What are the advantages of high strength en10025 S420ML

Chromium element (Cr element) can improve the strength and hardness of en10025 S420ML, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

What is the specific use of en10025 S420ML, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.

en10025 S420ML, Chinese material Q235B is one of the most widely used carbon steel in the world. Some like to compare its strength with other equivalent steel grades. We need to take care that the Q235B steel strength varies with thickness. For the min. yield strength of Q235B steel plate: it is 235Mpa if thickness ≤16mm, 225 Mpa for thickness 16-40mm, 215 Mpa for thickness 40-60mm, 205 Mpa for thickness 60-100mm, 195 Mpa for thickness 100-150mm, 185 Mpa for thickness over 150mm. The tensile strength of Q235B steel plate is 375-500 Mpa.
