Three common cutting methods of ASTM A572 carbon steel plate sheet cutting

The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of ASTM A572 carbon steel plate sheet cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.

BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our ASTM A572 carbon steel plate sheet office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase ASTM A572 carbon steel plate sheet 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for ASTM A572 carbon steel plate sheet.
