T4003, equivalent to the European standard 1.4003, is a practical ferritic stainless stee  l, often used in place of low carbon steel. Around 2008, [TJC STEEL]TICO introduced and developed this brand for C80B stainless steel heavy load coal trains.

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.
