Determination of yield point and yield strength of hardox 400 steel application

SM400A/B/C steel structural quality carbon steel profiles, HARDOX 400 steel application plates and bars used for riveting, bolting or welding of bridges and buildings and general structural purposes.

We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of HARDOX 400 steel application boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with HARDOX 400 steel application high-end steels and competitive price.

The HARDOX 400 steel application steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the HARDOX 400 steel application internal quality of the steel.

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of HARDOX 400 steel application etc. steel material.

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.
