Welcome to BBN High Strength Steels Factory
Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for S690 steel equivalent grades various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several S690 steel equivalent grades after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel S690 steel equivalent grades can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.
The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the S690 steel equivalent grades steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the S690 steel equivalent grades steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.
20 to 26mm thick S690 steel equivalent grades product BBN steel supply: 20*3000*5000, 20.5*2370*7000, 21*1960*7950, 22*1800*8000, 22*1500*6000, 22*1500*6050, 22.5*1680*8450, 22*1300*4000, 22*2600*9000, 22*1800*9000, 22.5*2560*7150, 23.5*2560*7150, 25*1460*4000, 23*3000*11980, 23*2480*8450, 23*2650*6000, 24*1560*6200, 25.5*2330*8300, 23*3000*12000, 23.5*2080*8100, 23*2650*6550, 26*3010*8100.
