Our ASTM A573 structural steel pipeline steel has once again helped the construction of the China-Russia East Line Natural Gas Pipeline. During 2017 - 2018, the company successively supplied more than 10,000 tons of high-grade pipeline steel materials for the northern section of the Sino-Russian Eastern Gas Pipeline project, helping the northern section of the ASTM A573 structural steel project to be successfully completed. Now we reload the task and will provide API 5L X80 high-grade pipeline steel for the middle section of the China-Russia Eastern Gas Pipeline project.

Spring steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. ASTM A573 structural steel, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. Spring steel has hot rolled steel, cold drawn steel, cold rolled steel strip and so on. How much a ton of spring steel is related to the grade of spring steel, the market situation and the manufacturer.

ASTM A573 structural steel, Wear-resistant steel plates are easy to overheat, so pay attention to heating temperature and holding time. It is recommended to heat up to 820 degrees for proper insulation. Tempering temperature: 320 degrees, sufficient time. Hardness: 45-48HRC. Good performance. Salt bath NaCl:BaCl=3:7 can be heated at a temperature of 820, time is 30 seconds/mm (mm refers to the effective thickness of the part), oil cooling. Tempering temperature is 280, air furnace time is 2 hours, and nitrate furnace time is 30 minutes.
