machining low and medium carbon steel alloys
Alloy steels and carbon steels can be designated with specific grades by a four-digit AISE/SAE numerical index system. The system is based on the chemical compositions of the steels and alloys. Example AISI/SAE No. 1020. the first digit indicates that this is plain carbon steel. the second digit indicates there are no alloying elements
Alloy Steel. This is really where it gets fun. There are generally two categories of alloy steel:low alloy and high alloy. Anything with less than an 8% alloying element is labelled as low alloy, anything over 8% is high alloy. Low alloy steels are by far the most common. CNC Steel Material CNC Machining Steel Fictiv1045 Carbon Steel is stronger than low carbon steel (1018 Steel) but is easy to machine. It is heat treatable and can be used for bolts, studs and shafts. 4130 Alloy Steel is similar to 4140 Alloy Steel but offers better weldability and has a slightly lower carbon content. It is best suited for gears and other structural applications.
Carbon & Low Alloy Steel Investment Casting Materials. Carbon and Low alloy steel castings are ideal for general engineering purposes. They can be used in a wide variety of low and medium strength applications and provide useful general properties at a relatively low cost. For more information please see table BS3146 (1974), Part 1. Carbon Steel Alloys Coburn-MyersFeatures and applications of common carbon steel alloys. Low carbon steels generally contain less than 0.25% carbon and cannot be strengthened by heat-treating (strengthening can only be accomplished through cold working). The low carbon material is relatively soft and weak, but has outstanding ductility and toughness.
Apr 07, 2013 · Medium carbon steels These steels are similar to low C steels except that the C content in these steels are higher and normally in the range of 0.31% to 0.6 % and the Mn content in the range of 0.6 % to 1.65 %. Due to Increased C content, the medium C steels can be used in the quenched and tempered condition. Free-Machining vs. Welding:A Manufacturing Dilemma Low and medium carbon steel for machining consists of ferrite and spheroidized cementite or ferrite and pearlite. Ferrite is a soft material and cementite is a hard material. Pearlite is a composite consisting of plates of ferrite and cementite. The amount of cementite or pearlite in a steel increases as the steel carbon content increases.
Tool steels:Carbon steels (0.90-1.30%) and low/medium alloy steels loose their hardness above 400 °F through tempering Low/medium alloy steels also lose their hardness above 300-650 °F, limited abrasion resistance relatively inexpensive cutting tools (drills, taps, reamers, broaches) low-temperature machining Important Machining Factors of Carbon Steels Production

It Increases the toughness and has no adverse effect on machinability. Chromium (Cr) is Present in most low alloy steels with a weight content of 0. 5
SCM440 is medium carbon chromium molybdenum alloy steel, which is an alloy steel containing chromium and molybdenum. It has the advantages of stable composition, low harmful elements, high steel purity, small decarburization layer and few surface defects. It is easy to be spheroidized and has low cold cracking rate. Machining of Carbon and Alloy Steels Machining This article describes the influence of steel chemical compositions and microstructure on machining processes. It discusses the various microstructural phases of standard carbon and alloy steels, which influence machinability. The article reviews the expected response of several traditional machining operations, such as turning, drilling
Description:Universal 80S-D2 is a manganese, molybdenum, silicon low alloy steel wire producing weld deposits of unusually high strength, ductility and impact properties. This alloy was developed for the welding of medium carbon and sulfur bearing free machining steels. When. Applications:Other. Medium Carbon Steel Supply from Taiwan - JFS Steel steel Medium carbon steel has a certain degree of plasticity, toughness, strength, and good machinability after quenching as well as cutting performance but has poor welding performance. Strength and hardness higher than low carbon steel, plasticity and toughness lower than low carbon steel. Hot-rolled and cold-drawn materials can be used without heat treatment, and
A high carbon, chromium containing, low alloy steel. A moderately deep hardening alloy with high resistance to wear, medium toughness and low resistance to softening at high temperatures. 8620:General purpose alloy. It is the most widely used of all case hardening alloys. 86L20:Case hardening steel that is supported by a tough, ductile core. Steel, Carbon Steel and Stainless Steel Grades Available Low Carbon Steels/Mild Steels contain up to 0.3% carbon; Medium Carbon Steels contain 0.3-0.6% carbon; High Carbon Steels contain more than 0.6% carbon . No carbon steel can contain more than 2.1% carbon by weight. Sometimes carbon steels can be categorized as alloy steels, but technically they should fall into two separate groups.
Alloy Steel Machining Services Alloy steels include both low carbon & medium carbon steels. Steel alloys such as 8620 (low carbon) and 4140 & 4340 (medium carbon) offer a better combination of strength, toughness, and hardness. Alloy steel machining can be more difficult to machine, so choose your steel machining company with care!
