Introduction
321 stainless steel, Ni-Cr-Mo-type austenitic stainless steel, its performance with a 304 stainless steel plate is very similar, but due to the addition of titanium, it has a better intergranular corrosion resistance and high temperature strength. The addition of titanium to make it effective control of the formation of chromium carbide .

321 stainless steel with Ti as a stabilizing element exists, but it is the creep strength of steel at high temperatures much better than 316L.

Hot-rolled plate
1. Toughness and poor surface roughness, the price is low;
2. The temperature of hot rolling is similar to the forging temperature;
3. Hot plate with hot rolling surface oxide processing, thickness difference
4. Hot-rolled product prices and the use of relatively cold to a wide range of more;
5. Hot-rolled steel, mechanical properties far less than cold, but also inferior to forging processing, but have good toughness and ductility
6. The surface of the hot-rolled plate without plating is dark brown
7. From the plating can be distinguished from the degree of surface smoothness, hot rolled plate smoothness is low.

Application
321: High inter-granular corrosion resistance of chemical, coal, oil field open machine, heat treatment difficulties of building heat-resistant parts
1. Oil and gas burning pipeline
2. Engine exhaust pipe
3. Shell of the boiler, heat exchangers, heating furnace part
4. Silencer for diesel parts
5. Boilers and pressure vessels
6. Chemical transportation vehicle
7. Expansion joint
8. Furnace pipes and drying machines for spiral welded pipe
