321 Stainless Steel Bar

321(UNS S32100) is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has good intergranular corrosion resistance at a chromium carbide precipitation temperature of 800-1500 °F(427-816°C). The alloy is resistant to oxidation at 1500 °F(816°C) and has higher creep and stress rupture properties than the 304 and 304L alloys. It also has good low temperature toughness.

330 Stainless Steel Bar

330 is an austenitic nickel-chromium-iron-silicon alloy with excellent oxidation and carburizing properties up to 2200 °F and high strength. The high nickel and chromium content of the alloy provides excellent oxidation resistance and carburization, and the silicon content further improves the oxidation resistance of the alloy. The ultra-high nickel content of 34 to 37% of the alloy 330 also provides high resistance to chloride stress corrosion cracking and embrittlement due to sigma phase precipitation in most furnace atmospheres. The alloy 330 also has a low coefficient of expansion, excellent ductility and high strength.

347 Stainless Steel Bar

347 is a stable austenitic chromium steel, containing niobium, which can eliminate carbide precipitation, thereby eliminating corrosion during the year. 347 is stabilized by the addition of chromium and tantalum, and provides higher creep and stress rupture properties than alloys 304 and 304L, which can also be used for sensitization and exposure to corrosion problems during the year. The addition of niobium also makes the 347 alloy have excellent corrosion resistance, even better than the 321 alloy.

403 Stainless Steel Bar

403 stainless steel has excellent mechanical properties, including high hardness, high strength and high wear resistance. It is commonly used in the manufacture of high hardness tools, cutting tools, bearings and valves and other industrial parts, especially in applications requiring corrosion resistance and wear resistance. In addition, 403 stainless steel can also be used in food processing equipment, chemical equipment, medical equipment and other fields to meet the requirements of corrosion resistance and mechanical properties.

405 Stainless Steel Bar

The mechanical properties of 405 stainless steels are important in determining their suitability for various applications. This steel has excellent workability and is easy to cut and shape into different shapes. In addition, the material exhibits a good level of strength and hardness, making it wear-resistant and tear-resistant. A remarkable characteristic of 405 stainless steel is its ductility, which refers to its ability to deform under pressure without breaking. This property makes the metal suitable for forming processes such as bending and rolling without cracking or breaking.

409 Stainless Steel Bar

409 is a general purpose chromium, titanium stabilized ferritic stainless steel, its main application is automotive exhaust systems. It contains 11% chromium, which is the lowest amount to form a passive surface film, which makes stainless steel corrosion resistant. It combines good high temperature corrosion resistance, medium strength, good formability and overall cost. Compared with carbon steel, 409 has strong corrosion resistance and is used as a substitute for carbon steel in mildly challenging environments. In this environment, its high resistance to corrosion and high temperature oxidation has advantages. It is usually used in applications where appearance is a secondary quality to mechanical properties and corrosion resistance.

410 Stainless Steel Bar

410 is a basic general-purpose martensitic stainless steel, used for high-stress parts, with good corrosion resistance and high strength and hardness. The alloy 410 contains at least 11.5 percent chromium, which is just enough to exhibit corrosion resistance in mild atmospheres, vapors, and many mild chemical environments. It is a general-purpose grade, usually provided in a hardened but still processable condition, for applications that require high strength, medium heat resistance and corrosion resistance. After the 410 is hardened, tempered and polished, it shows the greatest corrosion resistance.

416 Stainless Steel Bar

416 is a martensitic free-working chromium steel alloy, which is generally considered a first free-working stainless steel. It has the highest machinability of any stainless steel, about 85% of free-machining carbon steel. Martensitic stainless steels are designed to harden by heat treatment and have corrosion resistance. Although the corrosion resistance of 416 alloy and other martensitic stainless steels is not as good as that of austenitic or ferritic stainless steels, it still exhibits good corrosion and oxidation resistance and high strength in hardened and tempered conditions.

420 Stainless Steel Bar

420 is a hardenable martensitic stainless steel that contains at least 12% chromium, just enough to provide corrosion resistance. It has good ductility in the annealed condition, but can be hardened to a minimum Rockwell hardness of 50 HRC, which is the highest hardness in the 12% chromium scale. Due to its hardening properties, 420 are not often welded, although this is possible. Martensitic stainless steel is designed for high hardness, and sometimes other properties will be affected to a certain extent. The corrosion resistance is lower than that of ordinary austenite grades, and its effective operating range is limited by its ductility loss at sub-zero temperatures and strength loss due to excessive tempering at high temperatures. The best corrosion resistance is obtained when the metal is hardened and subjected to surface grinding or polishing.
