What is the difference between Q235 steel and Q345 steel? First, strength difference: the lower limit of yield strength of Q235 steel is 235MPA, and the lower limit of yield strength of Q345 steel is 345MPA (Q means "Qu" in Chinese characters, and the later value represents the lower limit of yield strength). Second, the chemical difference: the alloy content of Q235 steel and Q345 steel is different, Q235 steel is ordinary carbon steel, while Q345 steel is low alloy steel q355gnh steel for sale.

We have many kinds of boiler and pressure vessel steel materials, including ASTM, ASME, DIN, JIS, en, GB and other multinational standards, dozens of steel grades. Customers have a wide range of options. At the same time, we have obvious advantages in wide and thick plates. The widest boiler plate can be more than 5 meters. The q355gnh steel for sale and pressure vessel steel price is also competitive, and there is a professional team to serve you.

Corrosion resistance mechanism of q355gnh steel for sale, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.
