1.4003 3Cr12 stainless steel plate
We are 1.4003 3Cr12 stainless steel plate supplier. 3Cr12 is a weldable ultra-low carbon, low-chromium ferritic stainless steel developed by the current South African Columbus Stainless Steel Company in the early 1980s. It has moderate corrosion resistance, moderate strength and good solderability. It is an economical stainless steel widely recognized in the world.Due to its good performance, it is widely used in various industrial fields such as material transportation, transportation, sugar, structure, petrochemical, mining. Specifically applicable to: motor vehicle frames, chassis, hoppers, conveyor belts, mesh screens, conveyors, coal bunkers, containers and tanks, chimneys, ducts, enclosures, cabinets, sidewalks, stairs, tracks, etc.
1. Process: EAF steel - AOD furnace smelting - continuous casting - annealing - heating - plate rolling - finished products - human pool.
2. Using ultra-low carbon stainless steel by continuous casting process, C and N should be reduced to a lower level during the refining process, and the increase of these two elements in the continuous casting process should be avoided. Protective casting must be achieved during continuous casting.
3. The characteristics of ferritic stainless steel are: low temperature strength, high crystallization speed, very well-developed columnar crystals, and easy to crack in the subsequent hot working and cold working. Therefore, in terms of processes, equipment, etc., it is necessary to suppress the growth of columnar crystals and increase the proportion of equiaxed crystals.
4. Ferritic stainless steel must be strictly controlled after hot rolling or annealing to avoid 370-550 degrees Celsius temperature fragile areas. Therefore, the heat treatment process must be strictly controlled to quickly pass the temperature zone.
5. The chemical composition of the steel is different from 00Cr12 in CB4237-92, and the Ni and N regulations are added. Ni and N are elements of the austenite region of the large iron-chromium alloy, which may cause the tissue to be produced in the high temperature region. Two-phase zone. Therefore, there is a greater difficulty in continuous casting and hot working.
