The difference between application of 20# steel and Q345 steel. 20# steel is mainly used for making parts, which can be heat treated; Q345 steel is mainly used for making engineering structural parts, which is usually not heat treated. Q345 steel does not emphasize the composition, but its yield strength must be above 345mpa. Because the composition A514 grade A alloy steel plate is not fixed, Q345 steel is difficult to heat treatment (the temperature and time control of heat treatment are related to the composition, and different components use different processes).
At the same time, the company operates a variety of products of related iron and A514 grade A alloy steel plate steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained A514 grade A alloy steel plate ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
At present, there are many cutting methods for A514 grade A alloy steel plate steel plate cutting, such as common flame cutting, plasma cutting and laser cutting. Different cutting methods correspond to different cutting tools and cutting equipment. Therefore, based on this point, we can know that the answer to this question is yes, that is, there are many tools and equipment involved in A514 grade A alloy steel plate steel plate cutting, You can choose according to the cutting mode.
A small amount of Nb is sufficient to obtain excellent comprehensive properties of A514 grade A alloy steel plate etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
