raex 500 sheet material technical data
In recent years, in line with the development trend of iron and raex 500 sheet material steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which raex 500 sheet material are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
raex 500 sheet material, Alloy steel plate can be used for machining machinery and equipment. The requirement of the equipment to the steel plate is very high, so the alloy steel plate is mostly used to manufacture the mechanical equipment. The alloy steel plate can also be used as raw materials for fastening hardware. Nuts and bolts are used in a complex environment, so there must be certain requirements for strength and high temperature resistance. Otherwise, if fracture occurs, it will lead to accidents and cause a series of irreparable consequences.
Stainless steel is resistant to chemical corrosion, air or water and other weak corrosion media. Stainless steel covers ordinary stainless steel and acid resistant steel. raex 500 sheet material, Ordinary stainless steel is generally not resistant to chemical corrosion, while acid resistant steel is generally stainless. The use of stainless steel is mainly to maintain the original appearance of the building for a long time.
When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, raex 500 sheet material, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.
raex 500 sheet material, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.
