Material Characteristics:
The T4003 offers a range of benefits of ferritic stainless steels such as strength, corrosion and wear resistance, weldability, formability, good durability [TJC STEEL]and lower maintenance.
Applications:
In China,T4003 is mainly used for railway freight car body, the product form is plate coil, TISCO's market share accounts for more than 90%.As a good low cost stainless steel solution, the T4003 is also used in sweeps, gravel vehicles, tanks, [TJC STEEL]chimney pipes, staircases, railings, etc.
