According to the European standard EN10025-3:2004, S275NL weldable fine grain structural steel is mainly used to manufacture the plants of factory, the common construction and construction machinery and equipment. For the bound technical terms,steel plate S275NL have to be done low temperature impacting test in rolling process at -50℃ with minimum energy 27J. Other additional requirements such as UT shall be according to EN 10160, and marine grade LR FH40 hull steel plate, steel plate S275NL customers can choose the relative classes for Ultrasonic test.
API 5L Gr.B steel plate is one mainly of Steel for large diameter pipes,API-Gr.B steel is manufactured using premium grade of raw material. These products marine grade LR FH40 hull steel plate are used to flow steam, water, oil and various petrochemicals substance in various petrochemical and chemical industries. These Steel Seamless Pipes are widely appreciated for high performance and less maintenance.
As the thickness and hardness of marine grade LR FH40 hull steel plate increase, the tendency to crack at the cutting edge increases. In order to prevent the marine grade LR FH40 hull steel plate from cutting cracks, preheating should be carried out before marine grade LR FH40 hull steel plate cutting. Special attention should be paid to preheating to make the entire marine grade LR FH40 hull steel plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole marine grade LR FH40 hull steel plate cannot be preheated, the partial preheating method can be used instead.
Q235 is a kind of carbon steel. marine grade LR FH40 hull steel plate, Q235 steel is widely used in steel structure construction because of its good toughness, good plasticity, certain elongation, good welding performance and heating performance. Q235A steel plate contains C ≤ 0.22%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.050, P ≤ 0.045. Q235B steel plate contains C ≤ 0.20%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.045, P ≤ 0.045. Q235C steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.040, P ≤ 0.040. Q235D steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.035, P ≤ 0.035.
