439 Oxidation resistance and corrosion resistance is superior to Type 409 in areas where temperatures may exceed the oxidation limit of Type 409 or where aqueous corrosion resistance, particularly to chlorides, is needed. Applications include: Tubular manifolds and other exhaust system with difficult to form exhaust components.
| Ti= [4 * (C+N) + 0.15] to 0.80 Stabilisation may be by use of titanium or niobium or zirconium. According to the atomic mass of these elements and the content of carbon and nitrogen, the equivalence shall be the following: Nb (% by mass)=Zr (% by mass) = 7/4 Ti (% by mass) Elements not listed in this table shall not be intentionally added to the steel without the agreement of the purchaser except for finishing the cast. Particular ranges of sulphur content may provide improvement of particular properties. For machinability a controlled sulphur content of 0.015 % to 0.030% is recommended and permitted. For weldability, a controlled sulphur content of 0.008 % to 0.030 % is recommended and permitted. For polishability, a controlled sulphur content of 0.015 % max is recommended. |
