Low Temperature Plain Steel
- Aug 13, 2018 -

Ferritic low temperature steels are classified into three types according to their components

Low temperature steel ending low carbon manganese steel

Low carbon manganese steel (C0.05 ~ 0.28%,Mn0.6 ~ 2%).Make Mn/C (10), reduce harmful impurities such as oxygen, nitrogen, sulfur and phosphorus, and add some elements such as aluminum, niobium, titanium and vanadium to refine grains.This kind of steel lowest temperature is about 60 ℃.

Low temperature steel spur low alloy steel

Low alloy steel.There are mainly low nickel steel (Ni2 ~ 4%), manganese nickel molybdenum steel (Mn0.6 ~ 1.5%,Ni0.2 ~ 1.0%, Mo0.4 ~ 0.6%, C < 0.25%), nickel chromium molybdenum steel (Ni0.7 ~ 3.0%, Cr0.4 ~ 2.0%, Mo0.2 ~ 0.6%, C < 0.25%).The steel strength higher than that of low carbon steel, the lowest temperature can reach to 110 ℃ or so.China has developed several kinds of low temperature low alloy steels for nickel reduction, such as 09Mn2V.

Low temperature steel medium (high) alloy steel

Medium (high) alloy steel.There are 6%Ni steel, 9%Ni steel, 36%Ni steel, of which 9%Ni steel is widely used for cryogenic purpose.The use of such high nickel steel temperature as low as - 196 ℃.
