What are the properties of 16MnR steel?

16MnR material is common low alloy steel, special steel for boiler and pressure vessel, and common material for boiler and pressure vessel. It has high strength and good plastic toughness. Common delivery status is hot rolled or normalized. It is a low-alloy high-strength steel with low Mn content. The performance is similar to 20G (412-540), the tensile strength is (450-655) slightly stronger, and the elongation is 19-21%, which is worse than 20G greater than 24%. The standard source is GB6654, which was gradually replaced by Q345R in 2010.

16MnR steel properties

16MnR steel is a special plate for pressure vessels with a yield strength of 340MPa. It has good comprehensive mechanical properties and technological properties. The phosphorus and sulfur contents are slightly lower than that of ordinary 16Mn steel. In addition to the increased tensile strength and elongation requirements compared with ordinary 16Mn steel, it is also required to ensure impact toughness. It is a steel plate for pressure vessels which is widely used and used in China at present.

The steel plate is divided according to the thickness, the thin steel plate is <4 mm (the thinnest is 0.2 mm), the thick steel plate is 4 ~ 60 mm, and the special thick steel plate is 60 ~ 115 mm. The width of the thin plate is 500 ~ 1500 mm; Mm. The steel grade of the thick steel plate is roughly the same as that of the thin steel plate. In all aspects of the product, in addition to bridge steel plates, boiler steel plates, automobile manufacturing steel plates, pressure vessel steel plates and multilayer high-pressure vessel steel plates, etc. are pure thick plates, some types of steel plates such as automobile beam steel plates (thickness 2.5 ~ 10 mm), patterns Steel plates (thickness 2.5 ~ 8 mm), stainless steel plates, heat-resistant steel plates and other varieties are crossed with thin plates. 2. Steel plate is divided into rolling, hot rolling and cold rolling.
