How about the inventory of A573 Grade 70 rolled structural steel in China at present

At the same time of doing well in A573 Grade 70 rolled structural steel production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A573 Grade 70 rolled structural steel technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

The carbon tool steel thick plate is made of carbon tool steel and is made by hot rolling. This carbon tool steel has good cold and hot processing performance, high hardness and plastic resistance, low production cost and wide range of uses. A573 Grade 70 rolled structural steel, Carbon tool steel is usually delivered in an annealed or high temperature tempered state. It is mainly used to manufacture cutting tools, measuring tools and molds with low cutting speed, simple shape and low precision. The thickness of the steel plate is 4.5-25mm, and the width and length comply with GB709 regulations.

NM400 wear resistant steel plate has a very high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; it can improve the wear resistance of mechanical related parts; therefore improve the service life of machinery; reduce production costs. The surface hardness of the product A573 Grade 70 rolled structural steel is usually Reached 360 - 450HB. NM400 wear resistant steel plate is used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.
