After heat treatment of stainless steel spring attached to a dense layer of scale, the main composition of this oxide coating is chrome oxide, nickel oxide and chrome iron oxide.
To get rid of this oxide coating, loose scale, erosion and erosion on the surface of the clear spring residue such as three main procedures.
the oxide of the stainless steel spring skin looseness has the following several ways:
1, with nitric acid of 110 grams/liter, soaking at room temperature for an hour or so.
2, with 700 g/l sodium hydroxide solution, heated to 145 ℃ or so, in the spring as anode, with 10 Ann/dm. 2 of current, electrolytic 10 minutes.
3, with 700 g/l sodium hydroxide, with 200 g/l sodium nitrate solution, heated to a temperature of about 145 ℃, soak for an hour.
if you don't loose after descaling process first, even if the etching time is very long, also very difficult to remove it, and can make the base metal from corrosion, because this layer of oxide skin thick, closely.
is frequently used by people in daily life since it can improve leaf spring hardware and leaf spring hardware.
Growing revenue is a common goal for many businesses. We want to be sure Yongqiang include leaders from the marketing, sales and production departments to help make certain that the goals we choose are appropriate and have strong support.
