What is the chemical composition of q345r equivalent material?

We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of q345r equivalent material boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with q345r equivalent material high-end steels and competitive price.

The generally spoken manganese plate is low alloy high strength structural steel. This material has good weldability and can be welded by various methods. Carbon steel plate and manganese plate belong to the category of carbon structure and low-alloy structural steel. The main difference between carbon steel plate and manganese plate is that the yield strength of manganese plate is higher than that of carbon steel plate, q345r equivalent material. From the point of view of hardness, it is obvious that the hardness of manganese plate is larger than that of carbon steel plate, and the application of manganese plate is relatively wider.

High-temperature boiler steel plates such as 15CrMoR plate, 12Cr1MoVR steel plate, ASME SA387 grade 22 steel, A387 Gr 91 boiler steel, ASME SA1017 Gr 23, SA1017 Gr 911, SA1017 Gr 122 steel, q345r equivalent material, must have features of:Sufficient high temperature durability and durable plasticity;Good high temperature tissue stability;Good high temperature oxidation resistance (heat resistance);Good hot and cold processing technology (mainly refers to cold bending deformation and weldability), etc.

Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, q345r equivalent material included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.

q345r equivalent material, HP265 steel with the thickness range is 1.2-12mm. HP265 steel’s mechanical properties is include the yield strength more than 265MPa, tensile strength is 410-520MPa. The chemical composition of HP265 steel is C element content is 0.18, the Si element content is 0.10, the Mn element content is 0.80, the P element content is 0.025% max, the S element content is 0.015% max.
