Q370qDNH steel plate atmospheric corrosion resistance steel grade: Q—The first letter of the Chinese pinyin of "qu" for the yield strength of steel used in bridges; 370-a specified value of small yield strength, unit MPa; q-the first letter of the Chinese pinyin of the word "bridge" for bridge steel; D—The quality level is D level; N——The first letter of the Chinese phonetic alphabet of the word "Nei"; H——The first letter of Pinyin of "hou"; Q370qDNH steel standard: GB/T 714-2015.
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, A633 Grade A structural steel, 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.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of A633 Grade A structural steel etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in A633 Grade A structural steel etc. steel is strictly controlled.
