Alloy Steel Tube Has Low Temperature Resistance Characteristics
Jul 14, 2017

The alloy steel pipe refers to the addition of silicon and manganese as alloying elements or deoxidation elements, it also contains other alloying elements (such as chromium, nickel, molybdenum, vanadium, titanium, copper, tungsten, aluminum, cobalt, niobium, zirconium, and other elements), and some are also contained in certain non-metallic elements (such as boron, nitrogen, etc.) of steel. Because of the different kinds and quantities of alloying elements in alloy steel tubes, and taking appropriate technological measures, Alloy Steel Pipe and Tube they can have high strength, toughness, hardenability, abrasion resistance, corrosion resistance, low temperature resistance, heat resistance, heat strength, red hard and so on.

The main alloying elements of alloy steel tubes are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth and so on. of which vanadium, titanium, niobium, zirconium in the steel is strong carbide forming elements, as long as there is enough carbon, under appropriate conditions, can form their own carbide, when the lack of carbon or at high temperature conditions, the atom state into solid solution; manganese, chromium, tungsten, molybdenum for the formation of carbide elements, Alloy Steel Pipe and Tube part of the atom into the solid solution, the other part of the formation of replacement alloy cementite, aluminum, copper, nickel, cobalt, silicon and so on is not formed carbide elements, generally in the atomic state in solid solution.

There are a wide variety of alloy steel tubes, which need to be classified for easy production, use and scientific research.

(1) Classification by use, can be broadly divided into: structural steel, mechanical structural steel (in addition to alloy structural steel), but also include alloy spring steel and bearing steel, tool steel (including mold steel and high-speed tool steel) as well as special steel (stainless steel, heat-resistant, leather-free steel, etc.).

(2) According to the total content of alloying elements can be divided into: Low alloy steel pipe (under 5%), Medium alloy steel pipe ($number) and high alloy steel pipe (more than 10%).

(3) According to the main elements of the classification, Alloy Steel Pipe and Tube there are chromium steel, nickel, molybdenum steel, nickel, cr-ni-mo steels.

(4) According to the metallographic structure of alloy steel pipe can be divided into: ferrite Steel, pearlite Steel, bainite Steel, martensitic steel, austenitic steel, and eutectoid and eutectoid, etc.

Alloy steel pipes are widely used in the fields of construction, machinery and tools because of their extensive use. Everyone in the purchase of furniture building materials such as kitchen knives, Alloy Steel Pipe and Tube you can first understand the characteristics of alloy steel pipe, before you can understand the characteristics of the product.
