ASTM A709 low alloy steel sheet and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields. The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate. Therefore, the medium and heavy plates manufacturers and users attach great importance to it. The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plates.
Based on the main ASTM A709 low alloy steel sheet business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel ASTM A709 low alloy steel sheet products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
The steel plate cutting and processing instructions are as follows: steel plate cutting and steel plate cutting processing, as well as ASTM A709 low alloy steel sheet steel plate zero cutting processing. There are semi-automatic flame cutting, fully automatic CNC cutting, laser cutting and water cutting. The thickness range of steel plate that can be cut is 20650mm. In terms of ASTM A709 low alloy steel sheet steel plate cutting types, there are Q235B common plate, Q345B low alloy plate and 45 carbon bonded plate.
Composition characteristics of Q420 alloy steel plate: 1.Low carbon: Due to the high requirements for toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%. 2. Add manganese-based alloy elements. 3. Add auxiliary elements such as niobium, titanium or vanadium, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the Q420 alloy steel, ASTM A709 low alloy steel sheet.
We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
