S420ML grade steel,
Q420q material is a kind of structural steel plate for bridges, and there are three quality levels Q420qD, Q420qE and Q420qF. When the Q420q plate is required to have the performance in the thickness direction, the symbols Z15, Z25, Z35 representing the performance level in the thickness direction are added after the above-mentioned grades. Namely Q420qDZ15, Q420qDZ25, Q420qDZ35, Q420qEZ15, Q420qEZ25, Q420qEZ35, Q420qFZ15, Q420qFZ25, Q420qFZ35.

S420ML grade steel,Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. S420ML grade steel, Q420 steel has high comprehensive mechanical properties Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states The quality grades are C, D, E Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load,S420ML grade steel.

we also provide the welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.
