What is the difference between carbon steel elbow

What is the difference between carbon steel elbow and stainless steel elbow  

Our company introduce the difference between carbon steel elbow and stainless steel elbow.  Many friends will ask what is the difference, carbon steel elbow used there?  They're different there, right? What medium should stainless steel elbows be used for pipes?  Our company analyzes it for you:  

Carbon steel elbow is also ordinary iron elbow, easy to rust, after welding, need to do external paint anti-corrosion treatment.  Carbon steel elbow commonly used processing materials are :20#, A3, Q235, Q235A, Q235B, 20G, 16Mn, ASTM A234WPB, ASTM A105, etc.  

Stainless steel elbow is usually on the basis of carbon steel increased chromium Cr, Nickel Ni, Mo Mo and other alloy components, strength and toughness index is stronger than carbon steel elbow, corrosion resistance acid and alkali rust.  Stainless steel elbow commonly used manufacturing materials are :304, 304L, 316, 316L, S30408, S30403, S31608, S31603, SUS304, ASTM  A403, TP321, TP317L, 0Cr18Ni9, 00Cr19Ni10, 00Cr17Ni14Mo2, 1Cr18Ni9Ti, 06Cr17Ni12Mo2, 022Cr17Ni12Mo2, etc.  

Carbon steel elbow straight seam carbon steel elbow and seamless carbon steel elbow, carbon steel elbow because of the low cost of manufacturing base material so the price is relatively cheap, in the use of medium requirements are not high often choose carbon steel elbow.  Stainless steel elbow rust, corrosion, acid and alkali resistance is better, the price is higher than carbon steel elbow.  Select materials according to the actual use of the project.  Material quality is to choose the right steel according to the design requirements or pipeline medium, rather than simply according to the price of steel.
