Among the 321 stainless steel wire , Ti exists as a stabilizing element, but it is also a heat-strength steel, which is much better than 316L in high temperature. 321 stainless steel wire is in organic acid and inorganic acid of different concentrations and different temperatures, especially in It has good abrasion resistance in oxidizing medium and is used to manufacture lining and conveying pipeline of wear-resistant acid container and wear-resistant equipment.
The 321 stainless steel wire is a Ni-Cr-Ti type austenitic stainless steel, and its performance is very similar to that of 304, but it has better resistance to intergranular corrosion and high temperature strength due to the addition of titanium metal . Due to the addition of titanium metal, it effectively controls the formation of chromium carbide.
321 stainless steel wire has excellent high temperature stress breaking (Stress Rupture) performance and high temperature creep resistance (Creep Resistance) stress mechanical properties are better than 304 stainless steel . Suitable for welding components used at high temperatures.
Stainless steel does not cause corrosion, pitting, rust or wear. Stainless steel is also one of the strongest materials in construction metal materials. Because stainless steel has good corrosion resistance, it enables structural components to permanently maintain engineering integrity. Chrome-containing stainless steel also collects machinery.
321 stainless steel wire is used in field open-air machines for chemical, coal and petroleum industries with high resistance to intergranular corrosion, heat-resistant parts for building materials and parts with difficult heat treatment, such as:
1. Petroleum waste gas combustion pipeline
2. Engine exhaust pipe
3. Boiler casing, heat exchanger, furnace components
4. Dust-proof parts for diesel engines
5. Boiler pressure vessel
6. Chemical transport vehicles
7. Expansion joint
8. Spiral welded pipe for furnace pipe and dryer
