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.

Aircraft Engine Mounts and Welded Tubing Applications.

Gears, Aircraft landing gear axles, and Shafts for power transmissions.

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.

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.

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.

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.

Molybdenum Rods

Molybdenum is silvery-white metal that is highly resistant to corrosion and ductile in nature. It is having the highest melting points of all the pure elements, only the tungsten and tantalum having higher melting points. The alloy is micronutrient that for life is essential. It as a transport metal, molybdenum is easily forming compounds that easily form compounds with other compounds. Molybdenum is comprising of 1.2 parts per million of the earth crust by the weight. The tests are also conducted to assure the quality of rods manufacturing. The tests done are namely positive material identification test, chemical test, intergranular corrosion test, hardness test, mechanical test, flattening/flaring test etc.
