A36 is a low-carbon steel containing trace amounts of manganese, phosphorus, sulfur, silicon and other elements such as copper. A36 has good weldability and high yield strength, and is the most specified structural steel plate by engineers. ASTM A36 is most commonly manufactured as a variety of structural steel parts. This grade is used for welded, bolted or riveted construction of bridges and buildings, as well as for general structural purposes. Due to its lowest yield point, A36 can be used to design lighter-weight structures and equipment, and provide good weldability.
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 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.
A572 steel bars are lightweight, but have good strength, ductility and workability, making them ideal for structural applications. These characteristics make the A572 relatively simple to shape into different structures, while maintaining the ability to withstand large stresses and loads.
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.
