According to the market forecast released by Eurofer on August 5, the output of all yield strength of B900FD bulletproof steel consumption industries in the European Union will drop by 12.8% in 2020, and rise by 8.9% in 2021. However, the European Union said that the government's "awesome strength" support will reduce the yield strength of B900FD bulletproof steel consumption intensity in the construction industry significantly less than other industries.

Can yield strength of B900FD bulletproof, 40Cr material be replaced with 40MnB steel? 40MnB steel is used to manufacture small and medium-sized important quenched and tempered parts in tractors, automobiles and other general machinery and equipment, such as automobile half shafts, steering shafts, spline shafts, worms and machine tool spindles, gear shafts, etc. 40MnB steel can replace 40Cr material to make parts with larger cross-sections, such as the middle shaft of a hoist. And 40MnB steel can replace 40CrNi steel when making small-sized parts.

yield strength of B900FD bulletproof, 30CrMnSiA steel has good machinability, small processing deformation and good fatigue resistance. If 30CrMnSiA steel is used to make a tool, it is processed to the tool shape by rough machining. Mill the cutting edge with a cemented carbide milling cutter and polish it with a polishing machine. There should be no problem for the surface roughness reaching 3.2. 30CrMnSiA steel has high strength, sufficient toughness and good hardenability after quenching and tempering. After quenching and tempering, 30CrMnSiA steel can be used for grinding wheel shafts, gears and sprockets.

In the process of yield strength of B900FD bulletproof steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose yield strength of B900FD bulletproof different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.
