidation resistance and high tensile, fatigue and fracture strength | Low temperature, high temperature, acid, nuclear engineering, liquid, fuel rocket, etc. |
C276 | Excellent resistance to inorganic acid corrosion, such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid and mixed acid of sulfuric acid and hydrochloric acid, etc. | Specially used in highly corrosive environments, such as sea water, concentrated sulfuric acid, concentrated nitric acid, etc. |
