The material of spacer of choose of Audo Look6.0 download basically depends on following 3 kinds of elements: Temperature, pressure, medium. One. The metal fills up sheet to expect
1. carbon steel:
Recommend temperature of the biggest job not to exceed 538 ℃ , have oxidisability when medium particularly when. High grade the equipment that ground of thin carbon stencil steel does not suit to apply at making neuter or acidity salt solution, the stress that if carbolic steel gets,is in, the equipment accident rate that is used at condition of hot water operating mode to fall is very high. The acid that carbolic steel spacer spends with Yu Gaonong normally and a lot of alkaline solution. Hardness of cloth family name is made an appointment with 120.
2.304 stainless steel
8-10%) of 18-8(chromic 18-20% , nickel, recommend temperature of the biggest job not to exceed 760 ℃ . In temperature - inside 196~538 ℃ interval, easy happening stress is corroded and crystal boundary is corroded. Hardness of cloth family name 160.
3.304L stainless steel
The quantity that contain carbon does not exceed 0. 03% . Recommend temperature of the biggest job not to exceed 760 ℃ . Corrosion resistance can be similar 304 stainless steel. The small amount that contain carbon reduced the separate out of case of carbolic Cong Jing, be able to bear or endure crystal boundary corrodes function prep above 304 stainless steel. Hardness of cloth family name is made an appointment with 140.
4.316 stainless steel
18-12(is chromic 18% , nickel 12%) , about 2% molybdenum increase in 304 stainless steel, can raise its intensity and corrosion resistance when temperature. When temperature rises commonner than other stainless steel is had fight creep function higher. Recommend temperature of the biggest job not to exceed 760 ℃ . Hardness of cloth family name is made an appointment with 160.
5.316L stainless steel
Recommend temperature of the biggest successive job not to exceed ℃ of 760 ℃ ~815. Carbolic content does not exceed the be able to bear or enduring with more outstanding to be being had at 316 stainless steel photograph stress and crystal boundary are corroded. Hardness of cloth family name is made an appointment with 140.
6.2 alloy
45% iron, 24% nickel, 20% chromium and a few molybdenum and copper. Recommend temperature of the biggest job not to exceed ℃ of 760 ℃ ~815. Special apply to make be able to bear or endure vitriolic cankerous equipment, hardness of cloth family name is made an appointment with 160.
7. aluminium
Aluminous (content not under 99%) . Aluminium has outstanding corrosion resistance to be able to be mixed treatment function, apply to make double clip spacer. Hardness of cloth family name is made an appointment with 35. Recommend temperature of the biggest successive job not to exceed 426 ℃ .
