Tool Steel-D2 steel is an air hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion resistant properties. It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition. D2 steel shows little distortion on correct hardening. D2 steel’s high chromium content gives it mild corrosion resisting properties in the hardened condition.

Typical applications for D2 Steel:

Stamping or Forming Dies
Punches
Forming Rolls
Knives, slitters, shear blades
Tools
Scrap choppers
Tyre shredders

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.

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.

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.

420 Round Bar Martensitic stainless steels are designed for high hardness, and other properties are compromised to an extent. Their functional operating temperature range is restricted by their loss of ductility at sub-zero temperatures, and loss of strength by over-tempering at high temperatures.

Alloy designations of 1.4021 is similar, but it may not be a direct equivalent to: 420, UNS42000, 1.4021, 1.4024, 1.4028, 1.4029, 1.4030, and 1.4034. It is supplied in the form of a bar.

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.
