Round Bar

An unalloyed medium carbon steel. En8 is a medium strength steel, good tensile strength. Suitable for shafts, stressed pins, studs, keys etc. En8 carbon steel is also readily machinable in any condition. En8 steels are generally used in the as supplied untreated condition. But En8 steels can be further surface-hardened by induction processes, producing components with enhanced wear resistance. Steel En8 materials in its heat-treated forms possesses good homogenous metallurgical structures, giving consistent machining properties. En8 steel grade belongs to the standard of BS 970-1955, which is a standard for wrought steel for mechanical and allied engineering purpose. In BS 970 standards.

En8 Steel Round Bar: 8mm-1600mm

En8 Steel Cold Drawn Bar: 5mm-70mm

En8 Carbon Steel Flat & Plate: 10-1500mm x 200-3000mm

En8 steel material is suitable for the all general engineering applications requiring a higher strength than mild steel such as:

general-purpose axles.
shafts,
gears,
bolts and studs.
spindles,
automotive and general engineering components,
other general engineering parts etc.

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:

Alloy Steel
Carbon Steel
Stainless steel
Titanium
Nickel
Aluminium

Applications:

Automotive Truck
Agricultural Machinery & Equipment’s

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.
Grade 6150 – Chromium Vanadium Steel.
Grade 8620 – HSLA -Nickel-Chromium-Molybdenum Steel.

Applications:

Shaft
Crankshaft
Bolt
Nut
Gear
Slide
Steel Collet

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.
Good corrosion resistance to low concentrations of mild organic and mineral acids.
Oxidation resistant through 1500°F intermittently, 1200°F continuously.
Corrosion resistant.
 
Applications:
Applications requiring moderate corrosion resistance and high mechanical properties are ideal for Alloy 410. Examples of applications that frequently used Alloy 410 include:
 
Cutlery
Steam and gas turbine blades
Kitchen utensils
Bolts, nuts, screws
Pump and valve parts and shafts
Mine ladder rugs
Dental and surgical instruments
Nozzles
Hardened steel balls and seats for oil well pumps

Stainless Steel Threaded Rod is a continuous length of bar that is threaded so a nut can be screwed on from either end. All thread, Running Thread, Threaded Bar, Studding, Studs or Stainless-Steel Threaded Rod is usually Class 50 by default, but is often made to Class 70 strength in most sizes. Class 50, 70 or Class 80 refers to its Tensile Strength; with Class 50 meaning a Tensile Strength of 500MPA. Class 70 or 80 is available in various sizes. Threaded Rods Fasteners are used to create non-permanent joints i.e. joints that can be removed or dismantled without damaging the joining components. There are three major steel Threaded Rods Fasteners used in industries: Stainless steel, Carbon steel & Alloy steel. The major grade used in Stainless Steel Threaded Rods are: - 200 series, 300 series, and 400 series.

Titanium, Aluminum & other various alloys are also common materials for construction In many cases, special coatings or plating may be applied to Steel Threaded Rods Fasteners to improve their performance characteristics by, for example, Enhancing Corrosion Resistance. Common coatings/plating’s include Zinc, Chrome & Hot Dip Galvanizing (HDG).

A threaded rod is a type of a fastening bar which is relatively long & threaded on both the ends of the rod. The threading on the Stainless-Steel ACME threaded rod may be extended up to the entire length of the rod. This is also known as a stud.

Generally produced from cold-rolled stainless-steel grades. the cost of this ss threaded rod is low. 

Fully Threaded Stud Bolts – The body of these threaded rods are fully covered by threads and hence are utilized for its engagement to the mating of nuts or similar fasteners.

Tap End Stud Bolts – the extreme ends of the body of the Tap End Stud Bolts are threaded with an unequal thread engagement length.

Double End Stud Bolts – These rods have equal thread length at both ends.

Owing to the years of industrial experience, we have been able to serve our valued clients with a wide range of Monel Rods.
