Carbon steel is a steel with carbon content up to 2.1% by weight.

Steel is classified to be carbon steel when: no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect; the specified minimum for copper does not exceed 0.40 percent; or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60.

The term "carbon steel" may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels.

As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however, it becomes less ductile. Regardless of the heat treatment, a higher carbon content reduces weldability. In carbon steels, the higher carbon content lowers the melting point.

Types of Carbon Steel:

Low Carbon Steel

Mild Steel

High carbon Steel

Applications:

Fasteners and Bolts

Shafts, spindles, pins, rods, sprocket assemblies

Crankshafts, couplings, and cold headed parts.

Axles, Bolts, studs, and machine parts.

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
Press plates
Petrochemical equipment
Firearms production
Gate valves
Mining machinery
Distillation trays.

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

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.

“Cold Roll” is the nickname for steel that is produced in the “cold rolling” method, processed at close to normal room temperatures. Cold Roll is limited to a few shapes but comes in many finishes and offers superior strength and machinability. We provide cold rolled bar in Stainless Steel grades such as 303 Stainless Steel, 304 Stainless Steel, 304L Stainless Steel, 304H Stainless Steel, 316 Stainless Steel, 316L Stainless Steel, 316H Stainless Steel, 316Ti Stainless Steel, 321 Stainless Steel, 321H Stainless Steel, 416 Stainless Steel, 347 Stainless Steel, , 310 Stainless Steel, 310S Stainless Steel etc. Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. The term Cold Rolled is mistakenly used on all products, when actually the product name refers to the rolling of flat rolled sheet and coil products. When referring to bar products, the term used is “cold finishing”, which usually consists of cold drawing and/or turning, grinding and polishing.

Benefits:
Cold drawing increases the yield and tensile strengths, often eliminating further costly thermal treatments.
Turning gets rid of surface imperfections.
Grinding narrows the original size tolerance range.
Polishing improves surface finish.
All cold products provide a superior surface finish, and are superior in tolerance, concentricity, and straightness when compared to hot rolled.
