S275JR steel plate Mn element content

Q370R Pressure Vessel Steel: Steel used to manufacture pressure vessels in petrochemical, gas separation, gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The commonly used steels S275JR steel plate are mainly low-alloy high-strength steel and carbon steel. Q370R implements the domestic standard GB713-2008.Our company has S275JR steel plate strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply S275JR steel plate deep processing service for products S275JR steel plate like cutting, drilling, bending, welding and grinding.TMCP process is an indispensable technology for our production of low alloy high strength wide and S275JR steel plate thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy S275JR steel plate and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.The amount of Vanadium in steel material is generally between 0.04% and 0.12%. The role of Vanadium is to affect the microstructure and properties of steel material. It mainly precipitates in the ferrite at the austenite grain boundary, and can inhibit the recrystallization of austenite and prevent the crystal during rolling. The grains grow, which refines the ferrite grains and improves the strength and toughness of S275JR steel plate etc. steel material.Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.
