    Description about 321/321H stainless steel

    It maintains good resistance to intergranular corrosion at temperatures up to 800-1500 °F (427-816 °C) and chromium carbide precipitation. Due to the addition of titanium to the composition, 321 Hot rolled Stainless steel plate can still maintain stability in the case of chromium carbide formation.

     321 Hot rolled Stainless steel plate has advantages in high temperature environment due to its excellent mechanical properties. Compared with 304 alloy, 321 alloy stainless steel has better ductility and resistance to stress fracture. In addition, 304L can also be used for anti-sensitization and intergranular corrosion. 

    General attribute

    Alloy 321 (UNS S32100) is a very stable stainless steel. It maintains good resistance to intergranular corrosion at temperatures up to 800-1500 °F (427-816 °C) and chromium carbide precipitation. Due to the addition of titanium to the composition, 321 Hot rolled Stainless steel plate can still maintain stability in the case of chromium carbide formation. Alloy 347 is due to the addition of niobium and tantalum to maintain its stability. .

    Alloys 321 and 347 are commonly used for long-term operation at 800-1500 °F (427-816 °C) in high temperature environments. If the application involves only welding or short-time heating, replace it with 304L.

    The high temperature operation advantages of 321 and 347 alloys also depend on their good mechanical properties. Compared with 304, 304L, 321 and 347 have better creep stress and stress crack resistance. This allows the pressure of these stable alloys to meet the American Society of Mechanical Engineering boiler regulations and pressure vessel specifications at a higher temperature. Therefore, the maximum operating temperature of 321 and 347 alloys is 1500 °F (816 °C), while 304, 304L is limited to 800 °F (426 °C).

    321 and Alloy 347 also have high carbon content, their UNS numbers are: S32109 and S34709.

    410 410s Hot rolled Stainless steel Plate

    What is the difference between 409 and 410 stainless steel:

    409—except for the addition of titanium, the cheapest model, usually used as a car exhaust pipe, is a ferritic stainless steel (chrome steel), suitable for welding, low cost, steam locomotive exhaust pipe, and fire row

    410—Martensite (high-strength chrome steel), good wear resistance and poor corrosion resistance, suitable for pumping. Its chemical composition contains 13% chromium, 0.15% or less carbon and a small amount of other elemental alloys. The raw material is cheaper, magnetic, and hardenable by heat treatment. General uses include bearings, medical appliances and tools and appliance panels, and tensile parts.

    410 430 430F 430LX  stainless steel

    410 stainless steel is equivalent to China’s 1Cr13 stainless steel S41000 (American AISI, ASTM). 0.01% carbon, 0.13% chromium 0.1 410 stainless steel: good corrosion resistance, machinability, general purpose blades, valves.

    Heat treatment of 410 stainless steel: solution treatment (°C) 800-9000 slow cooling or 750 fast cooling

    430 stainless steel has good corrosion resistance and general steel grade, thermal conductivity is better than austenite, thermal expansion coefficient is smaller than austenite, heat fatigue, adding stabilizing element titanium, and the mechanical properties of the weld site are good. For building decoration, fuel burner parts, household appliances, home appliances parts.

    The 430F is a grade of steel with a free-cutting property on 430 steel. Used in automatic lathes, bolts and nuts.

    430LX adds Ti or Nb to 430 steel, lowers C content, and improves processability and weldability. Used in hot water tanks, hot water systems, sanitary appliances, household durable appliances, bicycle flywheels, etc.

    430 Hot rolled Stainless steel plate

    Comparison of 304 stainless steel and 430 stainless steel:

    1. Corrosion resistance: 430 stainless steel contains 16.00-18.00% chromium, which is basically free of nickel metal. 304 stainless steel contains more chromium and nickel metal, so 430 stainless steel corrosion resistance is better than 304 stainless steel.

    2. stability: 430 stainless steel is ferrite, 304 stainless steel is austenitic, 304 stainless steel is more stable than 430 stainless steel,

    3.toughness: 304 stainless steel has a strong toughness, stronger than 430 stainless steel

    4.thermal conductivity: 430 stainless steel ferrite is better than 304 stainless steel austenitic heat transfer performance,

    5.mechanical properties: 430 stainless steel added a stable chemical element of titanium, the mechanical properties of the weld site is better than 304 stainless steel.

    Simple Description about polished stainless steel sheet price

    For the flat Stainless steel, usually be polished as sheets also mean the thin thickness one, but sometime the thicker plate be need be polished for special application. And most of plate be polished by mechanical polishing way.

    Stainless steel commonly used polishing method

    Currently commonly used methods are: electrolytic polishing, electrochemical polishing, mechanical polishing

    The electrochemical polishing process is divided into two steps: (1) Macro leveling: the dissolved product diffuses into the electrolyte, and the surface roughness of the material decreases, Ral μm. (2) Low-light leveling: Anodic polarization, surface brightness is improved.

    Stainless steel commonly used polishing method

    Currently commonly used methods are: electrolytic polishing, electrochemical polishing, mechanical polishing

    The electrochemical polishing process is divided into two steps: (1) Macro leveling: the dissolved product diffuses into the electrolyte, and the surface roughness of the material decreases, Ral μm. (2) Low-light leveling: Anodic polarization, surface brightness is improved.

    Electrolytic polishing: using an acidic electrolyte (strong acid), the sample to be polished is placed in a post-current (about 7 mA), and the anode is dissolved. Due to the magnitude of the current, the protruding portions dissolve more quickly, and the surface tends to be flat, reaching the final Polished effect (the effect can be seen within about 10 minutes). The basic principle of electropolishing: the same as chemical polishing, that is, by selectively dissolving the tiny convex part of the surface of the material to make the surface smooth. Compared with chemical polishing, the effect of the cathode reaction can be eliminated, and the effect is better.

    Mechanical polishing: For the rough surface of the stainless steel plate to achieve the decorative effect must be: the roller frame is polished with a belt polishing machine, first with 120# abrasive belt, throw the surface color one to the time, change the 240# abrasive belt, throw it to the surface When the color is up, change the 800# abrasive belt and throw it to the surface color one time. Then change the 1200# abrasive belt and throw the effect of decorating the stainless steel plate.
