25CrMo4 tensile test top manufacturer in China
1.4306 characteristics and applications: X2CrNi189 stainless steel, German DIN standard stainless steel. It is equivalent to 00Cr19Ni10 in my country and SUS304L in Japan. The difference from 304L stainless steel is only in terms of nitrogen content and nickel content. The former is 0.04 and 10.1, and the latter is 0.06 and 8.3. This material distinction is common in the Swedish Avista series.
, 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.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
Since the beginning of this year, the global 25CrMo4 tensile test steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
