Product Description

N08904/904L/1.4539 Grade Stainless Steel Welded Pipes 2inch 4inch sch40s ERW

Wenzhou Shangle Steel Co., Ltd. (Shangle) founded in 2017,is a comprehensive company integrating industry and trade.As a leading supplier of stainless steel products in Wenzhou, it has a wide range of products in stock that have been rigorously tested and are ready to be shipped.

 

Description:

Grade 904L is Austenitic stainless steel. Compared with 316L, its added molybdenum is more resistant to local chloride erosion (pitting and crevices), especially the added copper is effective against all concentrations of sulfuric acid. Its high alloying content may also make it more resistant to chloride stress corrosion cracking. Its low carbon content makes 904L resistant to welding sensitization and prevents intergranular corrosion.

The 904L alloy is used in piping systems, pollution control equipment, heat exchangers, and bleaching systems.

Welded tube advantage:

1. Uniform wall thickness - the base material is formed strip, with good wall thickness consistency and high surface finish, reaching industrial clean surface level 2B.

2. Low residual stress - the steel pipe after forming uses a high temperature above 1040 degrees for bright annealing of the stainless steel pipe to eliminate stress.

3. High weld strength - welding adopts fusion welding, the material composition is unchanged, after high temperature heat treatment, the weld and the base material have the same intergranular structure, flattening the weld, reverse bending, flaring and other damage experiments, the weld will not appear cracking or cracks, burring and other problems. In addition to eddy current testing and water pressure or gas test to ensure the quality of the pipe.

4. Good consistency - the outer diameter, wall thickness, length and straightness of the pipe are consistent, and the processing accuracy is high
