304L Stainless Steel Bar

304L is one of the austenitic stainless steels with a chromium content of at least 18%, a nickel content of at least 8%, and a maximum carbon content of 0.03. 304L stainless steel is an ideal choice for various household and commercial applications, with excellent corrosion resistance, ease of manufacturing and excellent formability. Austenitic stainless steels are also considered to be the easiest to weld among high alloy steels and can be welded by all fusion and resistance welding processes.

AISI/SAE 1025 Carbon Steel Bar

1025 carbon steel is a steel that contains only carbon as its main alloying element. These steels also contain 0.4 percent silicon and 1.2 percent manganese. Small amounts of copper, nickel, molybdenum, aluminum and chromium can also be detected in carbon steel.

AISI/SAE 1045 C45 Carbon Steel Bar

1045 is characterized by medium carbon, medium tensile strength steel, which has quite good strength, machinability and reasonable weldability under hot-rolled conditions. 1045 round steel can be provided with hot rolling, cold drawing, rough turning or turning and polishing. By cold-drawing the 1045 steel bar, the mechanical properties can be improved, the dimensional tolerance can be improved, and the surface quality can be improved.

AISI/SAE 4130 Carbon Steel Bar

4130 cold-rolled round bars provide some recognized weldability without affecting the wear and impact resistance of the steel, carbon steel 4130 bars also have excellent machining properties and can be heat treated. At the same time, it has high tensile strength and high yield strength.

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 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

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