It is preferable to mix it so that it contains 0.03% by weight.If the blending ratio is 0.3% by weight without grooves, a sufficient rust prevention effect cannot be obtained, and if it exceeds 1.0% by weight, the moldability will be poor. This is undesirable as it reduces the strength of the target.
