What is the material 30MnB5 element chemical composition
Based on the main material 30MnB5 business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel material 30MnB5 products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
19Mn6 steel is common carbon manganese low alloy steel produced according to DIN17155. 19Mn6 steel has strict control over harmful elements sulfur and phosphorus in chemical composition. The mass fraction of sulfur and phosphorus in the steel material 30MnB5 is not more than 0.02%. In addition, vacuum degassing technology is used in smelting, which greatly reduces the gas content in the 19Mn6 steel. 19Mn6 steel has good comprehensive mechanical properties, welding properties and technological properties.
What is the specific use of material 30MnB5, 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.
Chromium element (Cr element) can improve the strength and hardness of material 30MnB5, 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.
material 30MnB5 product plate specification range:Thickness 3-150mmWidth 1500-4020mmLength 4000mm-17000mmHeat treatment: annealing, or normalizing and tempering
