Introduction
904L Super austenitic stainless steel of low carbon and high nickel, molybdenum austenitic stainless and acid-resistant steel, for the introduction of France h • S the company's proprietary material.
---a good change activation-deactivation capabilities, excellent corrosion resistance, non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid and has good corrosion resistance, in the neutral medium containing chloride ions has a good resistance to pitting, has a good resistance to crevice corrosion and stress corrosion performance.
---Applies to 70 ℃ the following kinds of concentrated sulfuric acid at atmospheric pressure under any concentration, temperature of acetic acid and formic acid and acetic acid corrosion resistance is also very good.

Hot-rolled plate
1. Toughness and poor surface roughness, the price is low;
2. The temperature of hot rolling is similar to the forging temperature;
3. Hot plate with hot rolling surface oxide processing, thickness difference
4. Hot-rolled product prices and the use of relatively cold to a wide range of more;
5. Hot-rolled steel, mechanical properties far less than cold, but also inferior to forging processing, but have good toughness and ductility
6. The surface of the hot-rolled plate without plating is dark brown
7. From the plating can be distinguished from the degree of surface smoothness, hot rolled plate smoothness is low.

Application
* Petroleum and petrochemical equipment, petrochemical equipment in the reactor.
* Sulfuric acid storage and transportation equipment, such as heat ex-changers, and so on.
* Power plant flue gas desulfurization equipment, mainly using parts: absorber Tower, flue, stall doors, trim, sprinkler systems, etc.
* Organic acid scrubber and the fans in the system.
* Sea-water treatment plant, seawater heat ex-changers Equipment for the paper industry, sulfuric acid and nitric acid equipment, pharmaceutical industry of sulfuric acid and other chemical equipment, pressure vessels, food equipment.
* Pharmaceutical factory: centrifuge, reactor, and so on.
* Plant foods: soy sauce pots, cooking wine, salt shakers, equipment and dressing.
