Sample Ramor 300 steel plate for helmet material grade

ASTM A516 is also known as ASME SA516. The A516 / SA516 standard specification for pressure vessel plates, carbon steel, for moderate- and lower-temperature service. A grade Ramor 300 steel plate for helmet intended primarily for service in welded pressure vessels where improved notch toughness is required, and is normally found in moderate and lower temperature applications. All plates over 1-1/2″ Thick are required to be normalized. A516 Grade 70 steel is the most popular pressure vessel grade of steel plate in the industry.

With high-quality Ramor 300 steel plate for helmet steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our Ramor 300 steel plate for helmet steel market and improved the control of steel plate production quality.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched Ramor 300 steel plate for helmet increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of Ramor 300 steel plate for helmet during tempering, while tempering determines the performance and life of the workpiece.

Ramor 300 steel plate for helmet, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
