Classification and Purpose of Capillary Annealing of Stainless Steel

1. Stainless steel capillary annealing classification


Die steel annealing types include annealing, diffusion annealing, isothermal annealing, incomplete annealing, spheroidizing annealing, recrystallization annealing and stress relief annealing. Stainless steel capillary tube radiant heating and cooling system, replacement of fresh air system, ground source heat pump system, low-energy buildings can provide energy-saving and environment-friendly life, bid farewell to traditional air conditioning, the temperature is suitable in the four seasons, only in spring and autumn, and not in winter and summer. By controlling and adjusting the temperature and humidity of the room and the concentration of CO2.


2. Purposes of stainless steel capillary annealing


the main purpose of the is to homogenize the chemical composition and structure of die steel, refine the grain, adjust the hardness, eliminate stress and work hardening, improve the forming and cutting performance of steel, and prepare the structure for quenching. Stainless steel capillary does not contain iron sulfide and is less harmful to human body.


3. Maintenance method of stainless steel capillary tube


We believe that the stainless steel capillary tube is familiar to everyone. The following is a brief introduction to its maintenance method:


(1) The stainless steel capillary tube is wiped off dust every half month.


(2) The process of stainless steel capillary determines its limited performance. Generally, seamless steel pipes have low precision: uneven wall thickness, low brightness inside and outside the pipe, high sizing cost, and pitting and black spots on the inside and outside the pipe are not easy to remove. Can use water for cleaning.


(3) The detection and shaping of stainless steel capillary shall be processed offline. Therefore, it embodies its superiority in high pressure, high strength and mechanical structure materials. Stainless steel coils must not be scrubbed with alcohol!


(4) The material of the stainless steel capillary undergoes elastic and plastic strain under the action of flow force. If the stress is large enough, the stainless steel capillary will break. Clean the stainless steel capillary attention channel; Pay attention to the interface.


(5) Never let the coil contact acidic medium; In case of acidic medium, stainless steel will corrode!
