What is the main function of S355nl VS S355ML

The company attaches great importance to systematic management, and has passed the S355nl VS S355ML ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on S355nl VS S355ML quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

Q345E steel is low-alloy high-strength steel with good low-temperature impact properties. The grade of Q345E steel is composed of three parts: Chinese phonetic alphabet representing yield strength, yield strength value and quality grade symbol. Where: Q is the yield strength; 345 is the yield strength value in MPa; E is the grade (passing the - 40 degree impact test). S355nl VS S355ML, Q345E steel is mainly used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, power stations, workshops, low-temperature pressure vessels, etc.

Different form S355nl VS S355ML, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.

The hardness and impact toughness of precipitation-strengthened wear plates, S355nl VS S355ML are also improved. For example, the hardness of the wear-resistant plate after precipitation strengthening is 230-300 HBW, and the impact toughness is 140-180. More importantly, the improvement of the above indicators does not bring about a significant decrease in plasticity. The performance of the wear-resistant plate after water quenching at 1100℃, first holding at different temperatures in the middle temperature zone, and then water quenching at 970℃. With the increase of the holding temperature in the middle temperature zone and the extension of the holding time, the number of carbides in the steel increases, and the precipitation strengthening effect increases, resulting in an increase in hardness.

EN10083-3 42CrMo4 steel plate is a common chromium-molybdenum steel that usually used after quenched and tempered. S355nl VS S355ML, 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.
