Stainless steel bars have similar resistance to general corrosion as unstable nickel-chromium alloys 304. Prolonged heating in the temperature range of chromium carbide may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications to prevent intergranular corrosion at lower temperatures.
Stainless steel bars have high temperature oxidation resistance, and the oxidation rate is affected by inherent factors such as the exposed environment and product morphology.
The total heat transfer coefficient of the metal depends on other factors, in addition to the thermal
conductivity of the metal. In most cases, the film's heat dissipation coefficient, scale and metal surface condition. Stainless steel keeps the surface clean and tidy. Therefore, its heat transfer is better than other metals with higher thermal conductivity. Stainless steel bar corrosion resistance, bending processability, And a strength stainless steel plate excellent in press workability and a method for producing the same.
Some main grades bars description:
316L: 316 stainless steel contains molybdenum and low carbon content. It has better resistance to pitting
corrosion in marine and chemical industrial environments than 304 stainless steel! (316L low carbon, 316N high nitrogen, high strength, 316F stainless steel with high sulfur content, easy to cut stainless steel.
304L: As a low carbon 304 steel, in general, the corrosion resistance is similar to that of 304, but after
welding or after stress relief, its resistance to intergranular corrosion is excellent, and it can also be used without heat
treatment. Maintain good corrosion resistance.
304: It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties,
good hot workability such as stamping and bending, and no heat treatment hardening. Uses: tableware, cabinets, boilers, auto parts, medical equipment, building materials, food industry (use temperature -196 ° C -700 ° C).
310: The main features are: high temperature resistance, generally used in the boiler, car exhaust pipe. Other properties in general.
303: It is easier to cut than 304 by adding a small amount of sulfur and phosphorus. Other properties are
similar to those of 304.
302: 302 stainless steel rod is widely used in auto parts, aviation, aerospace hardware tools, chemical
industry. The details are as follows: crafts, bearings, sliding flowers, medical equipment, electrical appliances, etc.
Characteristics: 302 stainless steel ball belongs to austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC ≤ 28, with good rust and corrosion resistance.
301: good ductility for molding products. It can also be hardened by mechanical processing. Good weldability.
Wear resistance and fatigue strength are better than 304 stainless steel.
202: belongs to chrome-nickel-manganese austenitic stainless steel, the performance is better than 201
stainless steel.
201: belongs to chrome-nickel-manganese austenitic stainless steel, low magnetic.
410: Martensitic (high-strength chrome steel), good wear resistance and poor corrosion resistance.
420: "cutting grade" martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel.
Also used for surgical knives, it can be done very brightly.
430: ferritic stainless steel, for decoration, for example for car accessories. Good formability, but poor
temperature and corrosion resistance.
Duplex stainless steel 2205 standard No. : ASTM A240/A240M--01 Duplex stainless steel 2205 is a duplex stainless steel consisting of 22% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy.It has high strength, good impact toughness and good overall and local stress corrosion resistance.

The 2507 is a ferrite - austenitic (duplex) stainless steel. It combines the most beneficial properties of many ferrite and austenitic steels. Due to its high chromium and molybdenum content, the steel has excellent resistance to spot corrosion, crevices corrosion and uniform corrosion.The biphasic microstructure ensures that the steel is highly resistant to stress corrosion cracking and has high mechanical strength.
2507 Stainless steel for use in the oil and gas industry;Offshore stone breaker oil platform (heat exchanger tube, water treatment and water supply system, fire protection system, sprinkler system, water stabilization system;Petrochemical equipment;Desalination (desalination) equipment (and the high-pressure pipe in the equipment, seawater pipe);High strength and high corrosion resistance of mechanical and structural components are required;Combustion (waste) gas purification equipment.Main ingredients: 25CR-7Ni-4mo-0.27n
