High tensile steel grade hardox 400 equivalent suppliers

The yield strength of A36, D36, E36 and F36 is not less than 355N/mm^2, and the HARDOX 400 equivalent tensile strength is 490~620N/mm^2. A, D, E and F respectively indicate that they can be at 0° and -20 ° respectively. Impact toughness that can be achieved at -40℃, -60 ℃.

The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The HARDOX 400 equivalent, boiler steel plate has good welding performance;The HARDOX 400 equivalent, boiler steel plate has a good microstructure, white spots and cracks are not allowed.

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 HARDOX 400 equivalent 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 HARDOX 400 equivalent 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.

Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to HARDOX 400 equivalent customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
