904L Stainless Steel Flat Bar Metal Building Materials Round Bars
2B Surface
Corrosion resistance of 904L stainless steel: because the carbon
content of 904L is very low (maximum 0.020%), there will be no
carbide precipitation under general heat treatment and welding
conditions. This eliminates the risk of intergranular corrosion
after general heat treatment and welding. Because of the high
content of chromium, nickel and molybdenum and the addition of
copper, the 904L can be passivated even in reducing environments,
such as sulfuric acid and formic acid. Among all kinds of
phosphoric acid, 904L has better corrosion resistance than ordinary
stainless steel. In strong oxidizing nitric acid, the corrosion
resistance of 904L is lower than that of high alloyed steel without
molybdenum. In hydrochloric acid, the use of 904L is limited to
1-2% of the lower concentration. In this concentration range. The
corrosion resistance of 904L is better than that of conventional
stainless steel. 904L steel has high resistance to spot corrosion.
In chloride solution, its crevice corrosion resistance is also very
good. The high nickel content of 904L reduces the corrosion rate in
pits and crevices. When the temperature of ordinary austenitic
stainless steel is higher than 60 ℃, it may be sensitive to stress
corrosion in a chloride rich environment. This sensitivity can be
reduced by increasing the nickel content of stainless steel.
