Can H0Cr21Ni10 welding wire be used for welding cCr18Ni10Ti steel of the same type?
For welding of 0Cr18Ni10Ti steel to itself, H0Cr21Ni10Ti should be used; for welding of 0Cr18Ni9 steel to itself, H0Cr21Ni10 should be employed. This is specified in JB/T4709. However, in my opinion, when welding 0Cr18Ni10Ti steel together and H0Cr21Ni10Ti is not available, using H0Cr21Ni10 is also acceptable
Try to follow the regulations to ensure that the alloy content of the weld metal is essentially the same as that of the base material.
It is necessary to ensure that the metal alloy content of the weld seam is essentially the same as that of the base material
It is necessary to ensure that the metal alloy content of the weld seam is essentially the same as that of the base material. When welding steel of the same type such as 0Cr18Ni10Ti, wire H0Cr21Ni10 should not be used, as this will reduce the performance of the material. Unless the design considers that the reduced performance does not affect usability.
