—— Regan Bell

Not bad, the quality is good, and the speed is fast!

—— Shafeeq Shukoor

The product quality is good, but your price will be higher than the price I got from other places, but it is within the acceptable range.

—— Morteza

The goods are received. Yours are very close to the products I imported from Germany, but the prices are much lower.

—— Marty Higdon

Our customers are very demanding and picky about quality, but after seeing your products, they hardly believe that they were imported from China, which is amazing.

—— Uwe Nolte

This is my first time importing products from China. Before that, I dared not try them easily, but I was very satisfied after receiving your goods.

—— Njabulo Mabaso

Thank you for your full assistance in the delivery process, so that we can receive the goods quickly and save a lot of time.

—— Luzuko Ntsomi

904L corrosion resistance
Since the carbon content of 904L is very low (maximum 0.020%), there is no carbide precipitation in the case of general heat treatment and welding. This eliminates the risk of intergranular corrosion after general heat treatment and welding. Due to the high chromium-nickel-molybdenum content and the addition of copper, 904L can be passivated even in a reducing environment, such as sulfuric acid and formic acid.


The high nickel content makes it have a lower corrosion rate in the active state. In pure sulfuric acid in the concentration range of 0~98%, the use temperature of 904L can be as high as 40 degrees Celsius. In pure phosphoric acid in the concentration range of 0~85%, its corrosion resistance is very good. In industrial phosphoric acid produced by the wet process, impurities have a strong influence on corrosion resistance. Among all kinds of phosphoric acid, 904L has better corrosion resistance than ordinary stainless steel. Among the highly oxidizing nitric acid, 904L has lower corrosion resistance than high-alloy steel grades that do not contain molybdenum. In hydrochloric acid, the use of 904L is limited to a lower concentration of 1-2%. In this concentration range. The corrosion resistance of 904L is better than conventional stainless steel.


904L steel has high resistance to pitting corrosion. Its resistance to crevice corrosion in chloride solutions is also very good. The high nickel content of 904L reduces the corrosion rate at pits and crevices. Ordinary austenitic stainless steels may be sensitive to stress corrosion in a chloride-rich environment at temperatures above 60 degrees Celsius. This sensitization can be reduced by increasing the nickel content of the stainless steel. Due to the high nickel content, 904L has high resistance to stress corrosion cracking in chloride solution, concentrated hydroxide solution and hydrogen sulfide-rich environment.
