304 SS hexagonal bar features
A, 304 hexagonal bar:
304 stainless steel hexagonal rods is a kind of common stainless steel materials, corrosion prevention is better than 200 series stainless steel materials. High resistance to high temperature also is better, can to 1000-1200 degrees. Stainless steel hexagonal rods with excellent corrosion and corrosion resistance and better performance of resistance to intergranular corrosion. For oxidizing acid, obtained in the experiment, the concentration of 65% or less of boiling temperature in nitric acid, the stainless steel hexagonal rods have strong corrosion resistance. To most organic and inorganic acid and alkali solution with good corrosion resistance ability.
The corrosion resistance of the stainless steel hexagonal rods first depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the arrangement of the internal layout, the first effect is chromium element. Chromium has the very high chemical stability, can form a passivation film on steel surface, make the metal block with the outside world, maintenance of steel plate are not oxidation, corrosion resistant to add steel plate. After passivation membrane damage, corrosion resistance.
Second, stainless steel hexagonal rods use:
304 stainless steel is widely used in boilers, energy (nuclear power, thermal power, fuel cell), industrial furnaces, incinerator, heating furnace, chemical, petrochemical, petroleum, electronics, chemical industry, medicine, textile, food, machinery, building, nuclear power, aerospace, military industry and other industries, and other important areas.
304 hexagonal rods of low thermal expansion rate, forming type and good oxidation resistance Used for heat resistant utensils, burners, household appliances products, 2 kinds of tableware, kitchen sink. The price is low, good workability is an ideal substitute for SUS304; Miles erosion resistance is good, the typical athermal freedom of sclerosing stainless steel iron element system.
Grain boundary corrosion of 304 stainless steel hexagonal rods used in demanding outdoor in the field of chemical, coal, petroleum industry machinery, building materials heat-resistant parts and heat treatment are difficult parts;
