Corrosion of AISI Type 304 Stainless Steel in High Temperature Borated Water

PDF Version Also Available for Download.

Description

BS>The corrosion of type 304 stainless steel in water containing boric acid at 600 deg F and 2000 psig and at a flowvelocity of seven feet per second was investigated as a function of boron concentration and of alkaliknity. At a boron concentration of 39 ppm and at a pH value of 10, controlled with lithium hydroxide, no trend of corrosive attack with time was found after the first tw0 days. At a concentration of 41 ppm boron wlth no pH control (pH = 6.9), a regression tyoe equation of the form Y= A + B log (t), was found ... continued below

Description

BS>The corrosion of type 304 stainless steel in water containing boric acid at 600 deg F and 2000 psig and at a flowvelocity of seven feet per second was investigated as a function of boron concentration and of alkaliknity. At a boron concentration of 39 ppm and at a pH value of 10, controlled with lithium hydroxide, no trend of corrosive attack with time was found after the first tw0 days. At a concentration of 41 ppm boron wlth no pH control (pH = 6.9), a regression tyoe equation of the form Y= A + B log (t), was found to express the relationship between corrosive attack and exposure teme. A similiar relationship was found at 1600 ppm boron withthe pH value maintained at 10 using lithium hydroxide. No evidence of raicrostructural attack was observed on coupon specimens under any of the conditions tested. The effects of surface finish and of position were studied. The effect of orientation of the rolling directon of coupon specimens with respect to the direction of fluid flow was also investigsted. (auth)
