When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials ASTM A514 QT steel plate. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
Hot rolling and cold rolling are all the processes of forming steel plates or profiles, which have a great influence on the structure and properties of steel. The rolling of steel is mainly hot rolling, and cold rolling is usually used to produce small size steel and thin plate. With the development of new technologies such as the precision of hot rolling size, shape and surface quality and the continuous emergence of new products, ASTM A514 QT steel plate, hot rolled steel strip and steel plate are widely used and have more and more competitive strength in the market.
ASTM A514 QT steel plate annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of ASTM A514 QT steel plate annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. ASTM A514 QT steel plate annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the ASTM A514 QT steel plate steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the ASTM A514 QT steel plate steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the ASTM A514 QT steel plate steel sheet on the truck Good luck.
We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about ASTM A514 QT steel plate pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.
