How to improve toughness of density of SPA-C

Our company's density of SPA-C power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the density of SPA-C utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

S355NL normalized steel has different impact energy requirement for impact tests at different temperature environment. S355NL plate shall be done impacting test in longitudinal direction under -50℃ with the minimum energy 27J. When customers request done charpy_V notch test under -20℃,then the impacting energy shall be above 47J. For the transverse direction,the engery shall be above 16J under the temperature -50℃. The density of SPA-C, steel Grade S355NL making process shall according to EN10025-1.

The surface hardness of NM400 wear-resistant steel plate usually reaches 360-450HB, and the steel has a high mechanical strength. Its mechanical properties are three to five times that of ordinary low alloy steel plate. NM400 wear-resistant steel plate has excellent mechanical properties and good wear resistance, and can adapt to various mining conditions under different working conditions. NM400 steel can significantly improve the wear resistance of mechanical components, improve the service life of machinery, and reduce production costs.

The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as density of SPA-C. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.

Alloy steel product density of SPA-C size and stock (mm): 25*2200*9250, 25*2200*9200, 30*2200*10450, 35*2200*11050, 35*2000*11400, 75*2200*6100,,35*2200*9100, 50*2200*10000, 75*2200*6000, 35*2200*9300, 43*2100*12000, 70*2200*6500, 60*2200*10000, 60*2200*7450, 40*2200*11050, 43*2100*12000, 65*2200*6800, 90*2200*10000, 70*2200*10000, 110*2200*10000, 130*2200*10000, 150*2200*10000.

BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the density of SPA-C hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.
