Overview

1.4401 stainless steel tube is an austenitic stainless steel material. Due to the addition of Mo element, 1.4401 stainless steel has greatly improved its corrosion resistance and high temperature strength. The high temperature resistance can reach 1200-1300 degrees, and it can be used under harsh conditions. The main uses of stainless steel 1.4401 are heat exchangers for pulp and paper-making equipment, dyeing equipment, film washing equipment, pipelines, and exterior materials for buildings in coastal areas. It is also used in the field of solenoid valves, mainly for housings, clamps, spheres, valve bodies, valve seats, nuts, valve stems, etc.

Application

Construction encasemnt, doors, windows and armatures, off-shore technology, cisterns and tubes for chemical tankers, production, warehousingand overland transport of chemicals, food and beverages. Due to the Mo-content, good resistance against media containing chlorides and non-oxidising acids. The resistance to intergranular corrosion isguaranteed for larger product thicknesses in the welded condition.

Physical Property

Features

1)The appearance of cold rolled products has good gloss;
2) Due to the addition of Mo (2~3%), corrosion resistance, especially pitting corrosion resistance is excellent
3) Excellent high temperature strength
4) Excellent work hardening (weak magnetic properties after processing)
5) Non-magnetic in solid solution state

6) Good welding performance.

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
