Embodiment Construction

[0014] A precision internal diameter stainless steel seamless steel pipe for hydraulic and pneumatic cylinders is made of austenitic stainless steel, processed by metal rolling processes such as two-roll and three-roll cold rolling, and then solid-solution heat treatment. The invention is mainly used in hydraulic and pneumatic cylinders, automation equipment and the like. Due to the characteristics of austenitic stainless steel materials such as non-hardenability, corrosion resistance, weldability, non-magnetism and tough plasticity, the corrosion resistance and wear resistance of the product are enhanced, processing is convenient, and the product can adapt to harsh and harsh conditions. The working environment under special circumstances, the scope of use is further expanded.

[0015] The length of the steel pipe is usually 1m ~ 6m, such as the grade of 06Cr18Ni11Ti, 06Cr19Ni10, 06Cr17Ni12Mo 2 , 022Cr17Ni12Mo 2 Made of austenitic stainless steel. The roughness of the inner...

Abstract

The invention relates to a stainless steel seamless steel tube with a precise inner diameter for a hydraulic and pneumatic cylinder, which is mainly used for manufacturing and processing hydraulic and pneumatic elements or being directly processed into cylinder pipes. The stainless steel seamless steel tube with the precise inner diameter for the hydraulic and pneumatic cylinder is made of an austenite stainless steel material instead of a common carbon steel material, the inner surface roughness thereof completely adopts the precision of more than 0.8mum of a nominal value Ra, and the allowable precision deviation of the outer diameter size thereof is improved by one time than that of the steel pipe product made of the common carbon steel material. The stainless steel seamless steel tube with the precise inner diameter for the hydraulic and pneumatic cylinder enhances corrosion resistance and wear resistance of the product, enables the product to adapt to severe and special working environment, has the characteristics of good inner-surface finish, high precision, no need of grinding machining and the like, and further improves the installation precision of the product.

Description

technical field [0001] The invention relates to a precision inner diameter stainless steel seamless steel pipe used for hydraulic and pneumatic complete sets of equipment and automation equipment. Background technique [0002] At present, the precision inner diameter seamless steel pipes used for hydraulic and pneumatic complete sets of equipment and automation equipment are mainly made of ordinary carbon steel materials, such as No. 10, 20, 35, and 45 steel, etc. Has a better internal surface finish. However, as the technical performance of hydraulic and automation equipment such as hydraulic and pneumatic cylinders is getting higher and higher, the technical requirements are getting higher and higher. In addition to higher requirements for precision and surface finish, performance requirements such as corrosion resistance and toughness and plasticity have also been put forward. However, seamless steel pipes made of ordinary carbon steel materials can no longer meet these ...
