It is expected that the price of A514 Grade S steel hardness will remain weak
Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of A514 Grade S steel hardness, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the A514 Grade S steel hardness hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the A514 Grade S steel hardness steel industry.
What is the difference between Q345B steel and Q345A steel? A514 Grade S steel hardness, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
When cutting extra thick A514 Grade S steel hardness steel plates, the cutting speed should not be too fast. Many processing and production industries will encounter such problems, that is, in order to speed up the cutting of extra thick steel plates, many details will be ignored in the process of these process operations, so it is easy to produce waste parts, and some plates A514 Grade S steel hardness will crack. So when cutting extra thick steel plates, you must pay attention to the speed, which can not be too fast. Low-speed processing can effectively improve work efficiency.
