What is T4003 /3Cr12 stainless steel?

3Cr12 stainless steel sheet is a ferritic stainless steel containing 12% Cr, which is equivalent to the European 1.4003 grade. It is an economical ferritic stainless steel used to replace coated carbon steel, weathering steel and aluminium. It has the characteristics of simple processing and manufacturing, and can be welded by conventional welding technology. It can be used to make: motor vehicle frames, chassis, hoppers, conveyor belts, mesh screens, conveying troughs, coal bins, containers and tanks, chimneys, air ducts, and outer covers , Panels, sidewalks, stairs, rails, etc.

1.4003 stainless steel is typically used in:

Vehicle frames/chassis

Sweeper and glitter vehicles

Bunkers & hoppers

Chimneys & ducting

Walkways, stairs & railings

T.4003 stainless has 250 times the corrosion resistance of mild steels and is particularly good in corrosion/abrasion applications.

Corrosion/Abrasion

The cycle of abrasive removal of a metal surface following surface corrosion rapidly erodes mild/carbon steels even when costly coatings are applied. In wet or damp conditions where abrasion is present type 4003 provides excellent performance by resisting corrosion attack and thus maintaining better flow and slide-ability compared to non-alloyed or low-alloy steels including abrasion resistant grades.

STRENGTH & STIFFNESS

Type 4003 provides good corrosion resistance and excellent abrasion resistance, hence does not need coating or painting systems to be applied for performance reasons. For aesthetic reasons it may be desirable in some applications to apply paint, especially as type 4003 will tend to discolour in corrosive conditions. Type 4003 has exceptional under-paint corrosion resistance and will continue to resist corrosion even where the paint coat has been damaged. Normal preparation is required, such as ensuring a clean surface free of grease and other contamination. A primer coat is recommended for cold-rolled material due to its smoother surface, but hot rolled 1D finish material may be suitably painted in a single coat.
