Product Description

Super austenitic stainless steel (904L stainless steel plate) is a kind of high alloying austenitic stainless steel with low carbon content. It has good corrosion resistance in dilute sulfuric acid and is specially designed for the environment with harsh corrosion conditions. It has high chromium content and sufficient nickel content. The addition of copper makes it have strong acid resistance, especially high resistance to chloride gap corrosion and stress corrosion cracking.It is not easy to appear corrosion spots and cracks. Its pitting resistance is slightly better than that of other steels. It has good processability and weldability and can be used for pressure vessels

Matters Needing Attention

(1) welding performance

Like general stainless steel, 904L can be welded by various welding methods. The most commonly used welding method is manual arc welding or inert gas shielded welding. The welding rod or welding wire metal is based on the composition of the base metal and has higher purity. The content of molybdenum is required to be higher than that of the base metal. Generally, preheating is not required before welding. However, in cold outdoor operation, in order to avoid condensation of water vapor, the joint or adjacent area can be uniformly heated.Note that the local temperature should not exceed 100 ℃ to avoid carbon accumulation and intergranular corrosion.

Small linear energy, continuous and fast welding speed should be adopted during welding.Generally, heat treatment is not required after welding. If heat treatment is required, it shall be heated to 110 ~ 1150 ℃ and cooled rapidly.

(2) machining performance

The machining characteristics of 904L are similar to those of other austenitic stainless steels, and there is a tendency to stick to the tool and work hardening during machining.It is required to use positive rake angle cemented carbide tools and use sulfide and chlorinated oil as cutting coolant. The equipment and process shall be based on the premise of reducing work hardening.

Slow cutting speed and feed rate shall be avoided during cutting.

3. Production process

As a general-purpose corrosion-resistant material, 904L stainless steel plate can obtain high-performance products after cold rolling, and can be used in many fields including food industrial equipment, kitchen utensils and electronic industry. The applications of various fields are different, and the performance requirements of cold-rolled stainless steel 904L stainless steel plate are also different.

Especially when the thickness of stainless steel strip is small, it is extremely important to seek its comprehensive cold working performance. By analyzing the influence of rolling and annealing process on its properties and properties, and studying the influence of production process parameters on its structure and properties, we can provide experimental data for optimizing production and improving properties.
