Main product: low-temperature boilerplate, pressure vessel plate, JIS carbon steel SM490B CS plate high-strength plate, Q245R, Q345R grade, Q420C, Q690C, Q690D, Q345R steel plate, A516 Gr 70, A572 Grade 50 equivalent. The company's long-term and stable cooperation relationship with major steel mills ensures that the company provides excellent products and high-quality services to new and old customers, and strives to build a first-class marketing system in the industry.

16MnDR steel plate is suitable for low temperature pressure vessels manufacturing. Grade 16Mn- indicates that the content of manganese (Mn) in the steel plate is relatively high, about 1% -1.6%, D- indicates low temperature, R- indicates pressure vessel. (Normally, when the content of a certain chemical element in steel is high, it needs to be marked in the material, for example, 1.6% manganese is written as 16Mn; certain elements such as Cr and Mo are higher, written as Cr1, Mo1, Such as 12Cr2Mo1R.) The normal delivery status is normalized delivery (Normalized).

Different from JIS carbon steel SM490B CS plate, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.

EN10083-3 42CrMo4 steel plate is a common chromium-molybdenum steel that usually used after quenched and tempered. JIS carbon steel SM490B CS plate, EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness. EN10083-3 42CrMo4 steel plate has better performance than 34CrMo4 steel due to the carbon and chromium content is higher.
