The alloy steel with a total amount of alloy is less than 5%.Low -alloy steel is relative to carbon steel. On the basis of carbon steel, in order to improve one or several properties of steel, it is interested in adding one or more alloy elements to the steel.When the normal content of carbon steel has the general content, this steel is called alloy steel.When the total amount of alloys is lower than 5%, it is called low alloy steel.The alloy content is between 5-10%?
Low -alloy steel price
The price of low alloy steel is mainly affected by its name, specifications, and manufacturers.In addition, the differences in the material of low alloy steel, the number of starting batch, the time point, and other factors can also affect the price to a certain extent.In terms of batches, some low -alloy steels are purchased, and there will be discounts in terms of price.Low -alloy steel price introduction (unit: yuan) (1) low alloy round steel, product name: fitting steel, material: 16mn, Dongguan mayor An Shenyou metal material operation department ￥ 12.00 (starting batch ≥1 kg) (2) lowMetal steel, product name: Following steel, material: 45CRNIMOV, specifications: round steel diameter 10-350, steel plate thickness 3-300, Dongguan Minglong mold steel operation department ￥ 18.00 (start batch ≥5 kg) (3) low alloy low alloyRound Steel, Product Name: Low Alloy Round Steel, Material: Q345C, Liaocheng Aoyao Metal Material Co., Ltd. ￥ 3350.00 (specification: φ110) ￥ 3360.00 (specification: φ20) ￥ 3380.00 (specification: φ160) ￥ 3390.00 (specification: φ200)
Low alloy steel classification
The classification of low alloy steel includes general quality low alloy steel, high -quality low -alloy steel and special quality low -alloy steel.I. Low -alloy steel: First of all, Xiaobian introduces you general quality low alloy steel.This general quality low alloy steel means that there is no special requirements on this issue during the production process. At the same time, its alloy content is relatively low, and heat treatment does not specify.The maximum value of sulfur and phosphorus in general quality of low alloy steel is greater than equal to 0.045%.The minimum value of its tensile strength is less than 690MPa, the minimum elongation rate is less than 26%, the minimum value of the yield point or yield strength is less than 360MPa, the minimum value of the impact is less than 27J, and the minimum diameter of the bending heart diameterGreat or equal to 2 × Sample thickness.
Low alloy steel standard
1. The beginning of the two numbers at the beginning of the steel number indicates the average content of carbon, and the order of order is one in 10,000.For example, 40Cr means that the average carbon content in steel is 40 percent.2. In the steel number, the alloy element is generally considered as a magnitude of level. When the mass score of the alloy is less than 1.5%, it can not indicate the content, but only indicates the alloy element.In order to avoid confusion between different elements, it can also be marked with 1.3. Some micro -alloy elements in steel, such as rare earth elements, cymbals, boron, etc., should be indicated in the steel number regardless of the content.4. If the steel is high -quality high -quality steel, add A letters at the end of the steel to distinguish the general high -quality steel.5. Low -alloy steel with specific uses should be expressed at the end of the time to show its use.
