Ferritic Stainless Steel 3CR12=EN1.4003

1. South Africa developed 3CR12 stainless steel containing 12% Cr, equivalent to 1.4003 grades Europe.

  It is a place of coating for carbon steel, weathering steel and aluminum Cheap ferritic stainless steel.

 

2. 3CR12 stainless steel containing chromium low (11% ~ 12% Cr), carbon and nitrogen content is also very low (C + N0.03%), it can be said 3CR12 is an ultra-chromium ferritic stainless steel. It is the European standard EN10088 1.4003-ASTM.A240 UNSS41003-GB/T1220-1992 00Cr12Ni They have close chemical composition.

 

3. 3CR12 is known as multi-purpose ferritic stainless steel, because it is more applicable than conventional ferrite such as grade 409&430.Traditional ferritic stainless steel is easy to brittle fracture, the maximum thickness is 3mm. Further, 3CR12 toughness, and still maintain high toughness after welding. 3CR12 stainless steel also has good weld ability, welding maximum thickness of 30mm.

 

4. 3CR12 production, with respect to the super-ferritic stainless steel. It is simple; even no VOD vacuum refining furnace, it can also be produced. For example, with Outokumpu AOD production, Columbus Stainless in South Africa by the French Creusot-Loire and the Swedish Uddeholm CLU jointly developed technology to produce ferritic stainless steel, That steam replace expensive argon gas produced decarburization reaction of CO as a dilution medium, with Ukraine GOR technology developed can also be produced.

 

5. Features

  It has moderate corrosion resistance, moderate strength, good weld ability (weld thickness up to 30MM), non-hardened resistance, magnetic, with a moisture resistance and sliding wear. Widely used in various industrial fields of transport, transportation, petrochemical, construction, sugar and mining.

 

6. Scope

  Turbine blades, gold wear plates, roofing, exterior walls, vehicle frame, racing chassis, hopper, conveyor belt, mesh, trough, bunker, containers and containment tanks, chimney, air duct, housings, enclosures, sidewalks, stairs, rails, Walls, roofs, pipelines, cables and envelope, electronic accessories, bridges, gates, sand separator, fences, dams
