Stainless Steel 904L, also named as UNS N08904, or En 1.4539, is an expensive stainless steel. It has excellent resistance to reducing acids, pitting and crevice corrosion, as well as various types of stress corrosion cracking and pitting thanks to its high content of nickel and chromium, as well as additives of molybdenum and copper. However, its price is 4 times of the most popular stainless steel grade 304, therefore it is utilized only in the following fields:
· Wiring in electrostatic precipitators
· Oil refinery components
· Seawater cooling devices
· Gas scrubbing plants
· Pulp and paper processing industries
· Acetic, phosphoric and sulphuric acid processing plants
Here pictured below is a customized component ordered by a paper processing industry company. Due to the high price of the metal material, we are not allowed to have any excess material to trim after brake pressing, also the cost to scrap any failure workpiece would be high. We offered our customer a good solution by creating precisely prepared dies and tooling to meet the tight tolerance and reduce the failure possibility to the least.
The customer was happy with our performance and showed their willingness to place repeated order.
We are a professional company to undertake all kinds of and all sizes of metal fabrication works as well as machining works. We have certificates of API，ASME，ABS，DNV，LR which enable us to provide all metalworking service to in the industries of Papermaking, Petrol，Gas，Chemical，Energy，Ship construction，Bridge Building and Machinery Manufacturing.
High quality, low cost, fast delivery, and good service are our commitment and edges. Based in China，help for all the world.
