AISI/SAE 4140 Carbon Steel Bar

AISI/SAE 4140 Carbon Steel Bar

→

4140 is a 1% chromium-molybdenum medium hardenability general-purpose high-strength steel, usually hardened and tempered in the tensile range of 850-1000 Mpa (condition T). 4140 now have improved machinability, which greatly increases feed and/or speed, while extending tool life without affecting mechanical properties. The prehardening and tempering 4140 can be further case hardened by flame or induction hardening and nitriding.

AISI/SAE 4340 Carbon Steel Bar

AISI/SAE 4340 Carbon Steel Bar

→

AISI 4340 alloy steel is a heat treatable low alloy steel containing chromium, nickel and molybdenum. It has high toughness and high strength under heat treatment conditions.

AISI/SAE 5160 Carbon Steel Bar

AISI/SAE 5160 Carbon Steel Bar

→

Steel is a versatile material. One steel alloy is AISI 5160, which is an American Society for Testing and Materials (ASTM) designation for spring steel.

AISI/SAE 8620 Carbon Steel Bar

AISI/SAE 8620 Carbon Steel Bar

→

AISI 8620 alloy steel is a common carburizing alloy steel. This alloy steel is flexible during the hardening process, thus improving the case/core properties.

304 Stainless Steel Bar

304 Stainless Steel Bar

304 stainless steel is a kind of universal stainless steel material, rust resistance than 200 series of stainless steel material is stronger. High temperature resistance is also better, can be as high as 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it is concluded in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of less than or equal to 65% of the boiling temperature. It also has good corrosion resistance to alkali solution and most organic and inorganic acids.

316 Stainless Steel Bar

316 Stainless Steel Bar

→

Grade 316 stainless steel is an austenitic form of stainless steel with a molybdenum content of 2-3%. The addition of molybdenum makes the metal more resistant to pitting and corrosion and improves its resistance to exposure to high temperatures. This grade of stainless steel is particularly effective when used in acidic environments. With this metal, corrosion caused by acetic acid, hydrochloric acid and other forms of acid can be prevented.

316L Stainless Steel Bar

316L Stainless Steel Bar

→

316L stainless steel is an austenitic stainless steel metal alloy that contains nickel and molybdenum, making it corrosion resistant. 316L is a 316 low carbon grade. This grade is not affected by sensitization (grain boundary carbide precipitation). It is often used for large-gauge welded parts (approximately over 6mm). 316L stainless steel has higher creep, fracture stress and tensile strength than chromium nickel austenitic stainless steel at high temperature.

309/309S Stainless Steel Bar

309/309S Stainless Steel Bar

→

309 and 309S are austenitic chromium-nickel stainless steels that are typically used for higher temperature applications. Due to its high chromium and nickel content, 309 and 309S alloys have a high degree of corrosion resistance, excellent oxidation resistance and excellent heat resistance, while providing good strength at room temperature and high temperature. The only significant difference between 309 and 309S is the carbon content. The 309S alloy has less carbon, which minimizes carbide precipitation and improves weldability.

440C Stainless Steel Bar

440C Stainless Steel Bar

→

440C grade stainless steel is a kind of high carbon martensitic stainless steel. High strength, medium corrosion resistance, good hardness and wear resistance. Grade 440C achieves the highest strength, hardness and wear resistance of any stainless steel alloy after heat treatment. Its extremely high carbon content is the reason for these characteristics, which makes the 440C particularly suitable for applications such as ball bearings and valve parts.
