Common steel properties and applications

   Nowadays, steel is used more and more widely. They have a variety of varieties. As far as I know, we can distinguish steel according to the shape of the section. They mainly divided into four categories. Mainly refers to carbon steel, alloy steel, stainless steel and tool steel. Now, let me tell you about the characteristics and fields of application of several common sheets of steel.
   
AISI 1045 steel is one of carbon steel. It is a medium tensile low hardenability carbon steel generally in the black hot rolled or occasionally in the normalized condition. Characterized by fairly good strength and impact properties, plus good machinability and reasonable weldability in the hot rolled or normalized condition. Typical applications are: Axles Various, Bolts, Connecting Rods, Hydraulic Clamps and Rams, Pin Various, Rolls Various, Studs, Shafts, Spindles, etc.
   
AISI 4140 alloy structural steel is one of alloy steel. It belongs to medium hardenability steel with Excellent fatigue resistance, good processability and small deformation when processing. After heat treatment,alloy steel has good intensity and Nice synthetic mechanical properties. Alloy steel used in the manufacture of high strength forgings,such as Locomotive traction with the big gear,supercharger Transmission gears,rear axle,huge load of connecting rod and spring clips,also available at 2000 meters deep of oil drill pipe joints and fishing tools,can also be used for bending machine mould,etc.
   
AISI 316 stainless steel is austenitic stainless steel. Due to the addition of the Mo element, it has a great improvement in corrosion resistance and high-temperature strength. It can withstand high temperatures up to 1200-1300 degrees and can be used under harsh conditions. The main uses are heat exchangers for pulp and paper equipment, dyeing equipment, film processing equipment, pipes, and materials for exterior use in coastal areas. Also used in the field of solenoid valves in 2013, mainly used for housings, clamps, spheres, valve bodies, valve seats, nuts, valve stems, etc.
   
H13 mold steel is hot work tool steels. It has good tempering resistance, high temperature wears resistance, good quenching and heat resistance impact resistance, high strength, high toughness, good Thermal cracking resistance. It can be nitrided to increase wear resistance. It is used for making extrusion mold and casting mold of aluminum-magnesium alloy, zinc alloy and copper alloy. It is also can be used for making a hot pressing mold and so on.
DIN 1.2738 plastic mold steel with excellent polishability properties, good wear resistance, high hardness, good machinability, suitable for surface treatment, can be processed by nitride. It suitable for large injection and compression mold for plastic processing 400mm thickness such as TV chassis, copiers, bumpers, shock absorbers, garbage and the dashboards, die casting.

The role of alloying elements (Aluminum(Al), Boron(B), Copper(Cu), Sulfur(S))

Image
Although the alloying elements are very small, they can determine the type and characteristics of the steel that people produce. It can make a difference between steel and steel. Then let's explore the following elements. (1)Aluminum(Al) Aluminum is mainly used to deoxidize and refine grains. In the nitriding steel, a hard and corrosion resistant nitriding a layer is formed. Aluminum can suppress the aging of low carbon steel and improve the toughness of steel at a low temperatures. When the aluminum content is high, the oxidation resistance of the steel and the corrosion resistance in the oxidizing acid and the H2S gas can be improved. And it can improve the electrical and magnetic properties of the steel. Aluminum has a large solid solution strengthening effect in steel, which improve the wear resistance, fatigue strength and core mechanical properties of carburized steel. In the difficult alloy, aluminum and nickel form a compound. Thereby improving the smelting strength. T...

The role of alloying elements(Chromium(Cr), Nickel(Ni), Molybdenum(Mo))

In order to make better and improve certain properties of steel and to achieve certain special properties. The elements that are intentionally added during the smelting process are called alloying elements. Commonly used alloying elements are chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, silicon, manganese, aluminum, copper, boron, rare earth, etc. Phosphorus, sulfur, nitrogen, etc. also act as alloys in some cases. Let us talk about some of them. (1)Chromium(Cr) Chromium can increase the hardenability of steel and has a secondary hardening effect, which can improve the hardness and wear resistance of carbon steel, so that the steel does not become brittle. When the content exceeds 12%, the steel has good high-temperature oxidation resistance and oxidation resistance, and also increases the thermal strength of the steel. Chromium is the main alloying element of stainless steel acid-resistant steel and heat-resistant steel. Chromium can incr...

The role of alloying elements (Cobalt(Co), Manganese(Mn), Phosphorus(P), Rare earth (Re))

Image
It is precise because of the variety of elements, and the existence of various forms. Therefore, their role in steel is also variable. Let us finally explore the remaining alloying elements. (1)Cobalt(Co) Cobalt often uses in the special steel and alloy. The cobalt containing high-speed steel has high high-temperature hardness. Simultaneous addition of molybdenum to maraging steel. It can get an ultra high hardness and good overall mechanical properties. In addition, cobalt is also an important alloying element in heat-strength steel and magnetic materials. Cobalt can reduce hardenability of steel. Therefore, adding cobalt alone to carbon steel will reduce the overall mechanical properties after quenching and tempering. Cobalt can strengthen ferrite. Adding to carbon steel can improve the hardness of steel, yield point and tensile strength under an annealed or normalized state. However, it has an adverse effect on the elongation and the reduction of the area, and the impact toughn...
