Round Bar

4140 Forged Round Bar - Forged Bar - Die Forged Bar - SAE 4140 - AISI 4140 - Round Bar  is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. AISI 4140 alloy steel has high ductility. It can be formed using conventional techniques in the annealed condition. It requires more pressure or force for forming because it is tougher than plain carbon steels. the mechanical properties of this steel will be affected if it is welded in the heat-treated condition, and post-weld heat treatment should be performed. After the annealing is complete, the steel is heated to a molten phase again so that it can be poured into the desired form and can either be hot worked or cold worked through rollers or other tools to reach the desired thickness. Of course, there are other special operations that can be added to this to reduce mill scale or improve mechanical properties. AISI 4140 is a low alloy steel. Low alloy steels rely on elements other than just iron and carbon to enhance their mechanical properties. In AISI 4140, additions of chromium, molybdenum, and manganese are used to increase the strength and hardenability of the steel. The additions of chromium and molybdenum are why AISI 4140 is considered a “chromoly” steel.

Forged metals tend to be harder, stronger and more durable than cast forms or machined parts. The pressure alone forms the steel into the right shape, and the metal’s response to such overwhelming force tends to align the grain. That means you get more cogent internal structure and a far greater ability to withstand warping and wearing.

There are actually four general variations of a forged bar which include: round bars, square bars, flat bars and hex bars. All Metals has the forging capabilities to produce bars from the following alloy types:

An alloy is a combination of metals or metals combined with one or more other elements. For example, combining the metallic elements gold and copper produces red gold, gold and silver becomes white gold, and silver combined with copper produces sterling silver. Elemental iron, combined with non-metallic carbon or silicon, produces alloys called steel or silicon steel. The resulting mixture forms a substance with properties that often differ from those of the pure metals, such as increased strength or hardness.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. Every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type). However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloyants include aluminium, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead, and zirconium.

The following is a range of improved properties in alloy steels (as compared to carbon steels): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and hot hardness. To achieve some of these improved properties the metal may require heat treat.

Some of these find uses in exotic and highly-demanding applications, such as in the turbine blades of jet engines, in spacecraft, and in nuclear reactors. Because of the ferromagnetic properties of iron, some steel alloys find important applications where their responses to magnetism are very important, including in electric motors and in transformers.

Types of Alloy steel:
Low Alloy Steel.
High Alloy Steel.

The most important and desired changes in alloy steel are:

Increased hardenability.
Increased corrosion resistance.
Retention of hardness and strength

The most commonly used grades of Alloy:

Grade 4140 – Chromium Molybdenum Steel.
Grade 4340 – Nickel-Chromium-Molybdenum Steel.

410 is the basic, general purpose stainless steel that is used for highly stressed parts and provides good corrosion resistance plus high strength and hardness. SS 410 contains a minimum of 11.5% chromium which is just sufficient enough to demonstrate corrosion resistance properties in mild atmospheres, steam, and many mild chemical environments. It is a general-purpose grade that is often supplied in the hardened but still machinable condition for applications where high strength and moderate heat and corrosion resistance are required. It displays maximum corrosion resistance when it’s been hardened, tempered, and then polished. Due to the hardening capabilities of this steel, other properties and the resulting performance of this material are somewhat compromised. The alloy can only effectively be used in mildly corrosive environments. It is the most widely used of the hard enable stainless steels. Heat treated 410 has mechanical properties comparable to the engineering alloy steel AISI 4130, coupled with the additional benefit of good corrosion resistance. 410 is highly resistant to atmospheric corrosion. Maximum corrosion resistance is obtained by hardening and polishing. Because 410 is an air hardening steel, it must be given a high preheat, at least 350-400°F before welding, and immediately given a full anneal before the weldment cools. Otherwise the metal will harden, and cracking is likely.
 
Features:
Readily welded by all standard methods.
Good corrosion resistance to atmospheric corrosion, potable water, and to mildly corrosive environments.
Its exposure to everyday activities (sports, food preparation) is generally satisfactory when proper cleaning is performed after exposure to use.
