Potential Value

<p>This study aimed to analyze the effect of adding to the rate of steel corrosion inhibitor and comparing the rate of corrosion on steel pipes with and without inhibitors.The testing conducted in Puspitek shown that the most optimum inhibitor contained in the addition of 1% due to changes in the price of the original acidity (pH) from 7.30 to 11.80. This shows the increasing of pH occurred sizable value and followed by the declines of potential value (Ecorr) -700.53 mV to -512.39 mV. Thus, the  decreasing accured to the current corrosion value (Icorr) from 2.71 μA/cm<sup>2</sup> to 0.31 μA/cm<sup>2</sup>, while the corrosion rate of carbon steel St 41 decreased most effective after adding 1% Na<sub>2</sub>CO<sub>3</sub> as inhibitor, the corrosion rate is changed from 1.2437 mpy to 0.1427 mpy.</p>

Abstract AK Steel 409 Ultra Form was created for applications needing oxidation or corrosion protection beyond the capability of carbon steel and some coated steels. AK Steel 409 Ultra Form is more formable than standard Type 409 stainless steel and is particularly suitable for parts requiring more complex shapes and improved weldability. Examples of applications include automotive exhaust tubing and stampings. This datasheet provides information on physical properties, hardness, elasticity, and tensile properties as well as deformation. It also includes information on high temperature performance as well as forming and joining. Filing Code: SS-990. Producer or source: AK Steel, Butler Operations.
