usage of NM400 steel plate cold working and aging
321 stainless steel has excellent high-temperature stress rupture performance and high-temperature creep resistance, stress mechanical properties, are better than 304 stainless steel. Austenitic stainless steel is equivalent to the Chinese grade 0Cr18Ni10Ti. 321 stainless steel is Ni-Cr-Mo austenitic stainless steel, its performance is better than 304. Due to the addition of titanium metal, , 321 stainless steel plate and sheet have better resistance to grain boundary corrosion and high temperature strength,usage of NM400 steel plate.
Usage of NM400 steel plate,The Performance requirements of low alloy structural steel, usage of NM400 steel plate:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.
Titanium microalloying is an element of strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
