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.

AISI 4140 steel 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.

Stainless Steel 317L Square Bars are magnetic, and offer increased tensile and yield strength over the other categories.SS 317L Round Bars, which may contain molybdenum contents of up to 5 % & nitrogen of up to 0.4 %. When specifying stainless steel chemistry, Stainless Steel 317L Flat Bars is important to reference the appropriate ASTM standard and the UNS (Unified Numbering System) number associated with the specific alloy or grade. UNS numbers of Stainless Steel 317L Threaded Bars are internationally recognized specific chemistry requirements. If common names such as AISI numbers are referenced, the UNS number of Stainless Steel 317L Hollow Bars should also be used to avoid confusion. The many unique values provided by Stainless Steel 317L Hexagonal Bars make it a powerful candidate in materials selection.

The bright, easily maintained surface of Stainless Steel 317L Triangular Bars provides a modern and attractive appearance. Engineers and designers often underestimate or overlook these values of Stainless Steel 317L Bars because of what is viewed as the higher initial cost of stainless steel. However, over the total life of a project, Stainless Steel 317L Rods is often the best value option. 317L Stainless Steel Round Bars resist corrosion in atmospheric and pure water environments, while high – alloyed grades can resist corrosion in most acids, alkaline solutions, and chlorine bearing environments, properties which are utilized in process plants.

Grade 430 is a ferritic, straight chromium, non-hard enable grade, combining good corrosion resistance and formability characteristics with useful mechanical properties. Its ability to resist nitric acid attack permits its use in specific chemical applications but automotive trim and appliance components represents its largest fields of application.

Grade 430F is the free-machining version of this grade, available in bar form for use in automatic screw machines. Grade 434 is the molybdenum bearing version of Grade 430 and has the same useful combination of properties. Its molybdenum addition improves corrosion resistance.

These properties for 430 are specified for flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as forgings and bar in their respective specifications. Properties of Grade 430F are specified for bar in ASTM A582.

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
